[PATCH 1/2] ASoC: dt-bindings: Add NXP TFA9865 amplifier

[Venkat Yadlapati via B4 Relay <devnull+venkat.yadlapati.yahoo.com@kernel.org>]

From: Venkat Yadlapati <venkat.yadlapati@yahoo.com>

The TFA9865 is a mono class-D speaker amplifier with a boost converter
and voltage/current sensing but no DSP. It is controlled over I2C and
receives audio over I2S/TDM.

An LLM was used to help write this commit message.
