Subject: [PATCH 415/773] ASoC: tlv320aic32x4: Add Playback PowerTune Controls
|
|
|
|
commit d3e6e374566e1154820a9a3dc82f7eef646fcf95 upstream.
|
|
|
|
PowerTune controls the power level of the chip. On playback this
|
|
indirectly controls things like the gain of the various output
|
|
amplifiers. This can allow for the decrease of output levels
|
|
from the codec. This adds controls for those power levels to
|
|
the driver.
