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

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

Daniel Beer (2):
  ASoC: add support for TAS5805M digital amplifier
  ASoC: dt-bindings: add bindings for TI TAS5805M.
