[PATCH V2 2/2] ASoC: max98396: add amplifier driver

Ryan Lee ryan.lee.analog at gmail.com
Fri Apr 22 01:02:53 CEST 2022


This series of patches adds support for Analog Devices MAX98396
mono amplifier with IV sense. The device provides a PCM interface
for audio data and a standard I2C interface for control data
communication. This driver also supports MAX98397 which is
a variant of MAX98396 with wide input supply range.

  Changes from v1:
    : Fixed DAI format configuration issue. BCLK/FRSYNC polarity configuration
    was inappropriate.
    : max98396_mux_put function return 1 if the value changed. Otherwise
    the function return 0 or -EINVAL;
    : Modified wrong amp POR(Power On Register) value in max98396_reg.
