Hello.
Here's the set of 4 patches against the Simon Horman's 'renesas.git' repo,
'renesas-next-20130417' tag and my recent yet unapplied patches. Here we
add the VIN (Video In) driver and its platform code working on the R8A7779/
Marzen with ADV7180 I2C camera sensor. The driver patch also applies without
issues to Mauro's 'media_tree.git'...
[1/4] V4L2: soc_camera: Renesas R-Car VIN driver
[2/4] ARM: shmobile: r8a7779: add VIN support
[3/4] ARM: shmobile: Marzen: add VIN and ADV7180 support
[4/4] ARM: shmobile: Marzen: enable VIN and ADV7180 in defconfig
WBR, Sergei
