Pull media updates from Mauro Carvalho Chehab:
- Two new dvb frontend drivers: mn88472 and mn88473
- A new driver for some PCIe DVBSky cards
- A new remote controller driver: meson-ir
- One LIRC staging driver got rewritten and promoted to mainstream:
igorplugusb
- A new tuner driver (m88rs6000t)
- The old omap2 media driver got removed from staging. This driver
uses an old DMA API and it is likely broken on recent kernels.
Nobody cared enough to fix it
- Media bus format moved to a separate header, as DRM will also use the
definitions there
- mem2mem_testdev were renamed to vim2m, in order to use the same
naming convention taken by the other virtual test driver (vivid)
- Added a new driver for coda SoC (coda-jpeg)
- The cx88 driver got converted to use videobuf2 core
- Make DMABUF export buffer to work with DMA Scatter/Gather and Vmalloc
cores
- Lots of other fixes, improvements and cleanups on the drivers.

The GPMC driver has traditionally been considered a part of the
OMAP platform code and tightly interweaved with some of the boards.
With this cleanup, it has finally come to the point where it makes
sense to move it out of arch/arm into drivers/memory, where we already
have other drivers for similar hardware. The cleanups are still
ongoing, with the goal of eventually having a standalone driver
that does not require an interface to architecture code.
This is a separate branch because of dependencies on multiple other
branches, and to keep the drivers changes separate from the normal
cleanups.

Note that we now also remove the omap specific check for the

Also the postcore_initcall() maybe possible to change to
just regular module_init(), but let's do that in separate

The omap2 camera driver has been deprecated for a year and is now
going to be removed. It is unmaintained and it uses an internal API
that has long since been superseded by a much better API. Worse, that
internal API has been abused by out-of-kernel trees (i.MX6).
In addition, Sakari stated that these drivers have never been in a
usable state in the mainline kernel due to missing platform data.

Omap4 and later have been booting in device tree only
mode for quite some time now. This initcall is no longer
needed. Note that omap3 uses a different driver omap_l3_smx,
and the initcall for that one is still needed until omap3
boots in device tree only mode.
Signed-off-by: Tony Lindgren <tony@atomide.com>
When booting omap3 in device tree mode, we're currently getting
the following errors:
omap_l3_smx omap_l3_smx.0: couldn't request debug irq
omap_l3_smx: probe of omap_l3_smx.0 failed with error -22
This is because we don't have handling in the driver for the
compatible property and instead assume platform data being
passed.
Note that this binding is already documented, and implemented
for the related omap_l3_noc driver for omap4 and later. Looks
like the binding somehow never got never implemented for this
omap_l3_smx driver though.
Let's also remove __exit_p to allow binding and unbinding
of the driver while at it.

that, there are a few things to point out:
- Lots of platform conversion on OMAP2+, with removal of old board files

- Final conversion of a bunch of ux500 (ST-Ericsson) platforms as well
- Some updates to pinctrl and other subsystems. Most of these are for

These changes are all driver specific and cross over between arm-soc
contents and some other subsystem, in these cases cpufreq, crypto,
dma, pinctrl, mailbox and usb, and the subsystem owners agreed to
have these changes merged through arm-soc. As we proceed to untangle
the dependencies between platform code and driver code, the amount of
changes in this category is fortunately shrinking, for 3.11 we have
16 branches here and 101 non-merge changesets, the majority of which
are for the stedma40 dma engine driver used in the ux500 platform.
Cleaning up that code touches multiple subsystems, but gets rid
of the dependency in the end.
The mailbox code moved out from mach-omap2 to drivers/mailbox
is an intermediate step and is still omap specific at the moment.
Patches exist to generalize the subsystem and add other drivers
with the same API, but those did not make it for 3.11.
Conflicts:
* In cpu-db8500.c results from the removal of the u8500_of_init_devices
function in combination with the split of u8500_auxdata_lookup.
* In arch/arm/mach-omap2/devices.c, the includes got reshuffled.
we need to keep linux/wl12xx.h and linux/platform_data/mailbox-omap.h.

Merge tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC driver specific changes from Arnd Bergmann:
"These changes are all driver specific and cross over between arm-soc
contents and some other subsystem, in these cases cpufreq, crypto,
dma, pinctrl, mailbox and usb, and the subsystem owners agreed to have
these changes merged through arm-soc.
As we proceed to untangle the dependencies between platform code and
driver code, the amount of changes in this category is fortunately
shrinking, for 3.11 we have 16 branches here and 101 non-merge
changesets, the majority of which are for the stedma40 dma engine
driver used in the ux500 platform. Cleaning up that code touches
multiple subsystems, but gets rid of the dependency in the end.
The mailbox code moved out from mach-omap2 to drivers/mailbox is an
intermediate step and is still omap specific at the moment. Patches
exist to generalize the subsystem and add other drivers with the same
API, but those did not make it for 3.11."

Most notable here is the removal of support for ATAGS based OMAP4
systems. Since all OMAP4 machines are fully functional with DT based
booting in 3.10, we can remove a lot of code here.
Also noteworthy is Maxime Ripard's cleanup of the machine descriptors,
which means we need no machine descriptors in a lot more cases and

The mailbox hardware (in OMAP) uses a queued mailbox interrupt
mechanism that provides a communication channel between processors
through a set of registers and their associated interrupt signals
by sending and receiving messages.
The OMAP mailbox framework/driver code is moved to be under
drivers/mailbox, in preparation for adapting to a common mailbox
driver framework. This allows the build for OMAP mailbox to be
enabled (it was disabled during the multi-platform support).
As part of the migration from plat and mach code:
- Kconfig symbols have been renamed to build OMAP1 or OMAP2+ drivers.
- mailbox.h under plat-omap/plat/include has been split into a public
and private header files. The public header has only the API related
functions and types.
- The module name mailbox.ko from plat-omap is changed to
omap-mailbox.ko
- The module name mailbox_mach.ko from mach-omapX is changed as
mailbox_omap1.ko for OMAP1
mailbox_omap2.ko for OMAP2+

The OMAP mailbox platform driver code has been cleaned up to
remove the dependencies with soc.h in preparation for moving
the mailbox code to drivers folder.
The code relied on cpu_is_xxx/soc_is_xxx macros previously to
pick the the right set of mailbox devices and register with the
mailbox driver. This data is now represented in a concise format
and moved to the respective omap_hwmod data files and published
to the driver through the platform data.

- 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)

Merge branch 'omap/multiplatform-fixes', tag 'v3.8-rc5' into next/multiplatform
The omap multiplatform support uncovered a bug in the cwdavinci_cpdma
code and was missing two drivers that are enabled now but are not
quite ready for multiplatform, as found by allyesconfig builds.
There is also a conflict generated by automated merge in
arch/arm/mach-omap2/drm.c between a bug fix that went into v3.8-rc5
and a different version of the same fix that went into the
omap/multiplatform branch. This merge removes the extraneous
#include that was causing build errors.
* omap/multiplatform-fixes:
net: cwdavinci_cpdma: export symbols for cpsw
remoteproc: omap: depend on OMAP_MBOX_FWK
[media] davinci: do not include mach/hardware.h

Commit c1d1cd597f ("ARM: OMAP2+:
omap_device: remove obsolete pm_lats and early_device code") missed a
few omap_device_build() calls that aren't included as part of the default
OMAP2+ Kconfig, omap2plus_defconfig.
Ideally, all devices that are present on the SoC should be created by
default, and only the corresponding device driver should be configured
or deconfigured in Kconfig. This allows drivers to be built as
modules and loaded later, even if they weren't part of the original
kernel build. Unfortunately, we're not quite there yet.
Thanks to Tony Lindgren for reporting this, found during his
randconfig tests.

A seperate driver has been added to handle the usb part of control
module. A device for the above driver is created here, using the register
address information to be used by the driver for powering on the PHY and
for writing to the mailbox.
