[PATCH 1/1] ASoC: dwc: Add TDM mode support
by Maxim Kochetkov 12 Jul '23

12 Jul '23

Depending on hardware implementaion of DWC I2S controller may support TDM mode if enabled in SoC at design time. Unfortunately there is no way to detect TDM capability for DWC by reading registers. Anyway, if such capability enabled, TDM mode can be enabled and configured by dai-tdm-slot-* DT options.

[PATCH v3 0/6] Introduce STM32 system bus
by Gatien Chevallier 05 Jul '23

05 Jul '23

Document STM32 System Bus. This bus is intended to control firewall access for the peripherals connected to it. For every peripheral, the bus checks the firewall registers to see if the peripheral is configured as non-secure. If the peripheral is configured as secure, the node is marked populated, so the device won't be probed. This is useful as a firewall configuration sanity check and avoid platform crashes in case peripherals are incorrectly configured. The STM32 System Bus implements the feature-domain-controller bindings. It is used by peripherals to reference a domain controller, in this case the firewall feature domain. The bus uses the ID referenced by the feature-domains property to know where to look in the firewall to get the security configuration for the peripheral. This allows a device tree description rather than a hardcoded peripheral table in the bus driver. On STM32MP13/15 platforms, the firewall bus is represented by the ETZPC node, which is responsible for the securing / MCU isolating the capable peripherals. STM32MP13/15 device trees are updated in this series to implement the bus. All peripherals that are securable or MCU isolation capable by the ETZPC are connected to the bus. Changes in V2: - Corrected YAMLS errors highlighted by Rob's robot - Re-ordered Signed-off-by tags in two patches Changes in V3: - Document feature-domains property in YAML documentation for concerned periperals under the System Bus - Fix STM32 System Bus YAML documentation - Remove STM32 System bus bindings that were currently used as helpers for device tree - Correct few errors in driver - Add missing peripherals under the System Bus that were in SoC variation device tree files - Fix node names Gatien Chevallier (5): dt-bindings: treewide: add feature-domains description in binding files dt-bindings: bus: add STM32 System Bus bus: stm32_sys_bus: add support for STM32MP15 and STM32MP13 system bus ARM: dts: stm32: add ETZPC as a system bus for STM32MP15x boards ARM: dts: stm32: add ETZPC as a system bus for STM32MP13x boards Oleksii Moisieiev (1): dt-bindings: Document common device controller bindings .../devicetree/bindings/bus/st,sys-bus.yaml | 127 + .../bindings/crypto/st,stm32-hash.yaml | 5 + .../devicetree/bindings/dma/st,stm32-dma.yaml | 5 + .../bindings/dma/st,stm32-dmamux.yaml | 5 + .../feature-domain-controller.yaml | 84 + .../devicetree/bindings/i2c/st,stm32-i2c.yaml | 5 + .../bindings/iio/adc/st,stm32-adc.yaml | 5 + .../bindings/iio/adc/st,stm32-dfsdm-adc.yaml | 5 + .../bindings/iio/dac/st,stm32-dac.yaml | 5 + .../bindings/media/st,stm32-cec.yaml | 5 + .../bindings/media/st,stm32-dcmi.yaml | 5 + .../memory-controllers/st,stm32-fmc2-ebi.yaml | 5 + .../bindings/mfd/st,stm32-lptimer.yaml | 5 + .../bindings/mfd/st,stm32-timers.yaml | 6 + .../devicetree/bindings/mmc/arm,pl18x.yaml | 5 + .../devicetree/bindings/net/stm32-dwmac.yaml | 5 + .../bindings/phy/phy-stm32-usbphyc.yaml | 5 + .../bindings/regulator/st,stm32-vrefbuf.yaml | 5 + .../devicetree/bindings/rng/st,stm32-rng.yaml | 5 + .../bindings/serial/st,stm32-uart.yaml | 5 + .../bindings/sound/st,stm32-i2s.yaml | 5 + .../bindings/sound/st,stm32-sai.yaml | 5 + .../bindings/sound/st,stm32-spdifrx.yaml | 5 + .../bindings/spi/st,stm32-qspi.yaml | 5 + .../devicetree/bindings/spi/st,stm32-spi.yaml | 5 + .../devicetree/bindings/usb/dwc2.yaml | 5 + MAINTAINERS | 6 + arch/arm/boot/dts/stm32mp131.dtsi | 407 +-- arch/arm/boot/dts/stm32mp133.dtsi | 51 +- arch/arm/boot/dts/stm32mp13xc.dtsi | 19 +- arch/arm/boot/dts/stm32mp13xf.dtsi | 18 +- arch/arm/boot/dts/stm32mp151.dtsi | 2722 +++++++++-------- arch/arm/boot/dts/stm32mp153.dtsi | 52 +- arch/arm/boot/dts/stm32mp15xc.dtsi | 19 +- drivers/bus/Kconfig | 9 + drivers/bus/Makefile | 1 + drivers/bus/stm32_sys_bus.c | 168 + 37 files changed, 2208 insertions(+), 1596 deletions(-) create mode 100644 Documentation/devicetree/bindings/bus/st,sys-bus.yaml create mode 100644 Documentation/devicetree/bindings/feature-controllers/feature-domain-controller.yaml create mode 100644 drivers/bus/stm32_sys_bus.c -- 2.35.3

[PATCH] ASoC: mediatek: mt8188: add constraints for PCM
by Trevor Wu 04 Jul '23

04 Jul '23

For certain projects, only a limited number of parameters are necessary. Therefore, it may be beneficial to add constraints that restrict the capacity of the PCM.

[PATCH 0/5] ASoC: codecs: wcd938x/wcd934x: loglevel fix and cleanups
by Johan Hovold 03 Jul '23

03 Jul '23

When investigating a race in the wcd938x driver I noticed that the MBHC impedance measurements where printed at error loglevel which is clearly wrong. Fix that, and clean up the logging somewhat by using dev_printk() and addressing some style issues. Included are also two patches that drop the bogus inline keywords from the functions involved.
