Subject: [PATCH 0/2] ASoC: Add the NXP TFA9865 amplifier
Date: Mon, 16 Nov 2026 01:50:24 +0530 [thread overview]
Message-ID: <20261116-vantage-tfa9865-v1-0-e88f0dccc427@yahoo.com> (raw)
The Motorola Signature has two NXP (now Goodix) TFA9865 mono class-D
speaker amplifiers. This series adds the devicetree binding and a driver.
The chip has no DSP and a different register map than the TFA989x parts
of tfa989x.c. The driver applies the initialization sequence for the
device revision, selects the I2S slot feeding the amplifier and powers
the amplifier and its boost converter up and down. The register settings
come from the NXP tfa98xx driver. Only the B0 revision and the 32-bit I2S
slots configured at reset are supported for now.
Tested on a Motorola Signature: with the matching sound card the speaker
and the earpiece play audio.
I used an LLM (Claude) to help write these patches and their commit
messages. I reviewed all of them and tested the result on the device.
