[PATCH 1/3] clk: qcom: gcc-sm8150: Register QUPv3 RCGs for DFS on SM8150
Posted by Satya Priya Kakitapalli 1 year, 11 months ago 
QUPv3 clocks support DFS and thus register the RCGs which require
support for the same.

Fixes: 2a1d7eb854bb ("clk: qcom: gcc: Add global clock controller driver for SM8150")

Can these be const?
