ASoC: rockchip_i2s_tdm calibration clocking problem
by Pavel Hofman 04 Mar '24

04 Mar '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] ALSA: dice: add stream format parameters for Weiss devices
by Michele Perrone 29 Feb '24

29 Feb '24

Hard-coded stream format parameters are added for Weiss Engineering FireWire devices. When the device vendor and model match, the parameters are copied into the stream format cache. This allows for setting all supported sampling rates up to 192kHz, and consequently adjusting the number of available I/O channels.

[PATCH 00/13] irqchip: Convert to platform remove callback returning void
by Uwe Kleine-König 27 Feb '24

27 Feb '24

this series converts all drivers below drivers/irqchip to use .remove_new(). See commit 5c5a7680e67b ("platform: Provide a remove callback that returns no value") for an extended explanation and the eventual goal. The TL;DR; is to make it harder for driver authors to leak resources. The drivers touched here are all fine though and don't return early in .remove(). So all conversions in this series are trivial.

[PATCH v12 00/15] Add audio support in v4l2 framework
by Shengjiu Wang 23 Feb '24

23 Feb '24

Audio signal processing also has the requirement for memory to memory similar as Video. This asrc memory to memory (memory ->asrc->memory) case is a non real time use case. User fills the input buffer to the asrc module, after conversion, then asrc sends back the output buffer to user. So it is not a traditional ALSA playback and capture case. It is a specific use case, there is no reference in current kernel. v4l2 memory to memory is the closed implementation, v4l2 current support video, image, radio, tuner, touch devices, so it is not complicated to add support for this specific audio case. Because we had implemented the "memory -> asrc ->i2s device-> codec" use case in ALSA. Now the "memory->asrc->memory" needs to reuse the code in asrc driver, so the first 3 patches is for refining the code to make it can be shared by the "memory->asrc->memory" driver. The main change is in the v4l2 side, A /dev/vl4-audioX will be created, user applications only use the ioctl of v4l2 framework. Other change is to add memory to memory support for two kinds of i.MX ASRC module. changes in v12 - minor changes according to comments - drop min_buffers_needed = 1 and V4L2_CTRL_FLAG_UPDATE flag - drop bus_info changes in v11 - add add-fixed-point-test-controls in vivid. - add v4l2_ctrl_fp_compose() helper function for min and max changes in v10 - remove FIXED_POINT type - change code base on media: v4l2-ctrls: add support for fraction_bits - fix issue reported by kernel test robot - remove module_alias changes in v9: - add MEDIA_ENT_F_PROC_AUDIO_RESAMPLER. - add MEDIA_INTF_T_V4L_AUDIO - add media controller support - refine the vim2m-audio to support 8k<->16k conversion. changes in v8: - refine V4L2_CAP_AUDIO_M2M to be 0x00000008 - update doc for FIXED_POINT - address comments for imx-asrc changes in v7: - add acked-by from Mark - separate commit for fixed point, m2m audio class, audio rate controls - use INTEGER_MENU for rate, FIXED_POINT for rate offset - remove used fmts - address other comments for Hans changes in v6: - use m2m_prepare/m2m_unprepare/m2m_start/m2m_stop to replace m2m_start_part_one/m2m_stop_part_one, m2m_start_part_two/m2m_stop_part_two. - change V4L2_CTRL_TYPE_ASRC_RATE to V4L2_CTRL_TYPE_FIXED_POINT - fix warning by kernel test rebot - remove some unused format V4L2_AUDIO_FMT_XX - Get SNDRV_PCM_FORMAT from V4L2_AUDIO_FMT in driver. - rename audm2m to viaudm2m. changes in v5: - remove V4L2_AUDIO_FMT_LPCM - define audio pixel format like V4L2_AUDIO_FMT_S8... - remove rate and format in struct v4l2_audio_format. - Add V4L2_CID_ASRC_SOURCE_RATE and V4L2_CID_ASRC_DEST_RATE controls -

[PATCH v6 0/6] reset: gpio: ASoC: shared GPIO resets
by Krzysztof Kozlowski 22 Feb '24

22 Feb '24

Hi, Dependencies / Merging ====================== 1. Depends on !GPIOLIB stub: https://lore.kernel.org/all/20240125081601.118051-3-krzysztof.kozlowski@lin… 2. Patch #2 (cpufreq: do not open-code of_phandle_args_equal()) and patch #4 (reset: Instantiate reset GPIO controller for shared reset-gpios) depend on OF change (patch #1). Changes in v6 ============= 1. reset/core.c: Add check for number of GPIO cells==2 (Neil). 2. Add Rb/Ack tags. Changes in v5 ============= 1. Minor comments from Philipp: missing cleanup.h, correct indentation of pr_err(), shorten gpio_device_find_by_fwnode() line. 2. Acks/Rbs. Changes in v4 ============= 1. New patches: of: add of_phandle_args_equal() helper cpufreq: do not open-code of_phandle_args_equal() 2. reset-gpio.c: - Drop unneeded comment (Bartosz), add Rb tag. - Do not assign of_node. 3. reset/core.c: - Implement most of Bartosz feedback (I responded to one which I did not implement) and comments from Philipp. - Expect either rcdev->of_args or rcdev->of_node. - Drop __reset_gpios_args_match() and use common helper (Philipp). - Move declarations of automatic-cleanup variables in __reset_add_reset_gpio_lookup() to place of use (Bartosz). - Separate gpio_device_get_label() and kstrdup() (Philipp). - Correct doc for __reset_add_reset_gpio_device(), rewrite few comments. - Drop unneeded "r" variable in __reset_find_rcdev() (Philipp). - Drop of_phandle_args initialization in __of_reset_control_get (Philipp). - Check if CONFIG_RESET_GPIO is enabled before trying to look up reset-gpios. 4. Drop Chris' patch: "i2c: muxes: pca954x: Allow sharing reset GPIO", because discussion is on going. Changes in v3 ============= 1. reset-gpio.c: - Add reset_gpio_of_xlate (Philipp). - reset_gpio_of_args_put->reset_gpio_of_node_put (Philipp). - Expect via platdata of_phandle_args. - Do not call device_set_node() to attach itself to reset consumer (the final device). This was questionable idea in the first place. Bartosz suggested to use GPIO_LOOKUP to solve this. 2. reset/core.c, implement Philipp's feedback. That was a lot: - Commit msg fixes. - Add new platform_device earlier, when reset core found "reset-gpios" but not "resets". - Do not overwrite of_phandle_args. - Expect matching .of_reset_n_cells. - Pass of_phandle_args as platdata to reset-gpio. - Rename reset_gpio_device->reset_gpio_lookup and others. Fix few comments and code cleanup pointed on review. - From Bartosz: Use GPIO_LOOKUP and a lot of cleanup.h in __reset_add_reset_gpio_lookup(). 3. Include here Chris' patch: "i2c: muxes: pca954x: Allow sharing reset GPIO". Changes in v2 ============= 1. wsa884x.c: add missing return in wsa884x_get_reset(), correct comment. 2. qcom,wsa8840.yaml: fix oneOf syntax. 3. reset-gpio.c: - Fix smatch warning on platdata evaluation. - Parse GPIO args and store them in rc.of_args. 4. reset/core.c: - Revise approach based on Bartosz comments: parse the reset-gpios phandle with arguments, do not use deprecated API and do not rely on gpio_desc pointer. - Create a list of instantiated platform devices to avoid any duplicates. - After creating reset-gpio platform device, try to get new reset controller or return EPROBE_DEFER. - Drop the "cookie" member and add new "of_args" to "struct reset_controller_dev". Description =========== We have at least few cases where hardware engineers decided to use one powerdown/shutdown/reset GPIO line for multiple devices: 1.

[PATCH] slimbus: core: Remove usage of the deprecated ida_simple_xx() API
by Christophe JAILLET 21 Feb '24

21 Feb '24

ida_alloc() and ida_free() should be preferred to the deprecated ida_simple_get() and ida_simple_remove(). Note that the upper limit of ida_simple_get() is exclusive, but the one of ida_alloc_range() is inclusive. So change this change allows one more device. Previously address 0xFE was never used. Fixes: 46a2bb5a7f7e ("slimbus: core: Add slim controllers support") Signed-off-by: Christophe JAILLET <christophe.jaillet(a)wanadoo.fr> --- /!\ Untested /!\ The change of behavior is motivated by the comment in drivers/slimbus/slimbus.h stating that /* Manager's logical address is set to 0xFF per spec */, so all other values, including 0xFE should be valid, IMHO. So considering this as a bug-fix, I added a Fixes tag. --- drivers/slimbus/core.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/slimbus/core.c b/drivers/slimbus/core.c index d43873bb5fe6..01cbd4621981 100644 --- a/drivers/slimbus/core.c +++ b/drivers/slimbus/core.c @@ -436,8 +436,8 @@ static int slim_device_alloc_laddr(struct slim_device *sbdev, if (ret < 0) goto err; } else if (report_present) { - ret = ida_simple_get(&ctrl->laddr_ida, - 0, SLIM_LA_MANAGER - 1, GFP_KERNEL); + ret = ida_alloc_max(&ctrl->laddr_ida, + SLIM_LA_MANAGER - 1, GFP_KERNEL); if (ret < 0) goto err; -- 2.34.1

[v2 PATCH 0/1] ALSA: virtio: add support for audio controls
by Aiswarya Cyriac 20 Feb '24

20 Feb '24

From: Anton Yakovlev <anton.yakovlev(a)opensynergy.com> Changes in v2 - Fix reporting of incorrect number of items for ENUMERATED controls Implementation of support for audio controls in accordance with the extension of the virtio sound device specification[1] planned for virtio-v1.3-cs01. Design　of virtual audio controls is based on and derived from ALSA audio controls. It allows the driver to perform all standard operations, such as reading and writing audio control value, as well as working with metadata (represented in the TLV form). The driver part was tested on top of the Linux 5.10 kernel. As a device part was used OpenSynergy proprietary implementation.
