Quoting Daniel Mack (2022-01-25 01:33:33)
> The CS2000 chip features two input clocks, REF_CLK and CLK_IN.
>
> In static mode, the output clock (CLK_OUT) is directly derived from
> REF_CLK, and CLK_IN is ignored. In dynamic mode, CLK_IN is used by the
> digital PLL.
>
> In dynamic mode, a low-frequency ratio configuration that uses a higher
> multiplier factor.
>
> Until now, only the static mode and high-frequency divider rations of
> the hardware was supported by the driver. This patch adds support for
> dynamic mode and both ratios:
>
> * Parse a new OF property 'cirrus,dynamic-mode' to determine the mode
> * In dynamic mode, present CLK_IN as parent clock, else use REF_CLK
> * The low-frequency ratio mode is automatically selected, depending
> on the mode of operation and the given input and output rates
