[PATCH/RFT,2/3] ARM: dts: da850-evm.dts: add mt9v032 camera sensor

Commit Message

Kevin Hilman June 2, 2017, 11:44 p.m. UTC

Add nodes to support camera input via UI board connector. Includes;

- i2c-mux used to connect VPIF input peripherals

- camera-sensor on the On-Semi camera board[1], which provides
  and aptina,mt9v032 sensor.  Note that this board provides
  a way to change the i2c addr via a switch, and this series
  assumes 0x4c

- clock-controler for the master clock provided to camera.  Note that
  this node is FYI only.  The upstream driver for ti,cdce913 requires
  CCF, which davinci does not support, so a subsequent patch/hack
  will create a basic clock driver so the camera driver can work

- VPIF endpoint nodes to connect VPIF input and camera sensor

- GPIO hog changes to switch VPIF input from composite to camera
