Hello.

   Here's the set of 5 patches against the Simon Horman's 'renesas.git' repo,
'renesas-next-20130422' tag and my recent yet unapplied patches. Here we
add the OKI ML86V7667 video decoder driver and the VIN platform code working on
the R8A7778/BOCK-W with ML86V7667. The driver patch also applies (with offsets)
to Mauro's 'media_tree.git'...

[1/5] V4L2: I2C: ML86V7667 video decoder driver
[2/5] sh-pfc: r8a7778: add VIN pin groups
[3/5] ARM: shmobile: r8a7778: add VIN support
[4/5] ARM: shmobile: BOCK-W: add VIN and ML86V7667 support
[5/5] ARM: shmobile: BOCK-W: enable VIN and ML86V7667 in defconfig

WBR, Sergei

Add OKI Semiconductor ML86V7667 video decoder driver.

Signed-off-by: Vladimir Barinov <vladimir.barinov@cogentembedded.com>
[Sergei: added v4l2_device_unregister_subdev() call to the error cleanup path of
ml86v7667_probe(); some cleanup.]

Changes since version 2:
- removed now unused #include;
- fixed querystd() method to return currently detected video standard;
- switched from using V4L2_STD_[PAL|NTSC] to using V4L2_STD_[625_50|525_60].

Changes since the original posting:
- fixed ACCC_CHROMA_CB_MASK;
- got rid of the autodetection feature;
- removed querystd() method calls from other methods;
- removed deprecated g_chip_ident() method.

Add VIN clocks and platform devices on R8A7778 SoC; add function to register
the VIN platform devices.

Signed-off-by: Vladimir Barinov <vladimir.barinov@cogentembedded.com>
[Sergei: added 'id' parameter check to r8a7779_add_vin_device(), used '*pdata'
in *sizeof* operator there, renamed some variables, annotated 'vin[01]_info' and
vin[01]_resources[] as '__initdata'.]
Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>

---
Changes from version 2:
- annotated 'vin[01]_info' and vin[01]_resources[] as '__initdata' since they're
  kmemdup()'ed while registering the platform devices anyway;
- refreshed the patch.

     It turned out that VIN1 signal VI1_CLK conflicts with Ether signal 
ETH_REF_CLK.
So I'm a bit at a loss here: whether I should totally remove VIN1 device 
if I'm going
to add Ether device, or add a BOCK-W specific submenu to Kconfig, or add 
driver
specific #ifdef's in the code to disable VIN1 if sh_eth driver is 
enabled?...

WBR, Sergei

My preference, in order is:

* Remove VIN1 (is it used?)
* Kconfig-foo
* #ifdef nastiness
