Add driver for the internal audio codec of the Rockchip RK3308 SoC. Initially based on the vendor kernel driver [0], with lots of cleanups, fixes, improvements, conversion to DAPM and removal of some features. [0] https://github.com/rockchip-linux/kernel/blob/develop-4.19/sound/soc/codecs/rk3308_codec.c Signed-off-by: Luca Ceresoli <luca.ceresoli@bootlin.com> --- Changed in v4: - use devm_reset_control_get_optional_exclusive() instead of devm_reset_control_get() - cleanup probe by using a 'dev' variable - reword some error messages - rename static structs for clarity - remove unnecessary array in declaration of dai_driver - use clk_bulk* calls for clock initialization Changed in v3: - fix silent playback until a given amplitude of sigital value, seen at >= 96 kHz rate - simplify capture setup by removing unneeded loop - use unsigned char for codec version - cleanup a few register defines - remove unused enums and defines - update copyright year Changed in v2: - convert everything to DAPM support - move rk3308_codec_power_on/off() code to .set_bias_level - move MICBIAS setting from hw_params to probe - support silicon version C which differs in some registers - removed LINE IN code as LINE IN is not supported by the hardware - remove unneeded digital reset in in rk3308_codec_hw_params - rewrite on/off controls to be bool switches, not enums - fix _put() operations return value (1 if value changed) - fix RK3308_ADC_CURRENT_CHARGE_MSK power-down ramp (it was ramping up just like the power-up ramp) - enable zero-cross detection unconditionally - Remove AGC/ALC implementation - Add HPF controls (enable and cut-off frequency) - model HP output as a stereo control (requires new ASoC helper macro) - use ADC_CH*_MIC_MUTE for muting mics, not the BIST bits - fix uninitialized variable is_master - remove useless wrappers - remove .mute_stream callback - remove digital fade in/out for HPOUT volume - remove many unneeded register initializations to their reset values and documented the few places where open-coded initializations to values different from the reset value are needed - collapse various functions into rk3308_codec_adc_dig_config(), which simplified dramatically the hw_params code - various coding style and comments improvements, code reorganization - add error checking in several places --- MAINTAINERS | 2 + sound/soc/codecs/Kconfig | 11 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/rk3308_codec.c | 974 ++++++++++++++++++++++++++++++++++++++++ sound/soc/codecs/rk3308_codec.h | 579 ++++++++++++++++++++++++ 5 files changed, 1568 insertions(+)
