Subject: [PATCH v1 0/2] ASoC: codecs: add Texas Instruments TAS2557 smart amplifier driver
Date: Fri, 10 Jul 2026 00:13:27 +0200 [thread overview]
Message-ID: <20260709221331.989109-1-morf3089@gmail.com> (raw)
The TAS2557 is a mono Class-D smart amplifier with an on-chip DSP for
speaker protection, controlled over I2C with audio carried over
I2S/TDM. The DSP requires a board-specific firmware image generated
with TI's PurePath Console tuning tools; without it the device passes
no audio.
Patch 1 adds the devicetree binding. Patch 2 adds the ASoC codec
driver: mono and dual-device stereo operation, per-device ti,channel
tuning, and fault-interrupt recovery that reloads the firmware
configuration on clock loss, over-current, brownout or
over-temperature.
Tested in mono configuration on Xiaomi Mi A2 (SDM660, jasmine),
Xiaomi Redmi Note 6 Pro (SDM636, tulip) and Xiaomi Redmi 5 Plus
(MSM8953, vince), driving the top speaker, and in dual-device stereo
configuration on Xiaomi Mi Pad 4 (SDM660, clover).
Based on v7.2-rc1.
