[PATCH 0/3] arm64: dts: qcom: UFS updates

[Vinod Koul]

We recently saw regression on UFS on SM8150 and few other boards and that
was resolved by adding timeout and fixing the UFS phy reset sequence. That
patches are in linux-next now.

During this we found sm8150 lacks gpio reset for ufs, so add that and fix
the ufs phy register size.
Also add the sdm845 ufs reset.
