+- ddc-i2c-bus: phandle of the I2C controller used for DDC EDID probing
+- gpio-controller: Marks the device has a GPIO controller. +- #gpio-cells : Should be two. The first cell is the pin number and
the second cell is used to specify flags.See ../../gpio/gpio.txt for more information.+- #pwm-cells : Should be one. See ../../pwm/pwm.txt for description of
the cell formats.+- clock-names: should be "refclk" +- clocks: Specification for input reference clock. The reference
clock rate must be 12 MHz, 19.2 MHz, 26 MHz, 27 MHz or 38.4 MHz.+- lane-mapping: Specification to describe the logical to physical lane
As I mentioned in v7, we already have a property for this. It's called 'data-lanes' and defined in media/video-interfaces.txt. Use that. If you need polarity too, then add a property for that. And add it to video-interfaces.txt.
Looks like inversion is already handled by the 'lane-polarities' property.
