[PATCH] arm64: dts: mediatek: mt8195: Fix dtbs_check error for tphy

Posted by Macpaul Lin 1 month, 2 weeks ago

The u3phy1 node in mt8195.dtsi was triggering a dtbs_check error.
The error message was:
  t-phy@11e30000: 'power-domains' does not match any of the regexes:
    '^(usb|pcie|sata)-phy@[0-9a-f]+$', 'pinctrl-[0-9]+'
Fix this issue by dropping 'power-domains' of u3phy1 node.

Apart from this, can you or Chunfeng confirm if we should make a
similar change for MT8188[1]?

According to the suggestion and discussion in

I think adding 'power-domains' to PCIE node of MT8188 is okay.

Thanks

You should also mention why this fix is correct from a hardware viewpoint,
i.e. why removing the power domain won't break the device.
