[PATCH v2 1/2] ARM: at91: dts: add isi & ov2640 dt nodes for at91sam9m10g45ek board
From: Josh Wu
Date: Tue Jun 16 2015 - 06:05:26 EST
First we group the isi data pins, and for now we only use 0~7 data pins
with HSYNC and VSYNC.
Also add the link for atmel-isi and ov2640 sensor node.
Signed-off-by: Josh Wu <josh.wu@xxxxxxxxx>

Changes in v2:
- group the isi data pin.
- remove the isi_mck pin from pinctrl-isi as it will used by camera
sensor.
