A specialisation of the generic Synopsys HDMI driver is employed for
JZ4780
HDMI support. This requires a new driver, plus device tree and
configuration
modifications.

I *think* this should go to the board file.

The JZ4780's LCD controller is much newer than the JZ4740 one, so even
if it works with the "ingenic,jz4740-lcd" compatible string, you want
it as a fallback.
So this should be: compatible = "ingenic,jz4780-lcd",
"ingenic,jz4740-lcd".
That means the YAML should be updated too.
