Commit Message

Vinod Koul May 30, 2023, 4:24 p.m. UTC
Commit 45a3ec891370 ("PCI: qcom: Add sc8180x compatible") added sc8180x
compatible and commit 075a9d55932e ("dt-bindings: PCI: qcom: Convert to
YAML") converted the description to yaml

But there are still some errors specific to sc8180x which this change
attempts to fix. The clocks and resets for sc8180 pcie controller are
different so need to be documented separately

I don't get what's the error here to fix. The clocks you list are
already there as part of oneOf.

It was listed with sm8150 block which has different set of clocks than
used in sc81880x, so this needs to have its own block of clocks and
resets

Ah, after careful check I see indeed difference in one clock.
