[PATCHv4 7/9] ASoC: fsl-asoc-card: add DT clock "cpu_sysclk" with generic codec
by Elinor Montmasson 31 May '24

31 May '24

Add an optional DT clock "cpu_sysclk" to get the CPU DAI system-clock frequency when using the generic codec. It is set for both Tx and Rx. The way the frequency value is used is up to the CPU DAI driver implementation.

[PATCHv4 8/9] ASoC: fsl-asoc-card: add DT property "cpu-system-clock-direction-out"

Add new optional DT property "cpu-system-clock-direction-out" to set sysclk direction as "out" for the CPU DAI when using the generic codec. It is set for both Tx and Rx. If not set, the direction is "in". The way the direction value is used is up to the CPU DAI driver implementation.

[PATCH] ALSA: hda: cs35l41: Possible null pointer dereference in cs35l41_hda_unbind()
by Simon Trimmer 31 May '24

31 May '24

The cs35l41_hda_unbind() function clears the hda_component entry matching it's index and then dereferences the codec pointer held in the first element of the hda_component array, this is an issue when the device index was 0. Instead use the codec pointer stashed in the cs35l41_hda structure as it will still be valid.

[PATCH v6 0/1] Add tas2781 driver for SPI.
by Baojun Xu 31 May '24

31 May '24

This patch was used to add TAS2781 devices on SPI support in sound/pci/hda. It use ACPI node descript about parameters of TAS2781 on SPI, it like: Scope (_SB.PC00.SPI0) { Device (GSPK) { Name (_HID, "TXNW2781") // _HID: Hardware ID Method (_CRS, 0, NotSerialized) { Name (RBUF, ResourceTemplate () { SpiSerialBusV2 (...) SpiSerialBusV2 (...) } } } } And in platform/x86/serial-multi-instantiate.c, those spi devices will be added into system as a single SPI device, so TAS2781 SPI driver will probe twice for every single SPI device. And driver will also parser mono DSP firmware binary and RCA binary for itself.

Why do you have to rush in and take over others' patches? Isn't that selfish of you? Your behavior disrespects others' efforts and enthusiasm, and it undermines the collaborative, harmonious, and fair atmosphere of the community.

[PATCH v2 0/2] Support Tegra I2S client format conversion
by Sameer Pujar 30 May '24

30 May '24

From: Mohan Kumar <mkumard(a)nvidia.com> The AHUB HW modules are interconnected with CIF which are capable of supporting Channel and Sample bit format conversion. Due to this, the I2S Client can have different Channel and Sample bit from the hw_params() and this config is passed from CIF port of I2S DT node which can help to perform this conversion. - First change to split simple_fixup_sample_fmt to support returning sample format value - Second patch to support Tegra I2S client channel and sample format programming based on CIF port from DT node. Changelog ========= v2: - Fix sparse warning related to incorrect type assignment for variable 'sample_format' in hw_params() call. The defect was reported by "kernel test robot <lkp(a)intel.com>" and details can be found below: https://lore.kernel.org/oe-kbuild-all/202405211805.UMAdiH0d-lkp@intel.com/ Mohan Kumar (2): ASoC: simple-card-utils: Split simple_fixup_sample_fmt func ASoC: tegra: I2S client convert formats handling include/sound/simple_card_utils.h | 2 + sound/soc/generic/simple-card-utils.c | 26 +++++++--- sound/soc/tegra/tegra210_i2s.c | 71 +++++++++++++++++++++++++-- sound/soc/tegra/tegra210_i2s.h | 2 + 4 files changed, 91 insertions(+), 10 deletions(-) -- 2.45.1
