  20 Optional properties
  21 - reg-io-width: the width of the reg:1,4, default set to 1 if not present
  22 - ddc-i2c-bus: phandle of an I2C controller used for DDC EDID probing,
  23   if the property is omitted, a functionally reduced I2C bus
  24   controller on DW HDMI is probed
  25 - clocks, clock-names: phandle to the HDMI CEC clock, name should be "cec"
