[PATCH v2 0/4] ASoC: Add TAS675x quad-channel Class-D amplifier driver

[Sen Wang]

This series adds support for the TI TAS675x (TAS6754, TAS67524)
quad-channel automotive Class-D amplifiers. The devices have an
integrated DSP and load diagnostics, and are controlled over I2C.

Patch 1 adds the dt-binding, patch 2 the codec driver, patch 3 the
ALSA mixer controls documentation, and patch 4 adds the MAINTAINERS
entry.

Tested on AM62D-EVM with a TAS67CD-AEC daughter card, on setups &
test procedures, refer to the Github repository.

Changes in v2:
 - Remove redundant DAPM event function (2/4)
 - Move IRQ request past power_on, so regs can be set in a clean state (2/4)
 - Add delayed_work at probe time to accomdate no PM configs (2/4)
 - Change .set_fmt and .dapm_routes callbacks to the same tas675x_set_fmt name (1/3)
