ASoC: dt-bindings: Add documentation for the Cirrus CS4334 stereo codec (d730e205) · Commits · 戴 / test

The Cirrus CS4334 is a 16-24 bit stereo DAC with I2S input. It does not have any management interface (like I2C, SPI, GPIOs, etc.). A functionally compatible replacement is the MXT8234 from Beijing Times Minxin Technology Co., Ltd. Add the dt-bindings and a compatible string for the Cirrus and Beijing Times Minxin Technology Co., Ltd. variant. The latter is just a safety measure in case any differences to the actual CS4334 codec are found. Signed-off-by:
