From: Sam Ravnborg sam@ravnborg.org Add DT bindings for the LCD controller on the jz4780 SoC Based on .txt binding from Zubair Lutfullah Kakakhel
If you mean Documentation/devicetree/bindings/display/ingenic,lcd.txt then it was written by me.
Ah, ok. We didn't recognise this before. 6 eyes see more than 4...
I just did cherry-pick this old 4.0 patch from 2015 by Zubair and it created a ingenic-jz4780-lcd.txt:
https://lore.kernel.org/patchwork/patch/547872/
and Sam was so kind to convert it to yaml.

+maintainers:
- Zubair Lutfullah Kakakhel Zubair.Kakakhel@imgtec.com
- H. Nikolaus Schaller hns@goldelico.com
I'm the author of the driver, please put me here; and remove Zubair, which 1. didn't touch the DRM driver at all, and 2. isn't working at ImgTec anymore.
Yes that is true.
Also, no need to put yourself here, unless you maintain the Ingenic DRM/KMS driver.
Agreed. That was suggested by Sam.

- LCD Controller is the Display Controller for the Ingenic JZ4780 SoC
+properties:
You should add a '$nodename' property.
- compatible:
- items:
- const: ingenic,jz4780-lcd
The .txt lists more compatible strings. Please add them all.
- reg:

Drop the description here,
- interrupts:

- description: Specifies the interrupt provided by parent
and here.
- clocks:
- maxItems: 2
- description: Clock specifiers for the JZ4780_CLK_TVE JZ4780_CLK_LCD0PIXCLK
Add one 'description:' per item.
- clock-names:
- items:
- const: lcd_clk
- const: lcd_pixclk
- port:
- type: object

A port node with endpoint definitions as defined in

- compatible
- reg
- interrupts
- clocks
- clock-names

+additionalProperties: false
+examples:

- #include <dt-bindings/clock/jz4780-cgu.h>
- lcd: jz4780-lcdk@0x13050000 {
The node name does not comply with the DT spec, it should be 'lcd-controller'.
Ok, I think I'll review all so that it does match/replace Documentation/devicetree/bindings/display/ingenic,lcd.txt and no information is lost.
Cheers, -Paul
BR and thanks, Nikolaus
