[PATCH v7 0/6] Add cs42l43 PC focused SoundWire CODEC
by Charles Keepax 31 Jan '24

31 Jan '24

This patch chain adds support for the Cirrus Logic cs42l43 PC focused SoundWire CODEC. The chain is currently based of Lee's for-mfd-next branch. This series is mostly just a resend keeping pace with the kernel under it, except for a minor fixup in the ASoC stuff.

[v3 0/3] ASoC: mediatek:mt8186: fix both the speaker and hdmi
by Jiaxin Yu 31 Jan '24

The speaker and hdmi of mt8186 platform are shared the same port of I2S, when connect the external display, use build-in speakers to play audio, they both playback at the same time. So we want to manage the playback device through DAPM events.

ALSA-LIB: xrun recovery in iec958 plugin for 8ch HDMI?
by Pavel Hofman 31 Jan '24

31 Jan '24

Hi, Users of RPi's hdmi:vc4-hdmi report random channel swapping after an xrun. Tested (among other clients) on speaker-test, details https://forums.raspberrypi.com/viewtopic.php?p=2187582#p2187540 Experienced RPi developer has diagnosed the driver - HDMI device and DMA are correctly reset at xrun recovery (i.e. snd_pcm_stop(XRUN) in the driver -> snd_pcm_prepare in the client). Therefore an option is that alsa supplies misaligned 8ch samples after the xrun recovery. Users checked the older HDMI driver bcm2835_audio (bcm2835-pcm.c) which accepts standard S16/24_LE formats and does not require the iec958 plugin and xruns did not cause any channel swaps. Hence aiming at the iec958 plugin. It seems to keep state (e.g. iec->counter) which perhaps may not be reset at snd_pcm_prepare. Thanks a lot, Pavel.

ASoC: rockchip_i2s_tdm calibration clocking problem
by Pavel Hofman 31 Jan '24

31 Jan '24

Hi, I am hitting a clock issue with rockchip_i2s_tdm.c + simple-audio-card (+ RK3308). At boot the mclk clk_i2s0_8ch_tx is (somehow) initialized to some (unimportant?) value 50176000 Hz. Note that this frequency is not multiple of either 48kHz or 44.1kHz. Method asoc_simple_parse_clk() reads this value and sets it to simple_dai->sysclk. Subsequently at asoc_simple_dai_init this "random" initial value is stored to i2s_tdm->mclk_tx_freq: 17.839330] rockchip_i2s_tdm_set_sysclk+0x50/0xbc [snd_soc_rockchip_i2s_tdm] [ 17.839367] snd_soc_dai_set_sysclk+0x38/0xb8 [snd_soc_core] [ 17.839596] asoc_simple_init_dai+0x94/0xc0 [snd_soc_simple_card_utils] [ 17.839640] asoc_simple_dai_init+0x130/0x230 [snd_soc_simple_card_utils] [ 17.839672] snd_soc_link_init+0x28/0x90 [snd_soc_core] [ 17.839843] snd_soc_bind_card+0x60c/0xbb4 [snd_soc_core] When starting playback, called by rockchip_i2s_tdm_hw_params(), rockchip_i2s_tdm_calibrate_mclk() correctly switches parent of mclk_parent to correct root pll clock mclk_root0/1 for the given samplerate and correctly configures mclk_parent frequency. https://github.com/torvalds/linux/blob/master/sound/soc/rockchip/rockchip_i… But right after that, the next line of rockchip_i2s_tdm_hw_params() calls rockchip_i2s_tdm_set_mclk() https://github.com/torvalds/linux/blob/master/sound/soc/rockchip/rockchip_i… This method calls clk_set_rate(i2s_tdm->mclk_tx, i2s_tdm->mclk_tx_freq), which resets the clock and its parental chain to the original incorrect value stored in i2s_tdm->mclk_tx_freq from the dai initialization. https://github.com/torvalds/linux/blob/master/sound/soc/rockchip/rockchip_i… As a result, no matter what sample rate is being played, the i2s mclk clock always ends up configured incorrectly. DTS I2S sets all clocks, therefore the clk calibration in rockchip_i2s_tdm.c should be (and is) used: i2s_8ch_0: i2s@ff300000 { compatible = "rockchip,rk3308-i2s-tdm"; reg = <0x0 0xff300000 0x0 0x1000>; interrupts = <GIC_SPI 48 IRQ_TYPE_LEVEL_HIGH>; clocks = <&cru SCLK_I2S0_8CH_TX>, <&cru SCLK_I2S0_8CH_RX>, <&cru HCLK_I2S0_8CH>, <&cru SCLK_I2S0_8CH_TX_SRC>, <&cru SCLK_I2S0_8CH_RX_SRC>, <&cru PLL_VPLL0>, <&cru PLL_VPLL1>; clock-names = "mclk_tx", "mclk_rx", "hclk", "mclk_tx_src", "mclk_rx_src", "mclk_root0", "mclk_root1"; ......... It seems to me that the calibration code should also rewrite the initially incorrect i2s_tdm->mclk_tx_freq and i2s_tdm->mclk_rx_freq with correct values corresponding to the momentary hw_params rate, or maybe rockchip_i2s_tdm_set_mclk() should not be called if rockchip_i2s_tdm_calibrate_mclk() is called a line above (i.e. putting the call to rockchip_i2s_tdm_set_mclk() into "else" branch). Thank you very much for help. With regards, Pavel.

[PATCH 1/2] dt-bindings: pinctrl: Unify "input-debounce" schema
by Rob Herring 31 Jan '24

nuvoton,npcm845-pinctrl defines the common "input-debounce" property as an array rather than an scalar.
