Can we use fallback to qcom,sa8775p-dp instead of declaring a completely
new one?
I think we can not use fallback to sa8775p, since we don't have DP1
controller for QCS8300. SA8775P actually have 4 DP controllers (now only
2 really used). So in the hardware, i think it is different with SA8775P
and we need a new one.>> - qcom,sa8775p-dp
