[alsa-devel] [PATCH 0/2] ASoC: tlv320aic31xx: Optimize the master mode I2S clock handling

Hi,

Instead of forcing DAC/ADC to be turned on, we can use P0 R29, Bit2 to let the I2S clocks running, but we do not want it to run all the time and we do not want I2S clocks when it is not needed (analog loopback mode).

Use DAPM_SUPPLY for the bit and connect it to the in/out AIF.

The DAPM routes can be modify to not include the DAC/ADC.
