[PATCH] slimbus: core: make slimbus_bus const
by Ricardo B. Marliere 21 Feb '24

21 Feb '24

Since commit d492cc2573a0 ("driver core: device.h: make struct bus_type a const *"), the driver core can properly handle constant struct bus_type, move the slimbus_bus variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.

[PATCH] ASoC: cs35l56: Must clear HALO_STATE before issuing SYSTEM_RESET
by Richard Fitzgerald 21 Feb '24

21 Feb '24

The driver must write 0 to HALO_STATE before sending the SYSTEM_RESET command to the firmware. HALO_STATE is in DSP memory, which is preserved across a soft reset. The SYSTEM_RESET command does not change the value of HALO_STATE. There is period of time while the CS35L56 is resetting, before the firmware has started to boot, where a read of HALO_STATE will return the value it had before the SYSTEM_RESET. If the driver does not clear HALO_STATE, this would return BOOT_DONE status even though the firmware has not booted.

[PATCH v8] ASoc: tas2783: Add tas2783 codec driver
by Shenghao Ding 20 Feb '24

20 Feb '24

The tas2783 is a smart audio amplifier with integrated MIPI SoundWire interface (Version 1.2.1 compliant), I2C, and I2S/TDM interfaces designed for portable applications. An on-chip DSP supports Texas Instruments SmartAmp speaker protection algorithm. The integrated speaker voltage and current sense provides for real-time monitoring of lodspeakers. The ASoC component provides the majority of the functionality of the device, all the audio functions. Signed-off-by: Shenghao Ding <shenghao-ding(a)ti.com> --- Change in v8: - simplify tasdevice_set_sdw_stream - fixed some Linux coding style - fixed the spelling mistakes - Select left/right channel based on unique id - a longer description has been added - remove unused crc8 in KCONFIG - Invert of RE here means reciprocal of RE - correct indentation - correct the wrong pow calibrated register - correct comment on RESET register - fixed usually lines don't end with an open parenthesis - fixed tasdevice_sdw_shutdown - use defines for function, entity, etc. for readable - remove unnecessary codec_lock in component_probe() - remove struct sdw_stream_data - remove unused macro definitions - use BIT(2) and BIT(1) instead of 0x2 and 0x1 - implement pm_runtime - reg_start is u8, reg_start + i only adds i byte, it should be reg_start + i * 4, because the calibration values - fixed total_sz in tas2783_calibration - add a define for TASDEVICE_REG(0, 0, 0x0a) - rework macro style in header file - Add select CRC32 - rewrite the mute and the return value handling - Add comments on bin file - Add link_id into the fw name to distinguish the same sdw id on different sdw id. - remove unnecessary mutex_lock - use set_active() in tasdevice_io_init and move all other parts in the probe. - move pm_runtime_get_noresume to the probe - fix the return value of putvol function - add put_noidle in tasdevice_sdw_remove - remove unused header file(of.h) - correct the style of the multi-line comment - Set the readable registers in tas2783_readable_register for debugfs - Use new PM macros - Use default put and get inline SOC_SINGLE_RANGE_TLV and SOC_SINGLE_SX_TLV - Use respective %pt to log the calibrated time - Remove unnecessary struct tm - Add trailing comma tasdevice_dapm_widgets and tasdevice_audio_map - Rewrite the return value handling in tasdevice_sdw_probe - use dev_num instead of id.unique_id - rework the log --- sound/soc/codecs/Kconfig | 16 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/tas2783-sdw.c | 844 +++++++++++++++++++++++++++++++++ sound/soc/codecs/tas2783.h | 103 ++++ 4 files changed, 965 insertions(+) create mode 100644 sound/soc/codecs/tas2783-sdw.c create mode 100644 sound/soc/codecs/tas2783.h diff --git a/sound/soc/codecs/Kconfig b/sound/soc/codecs/Kconfig index 59f9742e9ff4..6ba3fd0c0811 100644 --- a/sound/soc/codecs/Kconfig +++ b/sound/soc/codecs/Kconfig @@ -247,6 +247,7 @@ config SND_SOC_ALL_CODECS imply SND_SOC_TAS2781_COMLIB imply SND_SOC_TAS2781_FMWLIB imply SND_SOC_TAS2781_I2C + imply SND_SOC_TAS2783 imply SND_SOC_TAS5086 imply SND_SOC_TAS571X imply SND_SOC_TAS5720 @@ -1847,6 +1848,21 @@ config SND_SOC_TAS2781_I2C algo coefficient setting, for one, two or even multiple TAS2781 chips. +config SND_SOC_TAS2783 + tristate "Texas Instruments TAS2783 speaker amplifier (sdw)" + depends on SOUNDWIRE + depends on EFI + select REGMAP + select REGMAP_SOUNDWIRE + select CRC32 + select CRC32_SARWATE + help + Enable support for Texas Instruments TAS2783 Smart Amplifier + Digital input mono Class-D and DSP-inside audio power amplifiers. + TAS2783 supports the MIPI SoundWire v1.2 compatible interface + for audio and control data.

[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.

[PATCH] ALSA: firewire-lib: fix to check cycle continuity
by Takashi Sakamoto 19 Feb '24

19 Feb '24

The local helper function to compare the given pair of cycle count evaluates them. If the left value is less than the right value, the function returns negative value. If the safe cycle is less than the current cycle, it is the case of cycle lost. However, it is not currently handled properly. This commit fixes the bug.

[PATCH 0/4] ALSA: oxfw: add support for Miglia Harmony Audio
by Takashi Sakamoto 19 Feb '24

19 Feb '24

Hi, There used to be a company called Miglia Technologies Ltd. in the UK, and the company was selling a product called Harmony Audio in 2004. Upon obtaining the product by chance recently and examining its internals, it was revealed that it utilizes Oxford Semiconductor OXFW970 for its communication function in IEEE 1394 bus. This patchset adds support for the model. Takashi Sakamoto (4): ALSA: oxfw: use const qualifier for immutable argument ALSA: oxfw: support the case that AV/C Stream Format Information command is not available ALSA: firewire-lib: handle quirk to calculate payload quadlets as data block counter ALSA: oxfw: add support for Miglia Harmony Audio sound/firewire/amdtp-stream.c | 12 ++-- sound/firewire/amdtp-stream.h | 4 ++ sound/firewire/oxfw/oxfw-stream.c | 100 +++++++++++++++++++++++------- sound/firewire/oxfw/oxfw.c | 10 ++- sound/firewire/oxfw/oxfw.h | 7 ++- 5 files changed, 103 insertions(+), 30 deletions(-) -- 2.40.1

[PATCH] clk: constify the of_phandle_args argument of of_clk_provider
by Krzysztof Kozlowski 19 Feb '24

19 Feb '24

None of the implementations of the get() and get_hw() callbacks of "struct of_clk_provider" modify the contents of received of_phandle_args pointer. They treat it as read-only variable used to find the clock to return. Make obvious that implementations are not supposed to modify the of_phandle_args, by making it a pointer to const.
