[PATCH 5/8] clk/qcom: sdm845: add register map for simple gate clocks
Caleb Connolly

Tue Oct 24 22:23:56 CEST 2023
Many gate clocks can be enabled with a single register write, add support
for defining these simple gate clocks and add the ones found on SDM845.
While we're here, inline clk_init_uart() into msm_set_rate().
