This is the initial amplifier driver for max98390. Reported-by: kbuild test robot <lkp@intel.com> Signed-off-by: Steve Lee <steves.lee@maximintegrated.com> --- Changes since V5: * Fixed warning message reported by kbuild. * Finalize default register value. * Update missed AMP_EN register setting during dsm_init. * Modified SPDEX header style. Changes since V4: * Revert return calibration status in max98390_dsm_calib_get: There is no need to return calibration status in get function because there is mixer control lock protecting mixer control access. And set function of DSM calib finishes calibration synchronously. * Fix sprintf in max98390_dsm_init func: Use snprintf to avoid any unreasonable value from DMI. Changes since V3: * Add operation at max98390_dsm_calib_get: Add cal_running variable at max98390_priv structure Add return cal_running at max98390_dsm_calib_get Update cal_running value during calibration * Update max98390_dsm_init func Add dsm_param bin name can select upon vendor and product name. Changes since V2: * Removed warn massage in max98390_dsm_calib_get func and add comment. Changes since V1: * Updated according to Mark's comments. * Updated according to Tzung-Bi's comments. * Removed Enum structure and use TLV data for Volume control sound/soc/codecs/Kconfig | 5 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/max98390.c | 1041 +++++++++++++++++++++++++++++++++++ sound/soc/codecs/max98390.h | 663 ++++++++++++++++++++++ 4 files changed, 1711 insertions(+) create mode 100644 sound/soc/codecs/max98390.c create mode 100644 sound/soc/codecs/max98390.h
