Как будто бы вместе с этим патчем надо брать изменения на binding'и[1],
иначе в dtbs_check появляются новые ошибки:

arch/arm64/boot/dts/edelweiss/rk3588-thin_88rk-1a-001.dtb: spdif-tx at fddb0000 (rockchip,rk3588-spdif): compatible: 'oneOf' conditional failed, one must be fixed:
	['rockchip,rk3588-spdif', 'rockchip,rk3568-spdif'] is too long
	'rockchip,rk3066-spdif' was expected
	'rockchip,rk3228-spdif' was expected
	'rockchip,rk3328-spdif' was expected
	'rockchip,rk3366-spdif' was expected
	'rockchip,rk3368-spdif' was expected
	'rockchip,rk3399-spdif' was expected
	'rockchip,rk3568-spdif' was expected
	'rockchip,rk3588-spdif' is not one of ['rockchip,rk3128-spdif', 'rockchip,rk3188-spdif', 'rockchip,rk3288-spdif', 'rockchip,rk3308-spdif']
	from schema $id: http://devicetree.org/schemas/sound/rockchip-spdif.yaml


Однако я вижу, что по традиции при бекпортировании патчей на dts(i) такого
не происходило, и это кажется достаточно разумным, так как изменения
в bindings могут приводить к конфликтам при merge (как и любые изменения),
а на функциональность они не влияют.

Если по этому поводу другие мнения?
