73   ddc-i2c-bus:
76       Some panels expose EDID information through an I2C-compatible
77       bus such as DDC2 or E-DDC. For such panels the ddc-i2c-bus contains a
78       phandle to the system I2C controller connected to that bus.

129   power-supply:
131       Display panels require power to be supplied. While several panels need
132       more than one power supply with panel-specific constraints governing the
133       order and timings of the power supplies, in many cases a single power
134       supply is sufficient, either because the panel has a single power rail, or
135       because all its power rails can be driven by the same supply. In that case
136       the power-supply property specifies the supply powering the panel as a
142   # controller exposed through a control bus such as I2C or DSI. Others expose
144   # backlight controller.
150       controller, this property contains a phandle that references the
151       controller.
