"This has three changes for asm-generic that did not really fit into

architecture independent device drivers.
* The UAPI split patches from David Howells for the asm-generic

through the arch maintainer tree and that depend on this one.
There may be a few small merge conflicts between Mark's patch and the

will be to keep the new "generic-y += clkdev.h" line, even if it ends

Commit eb05f691290e99ee0bd1672317d6add789523c1e ("ARM: OMAP: hwmod:
partially un-reset hwmods might not be properly enabled") added code
to skip the IP block disable sequence if all of the block's hardreset
lines weren't asserted. But this did not handle the case when no
hardreset lines were associated with a module, which is the general
case. In that situation, the IP block disable would be skipped. This
is likely to cause PM regressions.
So, modify _omap4_disable_module() and _am33xx_disable_module() to
only bail out early if there are any hardreset lines asserted. And
move the AM33xx test above the actual module disable code to ensure
that the behavior is consistent.

Commit b71c721 (ARM: OMAP2+: clockdomain/hwmod: add workaround for EMU
clockdomain idle problems) added a workaround for the EMU clock domain on
OMAP3/4 devices to prevent the clock domain for transitioning while it is
in use.
In the proposed patch [1] code was added to the omap3xxx_clkdm_clk_enable()
and omap3xxx_clkdm_clk_disable() functions to check for the flag
CLKDM_MISSING_IDLE_REPORTING and perform the appropriate action. However, in the
merged patch it appears that this code was added to the omap2_clkdm_clk_enable()
and omap2_clkdm_clk_disable() functions by mistake.

git://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-omap-pm into omap-for-v3.7-rc1/fixes-cpufreq
This series a couple bug fixes and a couple fixes that make this
driver support recently added OMAP-based SoCs.
The 'get_cpu_device' patch is needed due to a change in the OMAP
OMAP PM core code which enforces use of get_cpu_device() instead of
a deprecated OMAP-specific API.
The usage of plat/*.h headers breaks single zImage, so platforms are
cleaning up and/or removing plat/*.h so the driver needs to be fixed
accordingly.
This series is based on the merge of Rafael's pm-for-3.7-rc1 tag into
Linus' master branch: commit 16642a2e7be23bbda013fc32d8f6c68982eab603.

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"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."

Currently, a dummy omap_device is created for the MPU sub-system so
that a device node exists for MPU DVFS. Specifically, for the
association of MPU OPPs to a device node, and so that a voltage
regulator can be mapped to a device node.
For drivers to get a handle to this device node, an OMAP-specific API
has been used. However, the kernel already has device nodes for the
CPU(s) in the system, so we can use those instead of an OMAP-specific
dummy device and then drivers (like OMAP CPUfreq) can use generic
APIs.
To use the existing CPU device nodes, modify the OPP creation and
regulator registration to use the CPU0 device node for registraion.
NOTE: this patch always uses CPU0 as the device node. On all
OMAPs today, MPU DVFS scales all CPUs together, so this will
not be a problem, but this assumption will need to be changed
if independently scalable CPUs are introduced.

memblock_steal tries to reserve physical memory during boot.
When the requested size is not aligned on the section size
then, the remaining memory available for lowmem becomes
unaligned on the section boundary. There is a issue with this,
which is discussed in the thread below.

The final conclusion from the thread seems to
be align the memblock_steal calls on the SECTION boundary.
The issue comes out when LPAE is enabled, where the
section size is 2MB.
Boot tested this on OMAP5 evm with and without LPAE.

read_persistent_clock uses a global variable, use a spinlock to
ensure non-atomic updates to the variable don't overlap and cause
time to move backwards.

task_work_run() implementation had the side effect of enabling
interrupts. With commit ac3d0da8 (task_work: Make task_work_add()
lockless), interrupts are no longer enabled revealing the bug in the
arch code. This patch enables the interrupt explicitly before calling
do_notify_resume().

The generic implementation of compat_sys_sendfile() has been introduced
by commit 8f9c0119. This patch removes the arm64 implementation in
favour of the generic one.

Following commit 74838b7 (swiotlb: add the late swiotlb initialization
function with iotlb memory) the swiotlb_init_with_default_size() is a
static function. This patch changes the arm64 code to call
swiotlb_init() instead and use the default size of 64MB. It is assumed
that AArch64 platforms have enough RAM to afford the pre-allocated
swiotlb memory. It also removes the #ifdef around this call since
CONFIG_SWIOTLB is always enabled.

In case of error, the function clk_register() returns ERR_PTR()
no NULL pointer. The NULL test in the return value check should
be replaced with IS_ERR().

This patch implements DMA support into mxs-i2c. DMA transfers are now enabled
via DT. The DMA operation is enabled by default.

On mx35pdk board there is an 8-bit microcontroller that controls several IOs, such
as backlight enable pin, USB host VBUS, etc.
Let it build by default.
mx35pdk also needs CONFIG_LCD_PLATFORM to be selected to activate the display,
so also make this the default.

In case of error, the function ioremap() returns NULL
not ERR_PTR(). The IS_ERR() test in the return value
check should be replaced with NULL test.
