DT bindings using the graph binding must have references to the graph binding schema. These are missing from the adi,adv7511 and adi,adv7533 bindings, so add them.

The ADV7533 and ADV7535 are HDMI audio and video transmitters
|
|
compatible with HDMI 1.4 and DVI 1.0. They support color space
|
|
conversion, S/PDIF, CEC and HDCP. The transmitter input is MIPI DSI.

I2C slave addresses.
|
|
|
|
The ADV7533/35 internal registers are split into four pages
|
|
exposed through different I2C addresses, creating four register
|
|
maps. Each map has it own I2C address and acts as a standard slave
|
|
device on the I2C bus. The main address is mandatory, others are
|
|
optional and revert to defaults if not specified.
