Correct dts node name in patch v1: performance-domain
This patch depends on [1] and [2].
[1]http://lists.infradead.org/pipermail/linux-mediatek/2020-November/019378.html
[2]https://patchwork.kernel.org/project/linux-mediatek/patch/1607586516-6547-3-git-send-email-hector.yuan@xxxxxxxxxxxx/
Those two series are now merged, so no dependencies missing for this patch any
longer.
Please rebase this patch, as there are some conflicts. I've already verified it,
and after you rebase I can send a reviewed-by.
Thanks,
Nícolas

Actually there is a warning being introduced here on dtbs_check:
soc: 'performance-controller@0011bc00' does not match any of the regexes: '@(0|[1-9a-f][0-9a-f]*)$', '^[^@]+$', 'pinctrl-[0-9]+'
From schema: [...]/dtschema/schemas/simple-bus.yaml
So you should also change the address to not start with zeros: 11bc00
Thanks,
