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.

[RFC] ASoC: fsl_sai: Do not set MCTL_MCLK_EN based on the number of registers
by Fabio Estevam 06 Jul '23

06 Jul '23

From: Fabio Estevam <festevam(a)denx.de> Since commit ff87d619ac18 ("ASoC: fsl_sai: Enable MCTL_MCLK_EN bit for master mode") Andreas reports that on an i.MX8MP-based system where MCLK needs to be an input, the MCLK pin is actually an output, despite not having the 'fsl,sai-mclk-direction-output' property present in the devicetree. This commit explains the following: "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." Currently, the decision of using MCTL_MCLK_EN as a clock gate is based on the number of SAI registers present on a platform. This is fragile as it causes issues on i.MX8MP, for example. Fix the problem by introducing a new boolean mclk_en_gates_clock member in the fsl_sai_soc_data structure that indicates that the MCTL_MCLK_EN bit also acts as a gate between the root clock and the SAI block. This allows i.MX8MM to turn on FSL_SAI_MCTL_MCLK_EN as intended and other SoCs such as i.MX8MP can still use MCLK as input.

[PATCH] ALSA: jack: Fix mutex call in snd_jack_report()
by Takashi Iwai 06 Jul '23

06 Jul '23

snd_jack_report() is supposed to be callable from an IRQ context, too, and it's indeed used in that way from virtsnd driver. The fix for input_dev race in commit 1b6a6fc5280e ("ALSA: jack: Access input_dev under mutex"), however, introduced a mutex lock in snd_jack_report(), and this resulted in a potential sleep-in-atomic. For addressing that problem, this patch changes the relevant code to use the object get/put and removes the mutex usage. That is, snd_jack_report(), it takes input_get_device() and leaves with input_put_device() for assuring the input_dev being assigned. Although the whole mutex could be reduced, we keep it because it can be still a protection for potential races between creation and deletion.

[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
