To understand what happens, here is the relevant section of the clock tree (slightly simplified), along with the names used in the driver: vpll0 _OR_ vpll1 "mclk_root" clk_i2s2_8ch_tx_src "mclk_parent" clk_i2s2_8ch_tx_mux clk_i2s2_8ch_tx "mclk" or "mclk_tx" This is what happens when playing back e.g. at 192 kHz using audio-graph-card (when recording the same applies, only s/tx/rx/): 0. at probe, rockchip_i2s_tdm_set_sysclk() stores the passed frequency in i2s_tdm->mclk_tx_freq (*) which is 50176000, and that is never modified afterwards 1. when playback is started, rockchip_i2s_tdm_hw_params() is called and does the following two calls 2. rockchip_i2s_tdm_calibrate_mclk(): 2a. selects mclk_root0 (vpll0) as a parent for mclk_parent (mclk_tx_src), which is OK because the vpll0 rate is a good for 192000 (and sumbultiple) rates 2b. sets the mclk_root frequency based on ppm calibration computations 2c. sets mclk_tx_src to 49152000 (= 256 * 192000), which is also OK as it is a multiple of the required bit clock 3. rockchip_i2s_tdm_set_mclk() 3a. calls clk_set_rate() to set the rate of mclk_tx (clk_i2s2_8ch_tx) to the value of i2s_tdm->mclk_tx_freq (*), i.e. 50176000 which is not a multiple of the sampling frequency -- this is not OK 3a1. clk_set_rate() reacts by reparenting clk_i2s2_8ch_tx_src to vpll1 -- this is not OK because the default vpll1 rate can be divided to get 44.1 kHz and related rates, not 192 kHz The result is that the driver does a lot of ad-hoc decisions about clocks and ends up in using the wrong parent at an unoptimal rate. Step 0 is one part of the problem: unless the card driver calls set_sysclk at each stream start, whatever rate is set in mclk_tx_freq during boot will be taken and used until reboot. Moreover the driver does not care if its value is not a multiple of any audio frequency. Another part of the problem is that the whole reparenting and clock rate setting logic is conflicting with the CCF algorithms to achieve largely the same goal: selecting the best parent and setting the closest clock rate. And it turns out that only calling once clk_set_rate() on clk_i2s2_8ch_tx picks the correct vpll and sets the correct rate. The fix is based on removing the custom logic in the driver to select the parent and set the various clocks, and just let the Clock Framework do it all. As a side effect, the set_sysclk() op becomes useless because we now let the CCF compute the appropriate value for the sampling rate. It also implies that the whole calibration logic is now dead code and so it is removed along with the "PCM Clock Compensation in PPM" kcontrol, which has always been broken anyway. The handling of the 4 optional clocks also becomes dead code and is removed. The actual rates have been tested playing 30 seconds of audio at various sampling rates before and after this change using sox: time play -r -n synth 30 sine 950 gain -3 The time reported in the table below is the 'real' value reported by the 'time' command in the above command line. rate before after --------- ------ ------ 8000 Hz 30.60s 30.63s 11025 Hz 30.45s 30.51s 16000 Hz 30.47s 30.50s 22050 Hz 30.78s 30.41s 32000 Hz 31.02s 30.43s 44100 Hz 30.78s 30.41s 48000 Hz 29.81s 30.45s 88200 Hz 30.78s 30.41s 96000 Hz 29.79s 30.42s 176400 Hz 27.40s 30.41s 192000 Hz 29.79s 30.42s While the tests are running the clock tree confirms that: * without the patch, vpll1 is always used and clk_i2s2_8ch_tx always produces 50176000 Hz, which cannot be divided for most audio rates except the slowest ones, generating inaccurate rates * with the patch: - for 192000 Hz vpll0 is used - for 176400 Hz vpll1 is used - clk_i2s2_8ch_tx always produces (256 * ) Hz Tested on the RK3308 using the internal audio codec. Fixes: 081068fd6414 ("ASoC: rockchip: add support for i2s-tdm controller") Signed-off-by: Luca Ceresoli --- As discussed after v3, the clock manipulation logic that this patch removes is a remnant of the downstream 4.19 driver (https://github.com/rockchip-linux/kernel/blob/develop-4.19/sound/soc/rockchip/rockchip_i2s_tdm.c). It might be that the CCF was not yet capable of optimally reparenting back in 4.19, so it did make sense back then. Changed in v4: - Mention the tested hardware in the commit message - No content changes Changed in v3: - this patch is new in v3, and it replaces and supersedes the patch "ASoC: rockchip: i2s-tdm: Fix clk_id usage in .set_sysclk()" --- sound/soc/rockchip/rockchip_i2s_tdm.c | 352 +--------------------------------- 1 file changed, 6 insertions(+), 346 deletions(-) diff --git a/sound/soc/rockchip/rockchip_i2s_tdm.c b/sound/soc/rockchip/rockchip_i2s_tdm.c index 860e66ec85e8..9fa020ef7eab 100644 --- a/sound/soc/rockchip/rockchip_i2s_tdm.c +++ b/sound/soc/rockchip/rockchip_i2s_tdm.c @@ -25,8 +25,6 @@ #define DEFAULT_MCLK_FS 256 #define CH_GRP_MAX 4 /* The max channel 8 / 2 */ #define MULTIPLEX_CH_MAX 10 -#define CLK_PPM_MIN -1000 -#define CLK_PPM_MAX 1000 #define TRCM_TXRX 0 #define TRCM_TX 1 @@ -53,20 +51,6 @@ struct rk_i2s_tdm_dev { struct clk *hclk;

Add one that does that. Note that even though the snd_soc_*_volsw_range() look more appropriate given the _range suffix, they are not suitable because they don't honor the two shift values. The snd_soc_*_volsw() look more generic and are suitable for the task.

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 --- 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(+) diff --git a/MAINTAINERS b/MAINTAINERS index 9c5ef9219086..94b5ecc7c9d7 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -18944,6 +18944,8 @@ ROCKCHIP RK3308 INTERNAL AUDIO CODEC M: Luca Ceresoli S: Maintained F: Documentation/devicetree/bindings/sound/rockchip,rk3308-codec.yaml +F: sound/soc/codecs/rk3308_codec.c +F: sound/soc/codecs/rk3308_codec.h ROCKCHIP VIDEO DECODER DRIVER M: Ezequiel Garcia diff --git a/sound/soc/codecs/Kconfig b/sound/soc/codecs/Kconfig index 59f9742e9ff4..1c9d671a9848 100644 --- a/sound/soc/codecs/Kconfig +++ b/sound/soc/codecs/Kconfig @@ -179,6 +179,7 @@ config SND_SOC_ALL_CODECS imply SND_SOC_PCM512x_I2C imply SND_SOC_PCM512x_SPI imply SND_SOC_PEB2466 + imply SND_SOC_RK3308 imply SND_SOC_RK3328 imply SND_SOC_RK817 imply SND_SOC_RT274 @@ -1400,6 +1401,16 @@ config SND_SOC_PEB2466 To compile this driver as a module, choose M here: the module will be called snd-soc-peb2466. +config SND_SOC_RK3308 + tristate "Rockchip RK3308 audio CODEC" + select REGMAP_MMIO + help + This is a device driver for the audio codec embedded in the + Rockchip RK3308 SoC. + + It has 8 24-bit ADCs and 2 24-bit DACs.
