The delay parameter isn't set by any user, therefore simplify the code
and switch to the basic workqueue API w/o delay support. This also
reduces the size of struct mmc_host.

Bayhub chips have better compatibility support for SDR50 than DDR50
and both mode have the same R/W performance when clock frequency >= 100MHz.
Disable DDR50 mode and use SDR50 instead.

module: kunit: Load .kunit_test_suites section when CONFIG_KUNIT=m
mmc: sdhci-of-aspeed: test: Fix dependencies when KUNIT=m
If re-initialization results is a different signal voltage, because the
voltage switch failed previously, but not this time (or vice versa), then
sd3_bus_mode will be inconsistent with the card because the SD_SWITCH
command is done only upon first initialization.
Fix by always reading SD_SWITCH information during re-initialization, which
also means it does not need to be re-read later for the 1.8V fixup
workaround.
Note, brief testing showed SD_SWITCH took about 1.8ms to 2ms which added
about 1% to 1.5% to the re-initialization time, so it's not particularly
significant.

When introduced, upon success, the 1.8V fixup workaround in
mmc_sd_init_card() would branch to practically the end of the function, to
a label named "done". Unfortunately, perhaps due to the label name, over
time new code has been added that really should have come after "done" not
before it. Let's fix the problem by moving the label to the correct place
and rename it "cont".

While the sdhci-of-aspeed KUnit tests do work when builtin, and do work
when KUnit itself is being built as a module, the two together break.
This is because the KUnit tests (understandably) depend on KUnit, so a
built-in test cannot build if KUnit is a module.
Fix this by adding a dependency on (MMC_SDHCI_OF_ASPEED=m || KUNIT=y),
which only excludes this one problematic configuration.
This was reported on a nasty openrisc-randconfig run by the kernel test
robot, though for some reason (compiler optimisations removing the test
code?) I wasn't able to reproduce it locally on x86:

The commit 08f3dff799 (mmc: sdhci-of-dwcmshc: add rockchip platform

chips. Unfortunately, it also breaks the BlueField-3 FW, which uses ACPI.
To fix the problem, let's add the ACPI match data and the corresponding
quirks to re-enable the support for the BlueField-3 SoC.

Currently we don't clear MSDC interrupts when cqe off/disable, which led
to the data complete interrupt will be reserved for the next command.
If the next command with data transfer after cqe off/disable, we process
the CMD ready interrupt and trigger DMA start for data, but the data
complete interrupt is already exists, then SW assume that the data transfer
is complete, SW will trigger DMA stop, but the data may not be transmitted
yet or is transmitting, so we may encounter the following error:

This KUnit update for Linux 5.20-rc1 consists of several fixes and an
important feature to discourage running KUnit tests on production
systems. Running tests on a production system could leave the system
in a bad state. This new feature adds:
- adds a new taint type, TAINT_TEST to signal that a test has been run.
This should discourage people from running these tests on production
systems, and to make it easier to tell if tests have been run
accidentally (by loading the wrong configuration, etc.)
- several documentation and tool enhancements and fixes.

Merge ACPI device object management changes for v5.20-rc1.
- Use the facilities provided by the driver core and some additional
helpers to handle the children of a given ACPI device object in
multiple places instead of using the children and node list heads in
struct acpi_device which is error prone (Rafael Wysocki).
- Fix ACPI-related device reference counting issue in the hisi_lpc bus
driver (Yang Yingliang).
- Drop the children and node list heads that are not needed any more
from struct acpi_device (Rafael Wysocki).
- Drop driver member from struct acpi_device (Uwe Kleine-König).
- Drop redundant check from acpi_device_remove() (Uwe Kleine-König).

Add support for eint IRQ when MSDC is used as an SDIO host. This
feature requires SDIO device support async IRQ function. With this
feature, SDIO host can be awakened by SDIO card in suspend state,
without additional pin.
MSDC driver will time-share the SDIO DAT1 pin. During suspend, MSDC
turn off clock and switch SDIO DAT1 pin to GPIO mode. And during
resume, switch GPIO function back to DAT1 mode then turn on clock.
Some device tree property should be added or modified in MSDC node
to support SDIO eint IRQ. Pinctrls "state_eint" is mandatory. Since
this feature depends on asynchronous interrupts, "wakeup-source",
"keep-power-in-suspend" and "cap-sdio-irq" flags are necessary, and
the interrupts list should be extended(the interrupt named with
sdio_wakeup):
&mmcX {
...
interrupt-names = "msdc", "sdio_wakeup";
interrupts-extended = <...>,
<&pio xxx IRQ_TYPE_LEVEL_LOW>;
...
pinctrl-names = "default", "state_uhs", "state_eint";
...
pinctrl-2 = <&mmc2_pins_eint>;
...
cap-sdio-irq;
keep-power-in-suspend;
wakeup-source;
...
};

The oldest commit 466614a976 ("mmc: sdhci-msm: Add SoC specific
compatibles") did not specify what benefits such multiple compatibles
bring, therefore assume there is none. On the other hand such approach
brings a lot of churn to driver maintenance by expecting commit for
every new compatible, even though it is already covered by the fallback.
There is really no sense in duplicating of_device_id for each
variant, which is already covered by generic compatible fallback

Due to flaws in hardware design, GL9763E takes long time to exit from L1
state. The I/O performance will suffer severe impact if it often enter and
exit L1 state during I/O requests.
To improve I/O read/write performance and take battery life into account,
let's turn on GL9763E L1 negotiation before entering runtime suspend and
turn off GL9763E L1 negotiation while executing runtime resume. That is to
say, GL9763E will not enter L1 state when executing I/O requests and enter
L1 state when PCIe bus idle.

rate to be increased from a max of 100MHz to a max of 150MHz. The
driver will need to get the clock and increase it's default rate
and override the caps register, that still indicates a max of 100MHz.
The new clock will be named "sdio_freq" in the DT node's "clock-names"
list. The driver will use a DT property, "clock-frequency", to
enable this functionality and will get the actual rate in MHz
from the property to allow various speeds to be requested.

The reset function build in the SDHCI will not reset the logic
circuit related to the tuning function, which may cause data

The kunit_test_suite() macro is no-longer incompatible with module_add,
so its use can be reinstated.
Since this fixes parsing with builtins and kunit_tool, also enable the
test by default when KUNIT_ALL_TESTS is enabled.
The test can now be run via kunit_tool with:
./tools/testing/kunit/kunit.py run --arch=x86_64 \
--kconfig_add CONFIG_OF=y --kconfig_add CONFIG_OF_ADDRESS=y \
--kconfig_add CONFIG_MMC=y --kconfig_add CONFIG_MMC_SDHCI=y \
--kconfig_add CONFIG_MMC_SDHCI_PLTFM=y \
--kconfig_add CONFIG_MMC_SDHCI_OF_ASPEED=y \
'sdhci-of-aspeed'
(It may be worth adding a .kunitconfig at some point, as there are
enough dependencies to make that command scarily long.)

With new API blk_mq_is_reserved_rq() we can tell if a request is from
the reserved pool, so stop passing 'reserved' arg. There is actually
only a single user of that arg for all the callback implementations, which
can use blk_mq_is_reserved_rq() instead.
This will also allow us to stop passing the same 'reserved' around the
blk-mq iter functions next.

Set the queue dying flag and call blk_mq_exit_queue from del_gendisk for
all disks that do not have separately allocated queues, and thus remove
the need to call blk_cleanup_queue for them.
Rename blk_cleanup_disk to blk_mq_destroy_queue to make it clear that
this function is intended only for separately allocated blk-mq queues.
This saves an extra queue freeze for devices without a separately
allocated queue.

Introduce acpi_device_fix_up_power_extended() for fixing up power of
a device having an ACPI companion in a manner that takes the device's
children into account and make the MMC code use it in two places
instead of walking the list of the device ACPI companion's children
directly.
This will help to eliminate the children list head from struct
acpi_device as it is redundant and it is used in questionable ways
in some places (in particular, locking is needed for walking the
list pointed to it safely, but it is often missing).

MediaTek IP requires that after dma stop, it need to wait this dma stop
bit auto-reset to 0. When bus is in high loading state, it will take a
while for the dma stop complete. If there is no waiting operation here,
when program runs to clear fifo and reset, bus will hang.
In addition, there should be no return in msdc_data_xfer_next() if
there is data need be transferred, because no matter what error occurs
here, it should continue to excute to the following mmc_request_done.
Otherwise the core layer may wait complete forever.

The second part of the multiplatform changes now converts the
Intel/Marvell PXA platform along with the rest. The patches went through
several rebases before the merge window as bugs were found, so they
remained separate.
This has to touch a lot of drivers, in particular the touchscreen,
pcmcia, sound and clk bits, to detach the driver files from the
platform and board specific header files.

The intention of the use of mmc_blk_reset_success() in
mmc_blk_cqe_recovery() was to prevent repeated resets when retrying and
getting the same error. However, that may not be the case - any amount
of time and I/O may pass before another recovery is needed, in which
case there would be no reason to deny it the opportunity to recover via
a reset if necessary. CQE recovery is expected seldom and failure to
recover (if the clear tasks command fails), even more seldom, so it is
better to allow the reset always, which can be done by calling
mmc_blk_reset_success() always.

It turned out that polling period for MMC_SEND_OP_COND, that currently is
set to 1ms, still isn't sufficient. In particular a Micron eMMC on a
Beaglebone platform, is reported to sometimes fail to initialize.
Additional test, shows that extending the period to 4ms is working fine, so
let's make that change.

After a build regression report, I took a look at possible users of
CONFIG_ISA_DMA_API on m68k and found none, which Greg confirmed. The
CONFIG_GENERIC_ISA_DMA option in turn is only needed to implement
ISA_DMA_API, and is clearly not used on the platforms with ISA support.
The CONFIG_ISA support for AMIGA_PCMCIA is probably also unneeded,
but this is less clear. Unlike other PCMCIA implementations, this one
does not use the drivers/pcmcia subsystem at all and just supports
the "apne" network driver. When it was first added, one could use
ISA drivers on it as well, but this probably broke at some point.
With no reason to keep this, let's just drop the corresponding files
and prevent the remaining ISA drivers that use this from getting built.
The remaining definitions in asm/dma.h are used for PCI support.

Enabling this feature will allow the controller to stop the bus
clock when the bus is idle. The feature is not part of the standard

Newer variants of the MMC controller support a 34-bit physical address
space by using word addresses instead of byte addresses. However, the
code truncates the DMA descriptor address to 32 bits before applying the
shift. This breaks DMA for descriptors allocated above the 32-bit limit.

To make the entropy pool a bit better we can toss in the

This does not count as improvement of the entropy but

userspace application. This patch allows custom timeout values to override this default

In cases where this can't be connected, add a quirk to force the

Despite mmc_ioc_multi_cmd::num_of_cmds is a 64-bit field, its maximum
value is limited to MMC_IOC_MAX_CMDS (only 255); using a 64-bit local
variable to hold a copy of that field leads to gcc generating ineffective
loop code: despite the source code using an *int* variable for the loop
counters, the 32-bit object code uses 64-bit unsigned counters. Also,
gcc has to drop the most significant word of that 64-bit variable when
calling kcalloc() and assigning to mmc_queue_req::ioc_count anyway.
Using the *unsigned int* variable instead results in a better code.

It is not explicitly expressed in the docs, but the needed data strobe
pin is indeed missing for D3. The BSP disables HS400 as well. This means
a little refactoring to reuse an already existing setup.

Way back in commit 4f25580fb8 ("mmc: core: changes frequency to
hs_max_dtr when selecting hs400es"), Rockchip engineers noticed that
some eMMC don't respond to SEND_STATUS commands very reliably if they're
still running at a low initial frequency. As mentioned in that commit,
JESD84-B51 P49 suggests a sequence in which the host:
1. sets HS_TIMING
2. bumps the clock ("<= 52 MHz")
3. sends further commands
It doesn't exactly require that we don't use a lower-than-52MHz
frequency, but in practice, these eMMC don't like it.
The aforementioned commit tried to get that right for HS400ES, although
it's unclear whether this ever truly worked as committed into mainline,
as other changes/refactoring adjusted the sequence in conflicting ways:
08573eaf1a ("mmc: mmc: do not use CMD13 to get status after speed mode
switch")
53e60650f7 ("mmc: core: Allow CMD13 polling when switching to HS mode
for mmc")
In any case, today we do step 3 before step 2. Let's fix that, and also
apply the same logic to HS200/400, where this eMMC has problems too.
Resolves errors like this seen when booting some RK3399 Gru/Scarlet
systems:

[ 2.841751] mmc1: error -110 whilst initialising MMC card
Ealier versions of this patch bumped to 200MHz/HS200 speeds too early,
which caused issues on, e.g., qcom-msm8974-fairphone-fp2. (Thanks for
the report Luca!) After a second look, it appears that aligns with
JESD84 / page 45 / table 28, so we need to keep to lower (HS / 52 MHz)
rates first.

The mach/hardware.h is included in lots of places, and it provides
three different things on pxa:
- the cpu_is_pxa* macros
- an indirect inclusion of mach/addr-map.h
- the __REG() and io_pv2() helper macros
Split it up into separate <linux/soc/pxa/cpu.h> and mach/pxa-regs.h
headers, then change all the files that use mach/hardware.h to
include the exact set of those three headers that they actually
need, allowing for further more targeted cleanup.
linux/soc/pxa/cpu.h can remain permanently exported and is now in
a global location along with similar headers. pxa-regs.h and
addr-map.h are only used in a very small number of drivers now
and can be moved to arch/arm/mach-pxa/ directly when those drivers
are to pass the necessary data as resources.

Just use a non-zero max_discard_sectors as an indicator for discard
support, similar to what is done for write zeroes.

During the card initialization process, the mmc core checks whether the
eMMC/SD card supports an internal writeback-cache and then enables it
inside the card.
Unfortunately, this isn't according to what the mmc core reports to the
upper block layer. Instead, the writeback-cache support with REQ_FLUSH and
REQ_FUA, are being enabled depending on whether the host supports the CMD23
(MMC_CAP_CMD23) and whether an eMMC supports the reliable-write command.
This is wrong and it may also sound awkward. In fact, it's a remnant
from when both eMMC/SD cards didn't have dedicated commands/support to
control the internal writeback-cache. In other words, it was the best we
could do at that point in time.
To fix the problem, but also without breaking backwards compatibility,
let's align the REQ_FLUSH support with whether the writeback-cache became
successfully enabled - for both eMMC and SD cards.

Introduce a SEND_STATUS check for writes through SPI to not mark
an unsuccessful write as successful.
Since SPI SD/MMC does not have states, after a write, the card will
just hold the line LOW until it is ready again. The driver marks the
write therefore as completed as soon as it reads something other than
all zeroes.
The driver does not distinguish from a card no longer signalling busy
and it being disconnected (and the line being pulled-up by the host).
This lead to writes being marked as successful when disconnecting
a busy card.
Now the card is ensured to be still connected by an additional CMD13,
just like non-SPI is ensured to go back to TRAN state.
While at it and since we already poll for the post-write status anyway,
we might as well check for SPIs error bits (any of them).
The disconnecting card problem is reproducable for me after continuous
write activity and randomly disconnecting, around every 20-50 tries
on SPI DS for some card.

The overwhelming bulk of this pull request is a change from Uwe
Kleine-König which changes the return type of the remove() function to
void as part of some wider work he's doing to do this for all bus types,
causing updates to most SPI device drivers. The branch with that on has
been cross merged with a couple of other trees which added new SPI
drivers this cycle, I'm not expecting any build issues resulting from
the change.
Otherwise it's been a relatively quiet release with some new device
support, a few minor features and the welcome completion of the
conversion of the subsystem to use GPIO descriptors rather than numbers:
- Change return type of remove() to void.
- Completion of the conversion of SPI controller drivers to use GPIO
descriptors rather than numbers.
- Quite a few DT schema conversions.
- Support for multiple SPI devices on a bus in ACPI systems.
- Big overhaul of the PXA2xx SPI driver.

When mmc_select_hs400es() tries to switch to the HS400 ES mode, it may bail
out early if the host doesn't support an 8-bit buswidth, as it's required
for the HS400 mode.
To improve the situation, let's instead drop the HS400 bits from the
capability field if the 8-bit bus isn't supported. In this way, we allow
the mmc initialization to continue by trying a lower speed mode.

Even if the current WARN() notifies the user that something is severely
wrong, we can still end up in a PANIC() when trying to invoke the missing
->enable_sdio_irq() ops. Therefore, let's also return an error code and
prevent the host from being added.
While at it, move the code into a separate function to prepare for
subsequent changes and for further host caps validations.

In the error path of mmc_select_hs200() we are trying our best to restore
the card/host into a valid state. This makes sense, especially if we
encounter a simple switch error (-EBADMSG). However, rather than then
continue with using the legacy speed mode, let's try the other better speed
modes first. Additionally, let's update the card->mmc_avail_type to avoid
us from trying a broken HS200 mode again.
In an Amlogic S905W based TV box where the switch to HS200 mode fails for
the eMMC, this allows us to use the eMMC in DDR mode in favor of the legacy
mode, which greatly improves the performance.

The Rockchip rk356x ciu clock cannot be set as low as the dw-mmc
hardware supports. This leads to a situation during card initialization
where the clock is set lower than the clock driver can support. The
dw-mmc-rockchip driver spews errors when this happens.
For normal operation this only happens a few times during boot, but when
cd-broken is enabled (in cases such as the SoQuartz module) this fires
multiple times each poll cycle.
Fix this by testing the lowest possible frequency that the clock driver
can support which is within the mmc specification. Divide that rate by
the internal divider and set f_min to this.

Host drivers may not be able to support frequencies as low as dw-mmc
supports. Unfortunately f_min isn't available when the drv_data->init
function is called, as the mmc_host struct hasn't been set up yet.
Support the host drivers saving the requested minimum frequency, so we
can later set f_min when it is available.

Commit 76bfc7ccc2 ("mmc: core: adjust polling interval for CMD1"),
significantly decreased the polling period from ~10-12ms into just a couple
of us. The purpose was to decrease the total time spent in the busy polling
loop, but unfortunate it has lead to problems, that causes eMMC cards to
never gets out busy and thus fails to be initialized.
To fix the problem, but also to try to keep some of the new improved
behaviour, let's start by using a polling period of 1-2ms, which then
increases for each loop, according to common polling loop in
__mmc_poll_for_busy().

Until now, the SDIO quirks are applied directly from the driver.
However, it is better to apply the quirks before driver probing. So,
this patch relocate the quirks in the MMC framework.
Note that the WF200 has no valid SDIO VID/PID. Therefore, we match DT
rather than on the SDIO VID/PID.

The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

On reads with MMC_READ_MULTIPLE_BLOCK that fail,
the recovery handler will use MMC_READ_SINGLE_BLOCK for
each of the blocks, up to MMC_READ_SINGLE_RETRIES times each.
The logic for this is fixed to never report unsuccessful reads
as success to the block layer.
On command error with retries remaining, blk_update_request was
called with whatever value error was set last to.
In case it was last set to BLK_STS_OK (default), the read will be
reported as success, even though there was no data read from the device.
This could happen on a CRC mismatch for the response,
a card rejecting the command (e.g. again due to a CRC mismatch).
In case it was last set to BLK_STS_IOERR, the error is reported correctly,
but no retries will be attempted.

Commit 5b4258f672 ("misc: rtsx: rts5249 support runtime PM") doesn't
use pm_runtime_{get,put}() helpers when it should, so the RPM refcount
keeps at zero, hence its parent driver, rtsx_pci, has to do lots of
weird tricks to keep it from runtime suspending.
So use those helpers at right places to properly manage runtime PM.

SD card is allowed to signal busy on DAT0 up to 1s after the
CMD49. According to SD spec (version 6.0 section 5.8.1.3) first host
waits until busy of CMD49 is released and only then polls Power
Management Status register up to 1s until the card indicates ready to
power off.
Without waiting for busy before polling status register sometimes card
becomes unresponsive and system fails to suspend:

Because of the possible failure of the dma_supported(), the
dma_set_mask_and_coherent() may return error num.
Therefore, it should be better to check it and return the error if

And since the sdhci_setup_host() has already checked the return value of

they're mostly minor cleanups and some debugfs stuff. The real work
that's in here is the typical pile of clk driver updates and new SoC

handful of SoC drivers additions and has the largest diffstat. After
that there are quite a few updates to the Allwinner (sunxi) drivers to
support modular drivers and Renesas is heavily updated to add more
support for various clks. Overall it looks pretty normal.
New Drivers:
- Add MDMA and BDMA clks to Ingenic JZ4760 and JZ4770
- MediaTek mt7986 SoC basic support
- Clock and reset driver for Toshiba Visconti SoCs
- Initial clock driver for the Exynos7885 SoC (Samsung Galaxy A8)
- Allwinner D1 clks
- Lan966x Generic Clock Controller driver and associated DT bindings
- Qualcomm SDX65, SM8450, and MSM8976 GCC clks
- Qualcomm SDX65 and SM8450 RPMh clks
Updates:
- Set suppress_bind_attrs to true for i.MX8ULP driver
- Switch from do_div to div64_ul for throughout all i.MX drivers
- Fix imx8mn_clko1_sels for i.MX8MN
- Remove unused IPG_AUDIO_ROOT from i.MX8MP
- Switch parent for audio_root_clk to audio ahb in i.MX8MP driver
- Removal of all remaining uses of __clk_lookup() in drivers/clk/samsung
- Refactoring of the CPU clocks registration to use common interface
- An update of the Exynos850 driver (support for more clock domains)
required by the E850-96 development board
- Prep for runtime PM and generic power domains on Tegra
- Support modular Allwinner clk drivers via platform bus
- Lan966x clock driver extended to support clock gating
- Add serial (SCI1), watchdog (WDT), timer (OSTM), SPI (RSPI), and
thermal (TSU) clocks and resets on Renesas RZ/G2L
- Rework SDHI clock handling in the Renesas R-Car Gen3 and RZ/G2 clock
drivers, and in the Renesas SDHI driver
- Make the Cortex-A55 (I) clock on Renesas RZ/G2L programmable
- Document support for the new Renesas R-Car S4-8 (R8A779F0) SoC
- Add support for the new Renesas R-Car S4-8 (R8A779F0) SoC

Pull power management updates from Rafael Wysocki:
"The most signigicant change here is the addition of a new cpufreq
'P-state' driver for AMD processors as a better replacement for the
venerable acpi-cpufreq driver.

drivers), PM core updates (mostly related to adding new macros for
declaring PM operations which should make the lives of driver
developers somewhat easier), and a bunch of assorted fixes and
cleanups.

In commit 3c1a884436 ("mmc: mediatek: add support of source_cg clock")
an independent cg was introduced to avoid a hardware hang issue during
clock mode switches (subsequent commits will set that clock as optional).
When this clock is not present in device-tree, any operation is being
done on src_clk's parent (calling clk_get_parent()): to simplify this
and avoid checking for src_clk_cg presence everytime, just assign the
parent clock to src_clk_cg and remove the now useless checks.

Since the MMC/SD controller in Ingenic SoCs work in half-duplex, it is
possible to use one single DMA channel for both TX and RX operations,
instead of using separate channels.
As some older Ingenic SoCs offer only a handful of DMA channels,
supporting bi-directional channels allow more hardware to use the
channels that would otherwise be used for the MMC/SD operation.

When running the ARTPEC-8 DWMMC IP version, and a data error interrupt
comes during a data read transfer, there is no guarantee for the data
transfer over interrupt (DTO) to come within the specified data timeout.
This case is handled by the dto_timer handler which will complete the
request with the comment:
/*
* If DTO interrupt does NOT come in sending data state,
* we should notify the driver to terminate current transfer
* and report a data timeout to the core.
*/
But since the ARTPEC-8 DWMMC IP version, supports an extended TMOUT
register which allows longer timeouts than the non ARTPEC-8 version
does, waiting for the dto_timer to complete the request in error cases
may cause the request to take significantly longer time than necessary.
This is specifically true for the failing steps during tuning of a
device.
Fix this by completing the request when the error interrupt comes. Since
this fix is specific for the ARTPEC-8, a quirk is added.

Current dw_mci driver supports a TMOUT register which consists of a 24
bit field (TMOUT[31:8]) for the DATA_TIMEOUT. The maximum value of this
field is 0xFFFFFF, which with a 200MHz clock will give a full DRTO of:
0xFFFFFF / 200000000 => ~84 ms
However, the ARTPEC-8 SoC DWMMC IP version has a TMOUT register with an
extended DATA_TIMEOUT field, which supports longer timers for the DRTO.
In this version the DATA_TIMEOUT field is split into two, which with the
same 200MHz clock as above will allow a maximum timeout of:
((TMOUT[10:8] -1) * 0xFFFFFF + TMOUT[31:11] * 8) / 200000000 => ~587 ms
Add driver callbacks for implementation specific data timeout, and
implement callback functions for the ARTPEC-8 SoC.

During test campaign, and especially after several unbind/bind sequences,
it has been seen that the SD-card on SDMMC1 thread could freeze.
The freeze always appear on a CMD23 following a CMD19.
Checking SDMMC internal registers shows that the tuning command (CMD19)
has failed.
The freeze is then due to the delay block involved in the tuning sequence.
To correct this, clear the delay block register DLYB_CR register after
the tuning commands.

It's seems prone to problems by allowing card detect and its corresponding
mmc_rescan() work to run, during platform shutdown. For example, we may end
up turning off the power while initializing a card, which potentially could
damage it.
To avoid this scenario, let's add ->shutdown_pre() callback for the mmc host
class device and then turn of the card detect from there.

Use DEFINE_SIMPLE_DEV_PM_OPS() instead of the SIMPLE_DEV_PM_OPS()
macro, along with using pm_sleep_ptr() as this driver doesn't handle
runtime PM.
This makes it possible to remove the #ifdef CONFIG_PM guard around
the suspend/resume functions.

on the callback functions.
- Since we only have callbacks for suspend/resume, we can conditionally
compile the dev_pm_ops structure for when CONFIG_PM_SLEEP is enabled;
so use the pm_sleep_ptr() macro instead of pm_ptr().

The SDHCI on Tegra belongs to the core power domain and we're going to
enable GENPD support for the core domain. Now SDHCI must be resumed using
runtime PM API in order to initialize the SDHCI power state. The SDHCI
clock rate must be changed using OPP API that will reconfigure the power
domain performance state in accordance to the rate. Add runtime PM and OPP
support to the SDHCI driver.

If there is no driver match function, the driver core assumes that each
candidate pair (driver, device) matches, see driver_match_device().
Drop the mmc bus's match function that always returned 1 and so implements
the same behaviour as when there is no match function.

Move the common MMC_CAP_CMD23 capability to common_caps so that only the
special case of MMC_CAP_1_8V_DDR and MMC_CAP_8_BIT_DATA are set via
caps/num_caps. Both of those can, and should, be set via device tree
properties instead, so we can now say that exynos_dwmmc_caps is only
used for backwards compatibility.

The TMOUT register is always set with a full value for every transfer,
which (with a 200MHz clock) will give a full DRTO of ~84 milliseconds.
This is normally good enough to complete the request, but setting a full
value makes it impossible to test shorter timeouts, when for example
testing data read times on different SD cards.
Add a function to set any value smaller than the maximum of 0xFFFFFF.

In mmc_send_op_cond(), loops are continuously performed at the same
interval of 10 ms. However the behaviour is not good for some eMMC
which can be out from a busy state earlier than 10 ms if normal.
Rather than fixing about the interval time in mmc_send_op_cond(),
let's instead convert into using the common __mmc_poll_for_busy().
The reason for adjusting the interval time is that it is important
to reduce the eMMC initialization time, especially in devices that
use eMMC as rootfs.

If we get a data error during a block transfer command, a stop command
(CMD12) is normally initiated. But this does not work for the general
command (CMD56), but instead the action is ignored and an uninitialized
command struct is used for the stop action, with unexpected result.
Fix this by adding a check for GEN_CMD when preparing stop transmission.

Due to recent changes to the mmc core, card quirks can be applied based
upon a compatible string in child OF node. The quirk needed for wl1251
(SDIO card) is managed in the core, therefore there is no longer any reason
to deal with this in omap_hsmmc too, so let's remove it.

The TiWi WL1251 WiFi chip needs special setup of the sdio
interface before it can be probed.
So far, this is done in omap_hsmmc_init_card() in omap_hsmmc.c
which makes it useable only if connected to omap devices
which use the omap_hsmmc. The OpenPandora is the most promient
example.
There are plans to switch to a newer sdhci-omap driver and
retire omap_hsmmc. Hence this quirk must be reworked or moved
somewhere else. Ideally to some location that is not dependent
on the specific SoC mmc host driver.
This is achieved by the new mmc_fixup_device() option introduced
by ("mmc: allow to match the device tree to apply quirks") to match
through device tree compatible string.
This quirk will be called early right after where host->ops->init_card()
and thus omap_hsmmc_init_card() was previously called.
Note that we do not need to transplant
card->ocr = 0x80;
because we rely on ("mmc: core: Fixup storing of OCR for MMC_QUIRK_NONSTD_SDIO").

The mmc core takes a specific path to support initializing of a
non-standard SDIO card. This is triggered by looking for the card-quirk,
MMC_QUIRK_NONSTD_SDIO.
In mmc_sdio_init_card() this gets rather messy, as it causes the code to
bail out earlier, compared to the usual path. This leads to that the OCR
doesn't get saved properly in card->ocr. Fortunately, only omap_hsmmc has
been using the MMC_QUIRK_NONSTD_SDIO and is dealing with the issue, by
assigning a hardcoded value (0x80) to card->ocr from an ->init_card() ops.
To make the behaviour consistent, let's instead rely on the core to save
the OCR in card->ocr during initialization.
