Subject: Re: [PATCH 4/4] clk: qcom: gcc-msm8916: Add rates to the GP clocks

Quoting Nikita Travkin (2021-12-09 08:37:20)
> msm8916 has (at least) 6 "General Purpose" clocks that can be muxed to
> SoC pins. These clocks are:
> 
> GP_CLK{0, 1} : GPIO_{31, 32} (Belongs to CAMSS according to Linux)
> GP_CLK_{1-3}{A, B} : GPIO_{49-51, 97, 12, 13} (Belongs to GCC itself)
> GP_MN : GPIO_110 (Doesn't seem to be described in gcc,
>     ignored in this patch)
> 
> Those clocks may be used as e.g. PWM sources for external peripherals.
> Add more frequencies to the table for those clocks so it's possible
> for arbitrary peripherals to make use of them.
