92702df357 ARM: OMAP4: PM: fix PM regression introduced by recent clock cleanup
Commit 17b7e7d335 ("ARM: OMAP4:
clock/hwmod data: start to remove some IP block control "clocks"")
introduced a regression preventing the L3INIT clockdomain of OMAP4
systems from entering idle.  This in turn prevented these systems from
entering full chip clock-stop.

The regression was caused by the incorrect removal of a so-called
"optional functional clock" from the OMAP4 clock data.  This wasn't
caught for two reasons.  First, I missed the retention entry failure
in the branch test logs:

http://www.pwsan.com/omap/testlogs/cleanup_a_3.9/20130126014242/pm/4460pandaes/4460pandaes_log.txt

Second, the integration data for the OCP2SCP PHY IP block, added by
commit 0c6688753f ("ARM: OMAP4: hwmod
data: add remaining USB-related IP blocks"), should have associated this
clock with the IP block, but did not.

Fix by adding back the so-called "optional" functional clock to the
clock data, and by linking that clock to the OCP2SCP PHY IP block
integration hwmod data.

The problem patch was discovered by J, Keerthy <j-keerthy@ti.com>.

7307c00f33 arm-soc: late OMAP changes
This branch contains changes for OMAP that came in late during the release
 staging, close to when the merge window opened.
 
 It contains, among other things:
 
 - OMAP PM fixes and some patches for audio device integration
 - OMAP clock fixes related to common clock conversion
 - A set of patches cleaning up WFI entry and blocking.
 - A set of fixes and IP block support for PM on TI AM33xx SoCs (Beaglebone, etc)
 - A set of smaller fixes and cleanups around AM33xx restart and revision
   detection, as well as removal of some dead code (CONFIG_32K_TIMER_HZ)

This version also changes the AESS main clock to use a

Enable the AESS auto-gating control bit during AESS hwmod setup.  This
fixes the following boot warning on OMAP4:

omap_hwmod: aess: _wait_target_disable failed

Without this patch, the AESS IP block does not indicate to the PRCM
that it is idle after it is reset.  This prevents some types of SoC
power management until something sets the auto-gating control bit.

787314c35f IOMMU Updates for Linux v3.8
A few new features this merge-window. The most important one is
 probably, that dma-debug now warns if a dma-handle is not checked with
 dma_mapping_error by the device driver. This requires minor changes to
 some architectures which make use of dma-debug. Most of these changes
 have the respective Acks by the Arch-Maintainers.
 Besides that there are updates to the AMD IOMMU driver for refactor the
 IOMMU-Groups support and to make sure it does not trigger a hardware
 erratum.
 The OMAP changes (for which I pulled in a branch from Tony Lindgren's
 tree) have a conflict in linux-next with the arm-soc tree. The conflict
 is in the file arch/arm/mach-omap2/clock44xx_data.c which is deleted in
 the arm-soc tree. It is safe to delete the file too so solve the
 conflict. Similar changes are done in the arm-soc tree in the common
 clock framework migration. A missing hunk from the patch in the IOMMU
 tree will be submitted as a seperate patch when the merge-window is
 closed.

  changes have the respective Acks by the Arch-Maintainers.

  Besides that there are updates to the AMD IOMMU driver for refactor
  the IOMMU-Groups support and to make sure it does not trigger a
  hardware erratum.

  The OMAP changes (for which I pulled in a branch from Tony Lindgren's
  tree) have a conflict in linux-next with the arm-soc tree.  The
  conflict is in the file arch/arm/mach-omap2/clock44xx_data.c which is
  deleted in the arm-soc tree.  It is safe to delete the file too so
  solve the conflict.  Similar changes are done in the arm-soc tree in
  the common clock framework migration.  A missing hunk from the patch
  in the IOMMU tree will be submitted as a seperate patch when the
  merge-window is closed."

This branch contains a largeish set of updates of power management and

 It includes a split-up of some of the OMAP clock data into separate

from enabling modulemode inside CLKCTRL using its clk->enable_reg

the one in charge of this setting.

According to comments received[1] for related patches the idea is
to get rid of leaf clocks in future. So remove these two while at it.

45c3eb7d3a ARM: OMAP: Move plat-omap/dma-omap.h to include/linux/omap-dma.h
Based on earlier discussions[1] we attempted to find a suitable
location for the omap DMA header in commit 2b6c4e73 (ARM: OMAP:
DMA: Move plat/dma.h to plat-omap/dma-omap.h) until the conversion
to dmaengine is complete.

Unfortunately that was before I was able to try to test compile
of the ARM multiplatform builds for omap2+, and the end result
was not very good.

So I'm creating yet another all over the place patch to cut the
last dependency for building omap2+ for ARM multiplatform. After
this, we have finally removed the driver dependencies to the
arch/arm code, except for few drivers that are being worked on.

The other option was to make the <plat-omap/dma-omap.h> path
to work, but we'd have to add some new header directory to for
multiplatform builds.

Or we would have to manually include arch/arm/plat-omap/include
again from arch/arm/Makefile for omap2+.

Neither of these alternatives sound appealing as they will
likely lead addition of various other headers exposed to the
drivers, which we want to avoid for the multiplatform kernels.

Since we already have a minimal include/linux/omap-dma.h,
let's just use that instead and add a note to it to not
use the custom omap DMA functions any longer where possible.

Note that converting omap DMA to dmaengine depends on
dmaengine supporting automatically incrementing the FIFO
address at the device end, and converting all the remaining
legacy drivers. So it's going to be few more merge windows.

Merge tag 'v3.7-rc7' into next/cleanup

Merging in mainline back to next/cleanup since it has collected a few
conflicts between fixes going upstream and some of the cleanup patches.
Git doesn't auto-resolve some of them, and they're mostly noise so let's
take care of it locally.

Conflicts are in:

10759e823c ARM: OMAP2+: Don't use __omap_dm_timer_reset()
Currently OMAP2+ devices are using the function __omap_dm_timer_reset() to
configure the clock-activity, idle, wakeup-enable and auto-idle fields in the
timer OCP_CFG register. The name of the function is mis-leading because this
function does not actually perform a reset of the timer.

For OMAP2+ devices, HWMOD is responsible for reseting and configuring the
timer OCP_CFG register. Therefore, do not use __omap_dm_timer_reset() for
OMAP2+ devices and rely on HWMOD. Furthermore, some timer instances do not
have the fields clock-activity, wakeup-enable and auto-idle and so this
function could configure the OCP_CFG register incorrectly.

Currently HWMOD is not configuring the clock-activity field in the OCP_CFG
register for timers that have this field. Commit 0f0d080 (ARM: OMAP: DMTimer:
Use posted mode) configures the clock-activity field to keep the f-clk enabled
so that the wake-up capability is enabled. Therefore, add the appropriate flags
to the timer HWMOD structures to configure this field in the same way.

For OMAP2/3 devices all dmtimers have the clock-activity field, where as for
OMAP4 devices, only dmtimer 1, 2 and 10 have the clock-activity field.

Verified on OMAP2420 H4, OMAP3430 Beagle and OMAP4430 Panda that HWMOD is
configuring the dmtimer OCP_CFG register as expected for clock-events timer.

Most of the prototypes in plat-omap/common.h are not

The only shared function prototype in this file is
omap_init_clocksource_32k(), let's put that into
counter-32k.h.

Note that the new plat/counter-32k.h must not be
included from drivers, that will break omap2+ build

bc05244e65 ARM: OMAP4: hwmod data: do not enable or reset the McPDM during kernel init
Resolve this kernel boot message:

omap_hwmod: mcpdm: cannot be enabled for reset (3)

The McPDM on OMAP4 can only receive its functional clock from an
off-chip source.  This source is not guaranteed to be present on the
board, and when present, it is controlled by I2C.  This would
introduce a board dependency to the early hwmod code which it was not
designed to handle.  Also, neither the driver for this off-chip clock
provider nor the I2C code is available early in boot when the hwmod
code is attempting to enable and reset IP blocks.  This effectively
makes it impossible to enable and reset this device during hwmod init.

At its core, this patch is a workaround for an OMAP hardware problem.
It should be possible to configure the OMAP to provide any IP block's
functional clock from an on-chip source.  (This is true for almost
every IP block on the chip.  As far as I know, McPDM is the only
exception.)  If the kernel cannot reset and configure IP blocks, it
cannot guarantee a sane SoC state.  Relying on an optional off-chip
clock also creates a board dependency which is beyond the scope of the
early hwmod code.

This patch works around the issue by marking the McPDM hwmod record
with the HWMOD_EXT_OPT_MAIN_CLK flag.  This prevents the hwmod
code from touching the device early during boot.

f5a246eab9 Sound updates for 3.7-rc1
This contains pretty many small commits covering fairly large range of
 files in sound/ directory.  Partly because of additional API support
 and partly because of constantly developed ASoC and ARM stuff.
 
 Some highlights:
 
 - Introduced the helper function and documentation for exposing the
   channel map via control API, as discussed in Plumbers; most of PCI
   drivers are covered, will follow more drivers later
 
 - Most of drivers have been replaced with the new PM callbacks (if
   the bus is supported)
 
 - HD-audio controller got the support of runtime PM and the support of
   D3 clock-stop.  Also changing the power_save option in sysfs kicks
   off immediately to enable / disable the power-save mode.
 
 - Another significant code change in HD-audio is the rewrite of
   firmware loading code.  Other than that, most of changes in HD-audio
   are continued cleanups and standardization for the generic auto
   parser and bug fixes (HBR, device-specific fixups), in addition to
   the support of channel-map API.
 
 - Addition of ASoC bindings for the compressed API, used by the
   mid-x86 drivers.
 
 - Lots of cleanups and API refreshes for ASoC codec drivers and
   DaVinci.
 
 - Conversion of OMAP to dmaengine.
 
 - New machine driver for Wolfson Microelectronics Bells.
 
 - New CODEC driver for Wolfson Microelectronics WM0010.
 
 - Enhancements to the ux500 and wm2000 drivers
 
 - A new driver for DA9055 and the support for regulator bypass mode.

 - A number of cleanup series for OMAP, moving and removing some
   headers, sparse irq rework and in general preparation for
   multiplatform.
 - Final removal of all non-DT boards for Tegra, it is now
   device-tree-only!
 - Removal of a stale platform, nxp4008. It's an old mobile chipset
   that is no longer in use, and was very likely never really used with
   a mainline kernel. We have not been able to find anyone interested
   in keeping it around in the kernel.
 - Removal of the legacy dmaengine driver on tegra

Merge tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM soc general cleanups from Olof Johansson:
 "This is a large branch that contains a handful of different cleanups:

   - Fixing up the I/O space remapping on PCI on ARM.  This is a series
     from Rob Herring that restructures how all pci devices allocate I/O
     space, and it's part of the work to allow multiplatform kernels.
   - A number of cleanup series for OMAP, moving and removing some
     headers, sparse irq rework and in general preparation for
     multiplatform.
   - Final removal of all non-DT boards for Tegra, it is now
     device-tree-only!
   - Removal of a stale platform, nxp4008.  It's an old mobile chipset
     that is no longer in use, and was very likely never really used
     with a mainline kernel.  We have not been able to find anyone
     interested in keeping it around in the kernel.
   - Removal of the legacy dmaengine driver on tegra

  + A handful of other things that I haven't described above."

Fix up some conflicts with the staging tree (and because nxp4008 was
removed)

76a5d9bfc4 ARM: OMAP4460/4470: PMU: Enable PMU for OMAP4460/70
OMAP4460 and OMAP4470 devices have dedicated PMU interrupts and so add these
interrupts to the MPU HWMOD so we can use these for PMU events on these
devices. The PMU interrupts need to be the first interrupts in the array of
interrupts as the ARM PMU driver assumes this.

By using these dedicated interrupts we only need to enable the MPU and DEBUG
sub-systems for PMU to work. This is different to OMAP4430 that did not have
dedicated interrupts and required other power domains in addition to the DEBUG
sub-system to be enabled so we could route the PMU events to the CTI interrupts.
Hence, OMAP4460 and OMAP4470 devices can use the same list of HWMODs to create
the PMU device that is using by OMAP3.

5c3e4ec485 ARM: OMAP: Add a timer attribute for timers that can interrupt the DSP
Some instances of the DMTIMER peripheral on OMAP devices have the ability
to interrupt the on-chip DSP in addition to the ARM CPU. Add a DMTIMER
attribute to indicate which timers can interrupt the DSP. By using the
omap_dm_timer_request_by_cap() API, driver will now be able to allocate
a DMTIMER that can interrupt the DSP based upon this attribute and not require
the driver to know which instance has this capability.

DMTIMERs that have the ability to interrupt the DSP on OMAP devices are as
follows ...

- OMAP1 (OMAP5912/16xx/17xx) devices	- All 8 DMTIMERs
- OMAP2/3/4 devices			- DMTIMERs 5-8

Please note that for OMAP3+, timer8 has the ability to interrupt the DSP and
generate a PWM output.

ce80979aed ARM: OMAP4: hwmod data: add support for lostcontext_mask
Currently hwmod only provides the offset for the context lose
register, and if we attempt to share the same register between two or
more hwmods, the resulting context loss counts get wrong. Thus, we
need a way to specify which bits are used for the context loss
information for each.  This is accomplished by adding a new field to
the omap4 prcm struct, 'lostcontext_mask', which specifies a bit-mask
to use for filtering the register.

Mark the affected hwmods appropriately.  'l4_abe' hwmod uses the
LOSTMEM_AESSMEM bit of RM_ABE_AESS_CONTEXT register, as l4_abe doesn't
have its own dedicated register for this purpose. This register is
shared with 'aess' hwmod, thus both hwmods must also specify which
bits of the register are used for them.

This patch only adds the hwmod data, but a future patch should add
code support such that only the specified bits are read and cleared by
the context lose counter update code. If a hwmod doesn't specify
'lostcontext_mask' (default behavior), the whole contents of the
context register should be used without any filtering.

dbc0416104 ARM: OMAP: Split plat/hardware.h, use local soc.h for omap2+
As the plat and mach includes need to disappear for single zImage work,
we need to remove plat/hardware.h.

Do this by splitting plat/hardware.h into omap1 and omap2+ specific files.

The old plat/hardware.h already has omap1 only defines, so it gets moved
to mach/hardware.h for omap1. For omap2+, we use the local soc.h
that for now just includes the related SoC headers to keep this patch more
readable.

Note that the local soc.h still includes plat/cpu.h that can be dealt
with in later patches. Let's also include plat/serial.h from common.h for
all the board-*.c files. This allows making the include files local later
on without patching these files again.

Note that only minimal changes are done in this patch for the
drivers/watchdog/omap_wdt.c driver to keep things compiling. Further
patches are needed to eventually remove cpu_is_omap usage in the drivers.

Also only minimal changes are done to sound/soc/omap/* to remove the
unneeded includes and to define OMAP44XX_MCPDM_L3_BASE locally so there's
no need to include omap44xx.h.

While at it, also sort some of the includes in the standard way.

The OMAP4 usb_host_fs (OHCI) and AESS IP blocks require some special
programming for them to enter idle.  Without this programming, they
will prevent the rest of the chip from entering full chip idle.

To implement the idle programming cleanly, this will take some
coordination between maintainers.  This is likely to take some time,
so it is probably best to leave this for 3.6 or 3.7.  So, in the
meantime, prevent these IP blocks from being registered.

Later, once the appropriate support is available, this patch can be
reverted.

This second version comments out the IP block data since Benoît didn't
like removing it.

As per the OMAP4 documentation, audio over HDMI must be transmitted in
no-idle mode. This patch adds the HWMOD_SWSUP_SIDLE so that omap_hwmod uses
no-idle/force-idle settings instead of smart-idle mode.

This is required as the DSS interface clock is used as functional clock
for the HDMI wrapper audio FIFO. If no-idle mode is not used, audio could
be choppy, have bad quality or not be audible at all.

414e41286e ARM: OMAP2+: WDTIMER integration: fix !PM boot crash, disarm timer after hwmod reset
Without runtime PM enabled, hwmod needs to leave all IP blocks in an
enabled state by default so any driver access to the HW will succeed.
This is accomplished by seting the postsetup_state to enabled for all
hwmods during init when runtime PM is disabled.

Currently, we have a special case for WDT in that its postsetup_state
is always set to disabled.  This is done so that the WDT is disabled
and the timer is disarmed at boot in case there is no WDT driver.
This also means that when runtime PM is disabled, if a WDT driver *is*
built in the kernel, the kernel will crash on the first access to the
WDT hardware.

We can't simply leave the WDT module enabled, because the timer is
armed by default after reset. That means that if there is no WDT
driver initialzed or loaded before the timer expires, the kernel will
reboot.

To fix this, a custom reset method is added to the watchdog class of
omap_hwmod.  This method will *always* disarm the timer after hwmod
reset.  The WDT timer then will only be rearmed when/if the driver is
loaded for the WDT.  With the timer disarmed by default, we no longer
need a special-case for the postsetup_state of WDT during init, so it
is removed.

Any platforms wishing to ensure the watchdog remains armed across the
entire boot boot can simply disable the reset-on-init feature of the
watchdog hwmod using omap_hwmod_no_setup_reset().

Tested on 3530/Overo, 4430/Panda.

NOTE: on 4430, the hwmod OCP reset does not seem to rearm the timer as
documented in the TRM (and what happens on OMAP3.)  I noticed this
because testing the HWMOD_INIT_NO_RESET feature with no driver loaded,
I expected a reboot part way through the boot, but did not see a
reboot.  Adding some debug to read the counter, I verified that right
after OCP softreset, the counter is not firing.  After writing the
magic start sequence, the timer starts counting.  This means that the
timer disarm sequence added here does not seem to be needed for 4430,
but is technically the correct way to ensure the timer is disarmed, so
it is left in for OMAP4.

Special thanks to Paul Walmsley for helping brainstorm ideas to fix
this problem.

844a3b632b ARM: OMAP2+: hwmod data: remove forward declarations, reorganize
Reorganize the hwmod data to declare the IP blocks first and the
interconnects second.  This allows us to remove the forward
declarations, which this patch also does. Saves some lines of source
data.  While here, take the opportunity to synchronize the order of
the OMAP44xx hwmod data with the autogenerator output -- it's slightly
different due to past mismerges -- and fix a few minor typos and
whitespace problems in the files.

0a78c5c596 ARM: OMAP2+: hwmod data: convert to link registration
Register interconnect links between IP blocks, rather than the IP
blocks themselves.  (The IP blocks will be registered as a side-effect
of registering the links.)

The objective is to reduce the number of lines of static data and
facilitate the sharing of IP block data between different SoCs.  These
objectives come at the penalty of increased boot time due to increased
computation.

While here, fix a few whitespace problems and inaccurate variable names.

53c4c6c37c ARM: OMAP4: hwmod data: uncomment some "excluded" hwmods
Some hwmods were commented out from the OMAP4 data, under the theory
that they shouldn't be added until drivers were ready.  But part of
the utility of the hwmod code is that it can reset and properly
initialize IP blocks that have no drivers associated with them.
Rather than commenting the links in the future hwmod data conversion
patches, discussing this with Benoit, it seems best to simply
uncomment them now.

3d10f0d6d9 ARM: OMAP4: hwmod data: add OCP_USER_DSP; mark omap44xx_dsp__iva appropriately
One of the OMAP4 links was missing OCP_USER flags, since it was only
used by the DSP initiator, and we did not have an OCP_USER_DSP flag.
Future patches will switch the hwmod code and data to register
interfaces, rather than hwmods, and it will be mandatory for all
interfaces to have at least one user bit set.  This patch resolves the
issue by adding OCP_USER_DSP and marking the DSP-IVA interface
appropriately.

8291113f82 ARM: OMAP4: hwmod data: remove bandgap hwmod
Commit 407a6888f7 ("OMAP4: hwmod data:
Add AESS, McPDM, bandgap, counter_32k, MMC, KBD, ISS & IPU") adds a
hwmod for the bandgap die temperature sensor IP block.  This IP block
has no interconnect port or firewall region, nor does it have an
independent register space or OCP control registers.  Its registers
are embedded in the System Control Module (SCM) IP block.  So it
appears that the bandgap device should be created by the SCM driver.

f2f5736cf8 ARM: OMAP4: hwmod data: remove pseudo-hwmods associated with hardreset lines
Remove the pseudo-hwmods associated with hardreset lines from the
OMAP4 data file.  Future patches will convert this data to register
hwmods by interfaces, rather than registering hwmods directly.  The
pseudo-hwmods aren't associated with any interfaces, so this will
create a problem.

After this change, the hwmod code will reset processor IPs at the
hwmod level, rather than by individual hardreset lines.  So, for
example, if the IVA device driver code wishes to place one of the
sequencer cores into reset, while leaving the other active, it must do
so itself by calling the appropriate PRM functions.

This patch will cause a change in the initialization behavior of the
DSP, IVA, and IPU.
