[PATCH 12/25] ASoC: meson: t9015: add support for A1 SoC family

From: Jan Dakinevich <hidden>
Date: 2024-03-14 23:23:09
Also in: alsa-devel, linux-amlogic, linux-clk, linux-devicetree, linux-gpio, linux-sound, lkml
Subsystem: arm/amlogic meson soc sound drivers, sound, sound - soc layer / dynamic audio power management (asoc), the rest · Maintainers: Jerome Brunet, Jaroslav Kysela, Takashi Iwai, Liam Girdwood, Mark Brown, Linus Torvalds

A1's internal codec is very close to t9015. The main difference, that it
has ADC. This commit introduces support for capturing from it.
