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
