[PATCH v2 2/9] clk: qcom: gcc-sdm660: Mark GPU CFG AHB clock as critical

From: AngeloGioacchino Del Regno
Date: Wed Jan 13 2021 - 13:39:46 EST


This clock is critical for any access to the GPU: gating it will
crash the system when the GPU has been initialized (so, you cannot
gate it unless you deinit the Adreno completely).

So, to achieve a working state with GPU on, set the CLK_IS_CRITICAL
flag to this clock.
