Subject: ARM: shmobile: silk: add VIN0/ADV7180 DT support
X-Git-Url: http://git.efficios.com/?p=deliverable%2Flinux.git;a=commitdiff_plain;h=8614daf299cbab2bcada922e727fdc9ad45b2412

ARM: shmobile: silk: add VIN0/ADV7180 DT support

Define  the  SILK board dependent part of the  VIN0  device  node.
Add the device node for Analog Devices ADV7180 video decoder to I2C1 bus.
Add the necessary subnodes to interconnect VIN0 and ADV7180 devices.

Based on the Henninger VIN0/ADV8170 device tree patch by myself.
