Did Zubair write this glue driver? He's been MIA for a while, doesn't work at ImgTec anymore, and this email doesn't work.

- The HDMI Transmitter in the Ingenic JZ4780 is a Synopsys
DesignWare HDMI 1.4
- TX controller IP with accompanying PHY IP.

- $ref: panel/panel-common.yaml#
+properties:
- compatible:
- items:
- const: ingenic,jz4780-hdmi- reg:
- maxItems: 1
- description: the address & size of the LCD controller registers
Remove the description here,
- reg-io-width:
- const: 4
- interrupts:
- maxItems: 1
- description: Specifies the interrupt provided by parent
and here.
The rule is that if there is only one "reg", "interrupts" or "clocks" entry then a description is not needed as it's pretty obvious what it's for.
- clocks:
- maxItems: 2
- description: Clock specifiers for isrf and iahb clocks
You need two 'description:' like this:
clocks: items: - description: ISRF clock - description: IAHB clock
Cheers, -Paul
