[alsa-devel] [PATCH v4] ASoC: Add support for Maxim Integrated MAX98927 Amplifier

Signed-off-by: Ryan Lee ryans.lee@maximintegrated.com ---

Changes since v4: * Removed support for SND_SOC_DAIFMT_CBS_CFM. * Fixed coding style for indention. * Removed variables if it has only one user. * Assigned ch_size directly. * Removed oring. * Put the return false in the switch statement. * Removed 'Monomix Output' and 'Speaker Source' controls. * Modified control names per control-names.rst. * Moved Revision ID check code to i2c_probe function. * Added 'Current Limit' control. * Removed 'devm__kfree' function.

Changes since v3: * Combined MAX98926 and MAX98927 binding. Kept existing property name.

Changes since v2: * Removed local register read/write function to avoid duplication of ASoC core function.
