Subject: [PATCH v3 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 v2 as follows:

  - The redundant mutex has been removed
  - DSP configuration is loaded as a firmware image, rather than
    directly from the device-tree
  - The volume control returns non-zero when the values have changed, as
    required
  - Some corrections to device-tree example

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