> TI's AM62 SoC can optionally provide two audio reference clocks
> (AUDIO_REFCLKx) to external peripherals.
> 
> By default this reference clock is looped-back inside the SoC to a mux
> that goes to McASP AHCLK, but can optionally be enabled as an output to
> peripherals outside the SoC by setting a bit through CTRL_MMR registers.
> 
> This bit only controls the direction of the clock, while the parent
> is a muxed input from sci-clk [1] which may be a configurable PLL or a
> master clock from one of the McASP instances.
