[PATCH 5.4 106/152] clk: qcom: gcc: fix sm8150 GPU and NPU clocks

From: Greg Kroah-Hartman
Date: Thu Aug 20 2020 - 08:33:31 EST


From: Jonathan Marek <jonathan@xxxxxxxx>

[ Upstream commit 667f39b59b494d96ae70f4217637db2ebbee3df0 ]

Fix the parents and set BRANCH_HALT_SKIP. From the downstream driver it
should be a 500us delay and not skip, however this matches what was done
for other clocks that had 500us delay in downstream.

Fixes: f73a4230d5bb ("clk: qcom: gcc: Add GPU and NPU clocks for SM8150")
