[PATCH v6 00/13] Add support for IIO devices in ASoC
by Herve Codina 12 Jul '23

12 Jul '23

Several weeks ago, I sent a series [1] for adding a potentiometer as an auxiliary device in ASoC. The feedback was that the potentiometer should be directly handled in IIO (as other potentiometers) and something more generic should be present in ASoC in order to have a binding to import some IIO devices into sound cards. The series related to the IIO potentiometer device is already applied. This series introduces audio-iio-aux. Its goal is to offer the binding between IIO and ASoC. It exposes attached IIO devices as ASoC auxiliary devices and allows to control them through mixer controls. On my system, the IIO device is a potentiometer and it is present in an amplifier design present in the audio path.

[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 v2] soundwire: amd: Fix a check for errors in probe()
by Dan Carpenter 10 Jul '23

This code has two problems: 1) The devm_ioremap() function returns NULL, not error pointers. 2) It's checking the wrong variable. ->mmio instead of ->acp_mmio.

[PATCH v2 0/4] soundwire: qcom: stablity fixes
by Srinivas Kandagatla 10 Jul '23

10 Jul '23

During x13s audio testing we hit few corner cases due to issues in codec drivers and some obvious code bugs. Here are the fixes for those issues, mostly the issues are around devices loosing the sync in between runtime pm suspend resume path. With codec fixes along with these fixes, audio on x13s is pretty stable. Thanks, Srini Changes since v1: - dropped runtime pm changes patch as unable to reproduced it anymore - fixed clk stop flag as suggested by Pierre - rebased on top of linux-next Srinivas Kandagatla (4): soundwire: qcom: update status correctly with mask soundwire: qcom: wait for fifo to be empty before suspend soundwire: qcom: add software workaround for bus clash interrupt assertion soundwire: qcom: set clk stop need reset flag at runtime drivers/soundwire/qcom.c | 100 ++++++++++++++++++++++++++------------- 1 file changed, 68 insertions(+), 32 deletions(-) -- 2.21.0

[PATCH] ASoC: fsl_sai: Enable MCTL_MCLK_EN bit for master mode
by Shengjiu Wang 07 Jul '23

On i.MX8MM, the MCTL_MCLK_EN bit it is not only the gate for MCLK output to PAD, but also the gate bit between root clock and SAI module, So it is need to be enabled for master mode, otherwise there is no bclk generated.

[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
