Subject: [PATCH v2 0/2] ASoC: add support for TAS5805M digital amplifier
Date: Thu, 13 Jan 2022 21:38:41 +1300 [thread overview]
Message-ID: <cover.1642063121.git.daniel.beer@igorinstitute.com> (raw)
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
