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
