Series arm64: qcom: set of fixes for SM8350 platform | expand

Commit Message

Dmitry Baryshkov Aug. 4, 2024, 5:40 a.m. UTC 
The msm-5.x kernels have additional display RSC and separate display BCM
voter. Since upstream kernel doesn't yet provide display RSC, we end up
duplicating several nodes, which can result in incorrect votes being
cast. Drop *_DISP nodes.

Fixes: fafc114a468e ("interconnect: qcom: Add SM8450 interconnect provider driver")
