This is caused by another patch from the original series failing
to apply due to some bulk regulator renaming.  I'll send backported
version of that patch soon, which should make everything fine.


On ARM configs, we do see the same issue that Naresh reported.

Caused by commit: 1e4bd0ec5a47 ("arm64: dts: rockchip: Add missing PCIe supplies to RockPro64 board dtsi") -- PATCH 42/77 of this series.

We see same problem with 6.12.21-rc1 as well.


Notes:
-----
I think Dragan was referring to upstream commit: bd1c959f37f3 ("arm64: dts: rockchip: Add avdd HDMI supplies to RockPro64 board dtsi") which will fix this problem but fails to apply due to regulator renaming in commit: 5c96e6330197 ("arm64: dts: rockchip: adapt regulator nodenames to preferred form") which is not in stable kernels(6.6.y and 6.12.y)


Thanks,
Harshit
