description: | | ||
The CS4271 requires its LRCLK and MCLK to be stable before its RESET | ||
line is de-asserted. That also means that clocks cannot be changed | ||
without putting the chip back into hardware reset, which also requires | ||
a complete re-initialization of all registers. | ||
One (undocumented) workaround is to assert and de-assert the PDN bit | ||
in the MODE2 register. This workaround can be enabled with this DT | ||
property. | ||
Note that this is not needed in case the clocks are stable | ||
throughout the entire runtime of the codec. | ||
