Petr Kulhavy 6bce5efd44 ARM: davinci: remove unused davinci-i2s pdata
The davinci-i2s driver ("davinci-mcbsp") does not use platform
data any longer. Remove the dummy pdata provided by the board
drivers dm355, dm365, dm644x and neuros-osd2.

David Lechner 6fc9ebbdeb ARM: davinci: Move clock init after ioremap.
Some clocks (such as the USB PHY clocks in DA8xx) will need to use iomem.
The davinci_common_init() function must be called before the ioremap, so
the clock init is now split out as separate function.

Currently we have one device created to handle all (maximum 2) eDMAs in the

Lad, Prabhakar 9a3e89b10f [media] media: davinci: vpss: enable vpss clocks
By default the VPSS clocks were enabled in capture driver
for davinci family which creates duplicates for dm355/dm365/dm644x.
This patch adds support to enable the VPSS clocks in VPSS driver,
which avoids duplication of code and also adding clock aliases.
This patch uses PM runtime API to enable/disable clock, instead
of DaVinci clock framework. con_ids for master and slave clocks of
vpss is added in pm_domain.
This patch cleanups the VPSS clock enabling in the capture driver,
and also removes the clock alias in machine file. Along side adds
a vpss slave clock for DM365 as mentioned by Sekhar
(https://patchwork.kernel.org/patch/1221261/).
The Suspend/Resume in dm644x_ccdc.c which enabled/disabled the VPSS clock
is now implemented as part of the VPSS driver.

Lad, Prabhakar caff80c35f [media] davinci: vpbe: pass different platform names to handle different ip's
The vpbe driver can handle different platforms DM644X, DM36X and
DM355. To differentiate between this platforms venc_type/vpbe_type
was passed as part of platform data which was incorrect. The correct
way to differentiate to handle this case is by passing different
platform names.
This patch creates platform_device_id[] array supporting different
platforms and assigns id_table to the platform driver, and finally
in the probe gets the actual device by using platform_get_device_id()
and gets the appropriate driver data for that platform.
Taking this approach will also make the DT transition easier.

Linus Torvalds d027db132b ARM: arm-soc: SoC updates for 3.8
This contains the bulk of new SoC development for this merge window.
 
 Two new platforms have been added, the sunxi platforms (Allwinner A1x
 SoCs) by Maxime Ripard, and a generic Broadcom platform for a new
 series of ARMv7 platforms from them, where the hope is that we can
 keep the platform code generic enough to have them all share one mach
 directory. The new Broadcom platform is contributed by Christian Daudt.
 
 Highbank has grown support for Calxeda's next generation of hardware,
 ECX-2000.
 
 clps711x has seen a lot of cleanup from Alexander Shiyan, and he's also
 taken on maintainership of the platform.
 
 Beyond this there has been a bunch of work from a number of people on
 converting more platforms to IRQ domains, pinctrl conversion, cleanup
 and general feature enablement across most of the active platforms.

Lad, Prabhakar e37212aa5d ARM: davinci: dm644x: fix out range signal for ED
Fix the video clock setting when custom timings are used with
pclock <= 27MHz. Existing video clock selection uses PLL2 mode
which results in a 54MHz clock whereas using the MXI mode results
in a 27MHz clock (which is the one actually desired).

This bug affects the Enhanced Definition (ED) support on DM644x.
Without this patch, out-range signals errors are were observed on
the TV when viewing ED. An out-of-range signal is often caused when
the field rate is above the rate that the television will handle.

Linus Torvalds 4f1cd91497 Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull second set of media updates from Mauro Carvalho Chehab:
 "Despite its size, most of the stuff here is trivial.  This series
  contains:

   - s5p-mfc: additions at the driver and at the core to support H.264
     hardware codec;
   - Some improvements at s5p and davinci embedded drivers;
   - Some V4L2 compliance fixes applied on a few drivers;
   - Several random trivial patches, including several fixes and a few
     new board support additions;

  Notes:

   1) Some Exynos media patches were dependent on some -arm fixes that
      got merged on changeset 782cd9e.  That's why this pull request is
      based that changeset.

   2) As promised, I reviewed the pending VB2 DMABUF series.

      While setting a test environment, it was noticed that the upstream
      support for Samsung Exynos 4 boards (smdk310 and Origen) are
      broken upstream, likely due to regressions: both defconfigs are
      wrong and regulator settings for both boards are broken.  That,
      allied with some bug at the dummy regulator driver, causes OOPSes
      during boot time.

      Long story short: even fixing the above, the proposed patches
      OOPSed when running the DMABUF test.  Not sure yet if the OOPSes
      are due to some other undetected regressions, or due to some bug
      on the patches.

      Due to the above, DMABUF patches for vb2 got NACKed for 3.7."

Ido Yariv f23fe857bb ARM: davinci: Explicitly set channel controllers' default queues
Davinci platforms may define a default queue for each channel
controller. If one is not defined, the default queue is set to EVENTQ_1.
However, there's no way to distinguish between an unset default queue to
one that is set to EVENTQ_0, as EVENTQ_0 = 0.

Explicitly specify the default queue for all channel controllers on all
Davinci platforms to EVENTQ_1, and don't overwrite it in the EDMA probe
function.

One exception is the DA850 board, for which EVENTQ_1 is not a valid
option for its second channel controller. Use EVENTQ_0 instead for that
channel controller.
