         * 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 the
         * following flag.
         * Note that this is not needed in case the clocks are stable
         * throughout the entire runtime of the codec.
