[PATCH v2 0/2] ASoC: add support for TAS5805M digital amplifier

From: Daniel Beer
Date: Thu Jan 13 2022 - 03:41:23 EST


This pair of patches implements support for the TAS5805M class D audio
amplifier. This driver, and the example configuration in the device-tree
file, were originally based on a 4.19 series kernel and have been
modified slightly from the tested version.

This resubmission differs from the first as follows:

- Some explanatory comments and constants have been introduced
- The volume control allows L/R to be set independently
- gpiod is used, and regmap is used directly
- .trigger is used instead of DAPM to coordinate DSP boot
- The component is manually registered after power-on, and explicitly
deregistered prior to power-off
- Corrections have been made to the bindings file

ASoC: dt-bindings: add bindings for TI TAS5805M.
