Subject: [PATCH 0/4] Prepare general purpose clocks on msm8916
Date: Thu, 9 Dec 2021 21:37:16 +0500 [thread overview]
Message-ID: <20211209163720.106185-1-nikita@trvn.ru> (raw)
Some devices make use of general purpose clocks as PWM outputs by
controlling their duty cycle.
Notably, many devices (e.g. Samsung A3/A5, LG G Watch R and probably
many others) use clock based PWM to control the haptic feedback,
some other can control backlight or flash/torch LED brightness.
As a follow-up to a proposed clock based PWM output driver [1],
this series contains various fixes to make it useful on msm8916
based devices.

clk: qcom: clk-rcg2: Fail Duty-Cycle configuration if MND divider is
not enabled.
clk: qcom: clk-rcg2: Make sure to not write d=0 to the NMD register
pinctrl: qcom: msm8916: Allow CAMSS GP clocks to be muxed
clk: qcom: gcc-msm8916: Add rates to the GP clocks
