[PATCH v2 07/18] clk: qcom: gcc-sm4450: Set delay for Venus CLK resets

From: Konrad Dybcio
Date: Tue Feb 06 2024 - 13:45:37 EST


Some Venus resets may require more time when toggling. Describe that.

The value was obtained on a best-guess basis: msm-5.4 being the base
kernel for this SoC and 4450 being somewhat close to 8350 which is known
to require a higher delay [1].
