[PATCH v6 04/10] clk: qcom: branch: Clean up branch enable registers
From: Konrad Dybcio
Date: Wed Feb 08 2023 - 04:15:47 EST
Prefix the "branch enable" registers with CBCR_ to be closer to what
they are actually called in Qualcomm terms, use GENMASK instead of
shifting values around and adjust their usage accordingly.
