Drop more omap3 legacy board-*.c files for v4.2. This time we're
dropping the board files for beagle, overo and cm-t35.
The reason for dropping these now rather than later is that now
we can simply revert the patches in case of unexpected issues as
we are not dropping any platform data at this point.
This leaves us with only the following board-*.c files:
BOARD REASON NEEDED
board-ldp.c Still used in RMKs boot test system
board-omap3logic.c Getting a .dts file for v4.2
board-omap3pandora.c Got a .dts file for v4.1
board-rx51-*.c Needs /proc/atags support for user space
I'm hoping we can drop the remaining board-*.c for v4.3 merge
window, then keep the platform data around for one more merge
window in case of reverting needed, then drop the platform data
too for v4.4 if no issues needing reverting are found.
Also, few patches to clean-up the usage of Linux generic
macros:
- Use define for console loglevel
- Use const for struct irq_domain_ops
- Use PTR_ERR_OR_ZERO instead of PTR_RET

If we use a combination of VMODE and I2C4 for retention modes,
eventually the off idle power consumption will creep up by about
23mW, even during off mode with I2C4 always staying enabled.
Turns out this is because of erratum i531 "Extra Power Consumed
When Repeated Start Operation Mode Is Enabled on I2C Interface
Dedicated for Smart Reflex (I2C4)" as pointed out by Nishanth
Menon <nm@ti.com>.
Let's fix the issue by adding i2c_cfg_clear_mask for the bits
to clear when initializing the I2C4 adapter so we can clear
SREN bit that drives the I2C4 lines low otherwise when there
is no traffic.

Pull ARM DT updates from Olof Johansson:
"As always, this tends to be one of our bigger branches. There are
lots of updates this release, but not that many jumps out as something
that needs more detailed coverage. Some of the highlights are:
- DTs for the new Annapurna Labs Alpine platform
- more graphics DT pieces falling into place on Exynos, bridges,
clocks.
- plenty of DT updates for Qualcomm platforms for various IP blocks
- some churn on Tegra due to switch-over to tool-generated pinctrl
data
- misc fixes and updates for Atmel at91 platforms
- various DT updates to add IP block support on Broadcom's Cygnus
platforms
- more updates for Renesas platforms as DT support is added for
various IP blocks (IPMMU, display, audio, etc)"

platform code. In this case, that includes:
- Support for the new Annapurna Labs "Alpine" platform
- A rework greatly simplifying adding new platform support to the MCPM

- Cpuidle and PM improvements for Exynos3250
- Misc updates for Renesas, OMAP, Meson, i.MX. Some of these could have

support
- OMAP removes legacy board files for three more platforms
- Removal of non-DT mach-msm, newer Qualcomm platforms now live in mach-qcom
- Freescale i.MX25 also removes non-DT platform support
Most of the rest of the changes here are fallout from the above, i.e. for
example removal of drivers that now lack platforms, etc.

The ones at subdev-formats.xml and media-bus-format.h are not trivial.
That's why we opted to merge from DRM.
With the recent changes omaps have developed a dependency to MFD_SYSCON.
This is used for system control module generic register area and some
clocks.
We do have it selected in omap2plus_defconfig, but targeted config

few other ARM platforms are already doing.

items that sort of fall into the new feature category.
First off, we have new callbacks for PM domains that should help us to
handle some issues related to device initialization in a better way.
There also is some consolidation in the unified device properties API
area allowing us to use that inferface for accessing data coming from
platform initialization code in addition to firmware-provided data.
We have some new device/CPU IDs in a few drivers, support for new
chips and a new cpufreq driver too.
Specifics:
- Generic PM domains support update including new PM domain callbacks
to handle device initialization better (Russell King, Rafael J
Wysocki, Kevin Hilman)
- Unified device properties API update including a new mechanism for
accessing data provided by platform initialization code (Rafael J
Wysocki, Adrian Hunter)
- ARM cpuidle update including ARM32/ARM64 handling consolidation
(Daniel Lezcano)
- intel_idle update including support for the Silvermont Core in the
Baytrail SOC and for the Airmont Core in the Cherrytrail and
Braswell SOCs (Len Brown, Mathias Krause)
- New cpufreq driver for Hisilicon ACPU (Leo Yan)
- intel_pstate update including support for the Knights Landing chip
(Dasaratharaman Chandramouli, Kristen Carlson Accardi)
- QorIQ cpufreq driver update (Tang Yuantian, Arnd Bergmann)
- powernv cpufreq driver update (Shilpasri G Bhat)
- devfreq update including Tegra support changes (Tomeu Vizoso,
MyungJoo Ham, Chanwoo Choi)
- powercap RAPL (Running-Average Power Limit) driver update including
support for Intel Broadwell server chips (Jacob Pan, Mathias Krause)
- ACPI device enumeration update related to the handling of the
special PRP0001 device ID allowing DT-style 'compatible' property
to be used for ACPI device identification (Rafael J Wysocki)
- ACPI EC driver update including limited _DEP support (Lan Tianyu,
Lv Zheng)
- ACPI backlight driver update including a new mechanism to allow
native backlight handling to be forced on non-Windows 8 systems and
a new quirk for Lenovo Ideapad Z570 (Aaron Lu, Hans de Goede)
- New Windows Vista compatibility quirk for Sony VGN-SR19XN (Chen Yu)
- Assorted ACPI fixes and cleanups (Aaron Lu, Martin Kepplinger,
Masanari Iida, Mika Westerberg, Nan Li, Rafael J Wysocki)
- Fixes related to suspend-to-idle for the iTCO watchdog driver and
the ACPI core system suspend/resume code (Rafael J Wysocki, Chen Yu)
- PM tracing support for the suspend phase of system suspend/resume
transitions (Zhonghui Fu)
- Configurable delay for the system suspend/resume testing facility
(Brian Norris)
- PNP subsystem cleanups (Peter Huewe, Rafael J Wysocki)"

Make omap3isp configuration data structures more suitable for consumption by
the DT by separating the I2C bus information of all the sub-devices in a
group and the ISP bus information from each other. The ISP bus information
is made a pointer instead of being directly embedded in the struct.
In the case of the DT only the sensor specific information on the ISP bus
configuration is retained. The structs are renamed to reflect that.
After this change the structs needed to describe device configuration can be
allocated and accessed separately without those needed only in the case of
platform data. The platform data related structs can be later removed once
the support for platform data can be removed.

On Cortex-A15 (r0p0..r3p2) the TLBI*IS/DSB operations are not

board-rx51 has no card detect pin in the mmc slot, but can detect that
the (cell-phone) cover has been removed and the card is accessible.
The semantics between cover/card detect differ, the gpio on the slot
informs you after the card has been removed, cover removal does not
necessarily mean that the card has been removed.
This means different code paths are necessary. To complete this we
also want different fields in the platform data for cover and card
detect. This separation is not pushed all the way down into struct
omap2_hsmmc_info which is used to initialize the platform data.
If we did that we had to go over all board files and set the new
gpio_cod pin to -EINVAL. If we forget one board or some out-of-tree
archicture forgets that the default '0' is used which is a valid pin
number.

There is no need to provide the control module base address through a
low-level API from the low-level IO init, as this information is
available through DT. This patch adds a new API to initialize the
control module though, but mostly makes the old API obsolete. The
old API can be completely removed once OMAP3 is made DT only.

Splits the clock related provider module inits under their own driver files.
Previously this was done for all modules under the common PRM driver.
Signed-off-by: Tero Kristo <t-kristo@ti.com>
Splits the clock provider init out of the PRM driver and moves it to
clock driver. This is needed so that once the PRCM drivers are separated,
they can logically just access the clock driver not needing to go through
common PRM code. This would be wrong in the case of control module for
example.

We've been moving all omap2+ based systems to boot in device tree only
mode for a few years now. Only omap3 has legacy booting support
remaining. Most omap3 boards already have related arch/arm/boot/*.dts*
files for booting with device tree.
As it seems this board only has minimal support upstreamed for the
legacy booting and has not seen activity for on the mailing lists
for a few years, let's attempt to remove the related legacy board-*.c
file.
I do not have this board, but it seems getting the same level of
support with device tree based booting is mostly just configuring
the .dts file. And there is no need to upgrade the boot loader as
we can boot with appended DTB too. And most of the omap3 boards
seem to be related to omap3-evm, and omap3beagleboard that are
supported with device tree based booting.
If somebody is using this board actively with the mainline kernel,
please communicate this to the linux-omap mailing list so we can
get the board booting with device tree based support. I can help
some too getting the minimal device tree based booting going if
help is needed.
The reason for attempting to remove this board now is that I'd
rather get the remaining omap3 legacy booting support into a known
state where we at least have a .dts file being written for the
remaining legacy boards. That is because for the next few merge
cycles we can still revert this patch if absolutely necessary,
but I'd rather not get suprised by missing .dts files at the point
where we are ready to drop all remaining omap3 legacy booting
support later on.

The Kconfig-Option OMAP4_ERRATA_I688 is never visible due to a
contradiction in it's dependencies.
The option requires ARCH_MULTIPLATFORM to be 'disabled'. However, an
enclosing menu requires either ARCH_MULTI_V6 or ARCH_MULTI_V7 to be
enabled. These options inherit a dependency from an enclosing menu,
that requires ARCH_MULTIPLATFORM to be 'enabled'.
This is a contradiction and made this option also unavailable for
non-multiplatform configurations.
Since there are no selects on OMAP4_ERRATA_I688, which would ignore
dependencies, the code related to that option is dead and can be
removed.
This (logical) defect has been found with the undertaker tool.

Support for the TI crossbar used on the DRA7 family of chips

Converting it to stacked domains makes it slightly more

even though the access is defined as asynchronous, and no GPMC_CLK clock
is provided to the external device. Still, GPMCFCLKDIVIDER is used as a divider
for the GPMC clock, so it must be programmed to define the
correct WAITMONITORINGTIME delay.

Previously this module mode offset was part of pcie PHY which was wrong.
Now this module mode offset was moved to pcie hwmod and removed the hwmod data

to match with the name given in TRM.
This helps to get rid of the following warning

Add struct lock_class_key to omap_hwmod struct and use it to set unique

This will ensure that lockdep will know that each omap_hwmod->_lock should
be treated as separate class and will not give false warning about deadlock
or other issues due to nested use of hwmods.
DRA7x's ATL hwmod is one example for this since McASP can select ATL clock
as functional clock, which will trigger nested oh->_lock usage. This will
trigger false warning from lockdep validator as it is dealing with classes
and for it all hwmod clocks are the same class.

New and updated SoC support. Also included are some cleanups where the
platform maintainers hadn't separated cleanups from new developent in
separate branches.
Some of the larger things worth pointing out:
- A large set of changes from Alexandre Belloni and Nicolas Ferre
preparing at91 platforms for multiplatform and cleaning up quite a
bit in the process.
- Removal of CSR's "Marco" SoC platform that never made it out to the
market. We love seeing these since it means the vendor published
support before product was out, which is exactly what we want!
New platforms this release are:
- Conexant Digicolor (CX92755 SoC)
- Hisilicon HiP01 SoC
- CSR/sirf Atlas7 SoC
- ST STiH418 SoC
- Common code changes for Nvidia Tegra132 (64-bit SoC)
We're seeing more and more platforms having a harder time labelling
changes as cleanups vs new development -- which is a good sign that
we've come quite far on the cleanup effort. So over time we might start
combining the cleanup and new-development branches more.

Remove omap_clocks_register and dummy_ck. The former is not used anymore
now that the statically defined clk stuctures are replaced with proper
descriptors and registered with the framework.
The dummy clock in arch/arm/mach-omap2 is made redundant by the OMAP3+
clock data that migrated to drivers/clk.
An additional benefit to this clean-up is removing the references to
clk-private.h which will be removed.

Moves clock state to struct clk_core, but takes care to change as little API as
possible.
struct clk_hw still has a pointer to a struct clk, which is the
implementation's per-user clk instance, for backwards compatibility.
The struct clk that clk_get_parent() returns isn't owned by the caller, but by
the clock implementation, so the former shouldn't call clk_put() on it.
Because some boards in mach-omap2 still register clocks statically, their clock
registration had to be updated to take into account that the clock information
is stored in struct clk_core now.

As the legacy clock data is being moved under clock driver, the
clock data will be using the same low level infrastructure for
register accesses. This requires the clk_memmaps to be initialized
properly. This patch adds a support hook to the PRM driver to

Add minimal hwmod support that works at least on dm8168. This
is based on the code in the earlier TI CDP tree, and an earlier
patch by Aida Mynzhasova <aida.mynzhasova@skitlab.ru>.
I've set up things to work pretty much the same way as for
am33xx. We are basically using cm33xx.c with a different set
of clocks and clockdomains.

This patch adds required definitions and structures for clockdomain
initialization, so omap3xxx_clockdomains_init() was substituted by
new ti81xx_clockdomains_init() while early initialization of
TI81XX platform.
Note that we now need to have 81xx in a separate CONFIG_SOC_TI81XX
block instead inside the ifdef block for omap3 to avoid make
randconfig build errors.
This code is based on the TI81XX-LINUX-PSP-04.04.00.02 patches

With commit '7dedd34: ARM: OMAP2+: hwmod: Fix a crash in _setup_reset()
with DEBUG_LL' we moved from parsing cmdline to identify uart used
for earlycon to using the requsite hwmod CONFIG_DEBUG_OMAPxUARTy FLAGS.
On DRA7 UART3 hwmod doesn't have this flag enabled, and atleast on
BeagleBoard-X15, where we use UART3 for console, boot fails with
DEBUG_LL enabled. Enable DEBUG_OMAP4UART3_FLAGS for UART3 hwmod.
For using DEBUG_LL, enable CONFIG_DEBUG_OMAP4UART3 in menuconfig.

We still have SND_OMAP_SOC_AM3517EVM depending on MACH_OMAP3517EVM,
so let's keep MACH_OMAP3517EVM Kconfig option around for a little
bit longer.
This removes the dependency between ARM SoC changes and the ASoC
changes, and allows the following three options for the driver:
1. Update the driver for device tree based booting
2. Initialize the driver with legacy platform data, then update
the driver for device tree based booting
3. Just remove the driver if there are no audio users for
3517-evm board

Commit 9a1091ef00 ("irqchip: gic: Support hierarchy irq domain")
changed the GIC driver to use a non-legacy IRQ domain on DT
platforms. This patch assumes that DT-driven systems are getting
all of their interrupts from device tree.
Turns out that OMAP has quite a few hidden gems, and still uses
hardcoded interrupts despite having fairly complete DTs.
This patch attempts to work around these by offering a translation
method that can be called directly from the hwmod code, if present.
The same hack is sprinkled over PRCM and TWL.
It isn't pretty, but it seems to do the job without having to add
more hacks to the interrupt controller code.
Tested on OMAP4 (Panda-ES) and OMAP5 (UEVM5432).

Otherwise it will return true for cpu_is_omap34xx() which we don't
want for the clocks and hwmod. It's closer to am33xx for the clocks
and hwmod than to the omap34xx. We also want to be able to detect
814x and 816x separately as at least the clocks are different with
814x using a apll and 816x using a fapll for the source clocks.

If the boot loader enables HYP mode on the boot CPU, the secondary CPU
also needs to call into the ROM to switch to HYP mode before booting.
The firmwares on the omap5 and dra7xx unfortunately do not take care
of this, so it has to be handled by the kernel.
This patch is based on "[PATCH 2/2] ARM: OMAP5: Add HYP mode entry support
for secondary CPUs" by Santosh Shilimkar <santosh.shilimkar@ti.com>,
except this version does not require a compile time CONFIG to control
if it should enable HYP mode or not, it simply does it based on the mode
of the boot CPU, so it works whether the CPU boots in SVC or HYP mode,
and should even work as a guest kernel inside kvm if qemu decides to
support emulating the omap5 or dra7xx.
