[alsa-devel] ASoC: pll/clkdiv issue with simple-card driver & WM8510/Atmel SSC

Implementing such a feature into simple-card driver alone might not be possible, as the PLL output frequency and resulting MCLK/BCLK divisors are codec dependent.

I wonder if the right place would be within the codec driver, after all? The machine code would just request a certain bitclock frequency and frame length in case the codec is selected to be the clock master.

Is this in line with ASoC architecture?
