Thank you so much, so can I use something like this
display:
$ref: /schemas/types.yaml#/definitions/phandle
description: A phandle pointing to the display node.
patternProperties:
"^panel":
type: object
properties:
atmel,dmacon:
atmel,lcdcon2:
:
:
required:
- atmel,dmacon
- atmel,lcdcon2
- atmel,guard-time
- bits-per-pixel
additionalProperties: false
I tested it by removing the required property in the panel node and it
flagged it as an issue.
