tlv320dac31xx is a subset of tlv320aic31xx: - it does not have MIC inputs and ADC, thus capture is not supported, - it has analog inputs AIN1/AIN2 that can be mixed into output. Although tlv320dac31xx does work with tlv320aic31xx driver, this setup does register non-existent widgets and non-existent capture stream. Thus userspace lists non-existent objects in user interfaces, an can access these, causing operations with device registers that are declared as "reserved" in tlv320dac31xx datasheet. This patch fixes this situation by separating controls/widgets/routes into common, aic31xx-specific, and dac31xx-specific parts. Only parts that match actual hardware (as declared in "compatible" device tree property) are registered. Changes from v1: - update device tree binding documentation, - rebased on top of "ASoC: codec duplicated callback function goes to component on tlv320aic31xx" commit.

CODEC output pins:
|
|
* HPL
|
|
* HPR
|
|
* SPL, devices with stereo speaker amp
|
|
* SPR, devices with stereo speaker amp
