[PATCH linux-next] dt-bindings: usb: snps,dwc3: correct i.MX8MQ support

From: Peng Fan (OSS) <hidden>
Date: 2023-03-20 02:02:24

From: Peng Fan <peng.fan@nxp.com>

The previous i.MX8MQ support breaks rockchip,dwc3 support,
so use select to restrict i.MX8MQ support and avoid break others.

This is not a reason to make your compatible undocumented. You basically
revert your patch. It does not make any sense to me.

You should only need a select, however most likely selecting also
snps,dwc3 (without specific compatible). Anyway this binding - including
how it is referenced by others - is getting unmanagable. I think I
commented about this on some other occasion. The point is that no one
refactors it thus it grows and grows leading to more of such tricky
scenarios.

How it should be refactored? Probably just like all other with re-usable
components: common part and device specific bindings including it. While
snps,dwc3 alone should not be allowed anymore.

Best regards,
Krzysztof

components: common part and device specific bindings including it. While
snps,dwc3 alone should not be allowed anymore.
Thanks, I may take rockchip,dwc3.yaml or other vendor,dwc3.yaml as
reference to introduce fsl-imx8mq,dwc3.yaml to just add a select, and
drop the fsl,imx8mq-dwc3 compatible from snps,dwc3.yaml.

Thanks,
Peng.
Best regards,
Krzysztof
