[PATCH V3 00/13] soundwire/SOF: add SoundWire Interface support for AMD SOF stack
by Vijendar Mukunda 02 Mar '24

02 Mar '24

This patch series is to redesign existing platform device creation logic for SoundWire managers and Implement generic functions for SoundWire manager probe, start and exit sequence which are common for both Legacy (NO DSP enabled) and SOF stack, and add SoundWire Interface support for AMD SOF stack (ACP 6.3 based platform). Below patch series is reviewed in https://github.com/thesofproject/linux/pull/4699 Changes since V1: - add new commit to update license for amd soundwire manager driver files. - wrap the commit message with in 75 characters. - add amd tag in commit title for soundwire patches Changes since V2: - drop "drivers" tag from commit title for SoundWire patches. This patch series has dependencies. "drivers: soundwire: amd: refactor amd soundwire manager device node creation" patch has dependency on below patch. "ASoC/soundwire: implement generic api for scanning amd soundwire controller" Similarly SOF patches has dependency on Soundwire tree patches. This patch series has to be reviewed and merged in one go.

[PATCH v4 00/39] Add support for sam9x7 SoC family
by Varshini Rajendran 01 Mar '24

01 Mar '24

This patch series adds support for the new SoC family - sam9x7. - The device tree, configs and drivers are added - Clock driver for sam9x7 is added - Support for basic peripherals is added - Target board SAM9X75 Curiosity is added Changes in v4: -------------- - Addressed all the review comments in the patches - Picked up all Acked-by and Reviewed-by tags - Dropped applied patches from the series - Added pwm node and related dt binding documentation - Added support for exporting some clocks to DT - Dropped USB related patches and changes. See NOTE. - All the specific changes are captured in the corresponding patches NOTE: Owing to the discussion here https://lore.kernel.org/linux-devicetree/CAL_JsqJ9PrX6fj-EbffeJce09MXs=B7t+… the USB related changes are dropped from this series in order to enable us to work on the mentioned issues before adding new compatibles as said. The issues/warnings will be addressed in subsequent patches. After which the USB related support for sam9x7 SoCs will be added. Hope this works out fine. Changes in v3: -------------- - Fixed the DT documentation errors pointed out in v2. - Dropped Acked-by tag in tcb DT doc patch as it had to be adapted according to sam9x7 correctly. - Picked by the previously missed tags. - Dropped this patch "dt-bindings: usb: generic-ehci: Document clock-names property" as the warning was not found while validating DT-schema for at91-sam9x75_curiosity.dtb. - Dropped redundant words in the commit message. - Fixed the CHECK_DTBS warnings validated against at91-sam9x75_curiosity.dtb. - Renamed dt nodes according to naming convention. - Dropped unwanted status property in dts. - Removed nodes that are not in use from the board dts. - Removed spi DT doc patch from the series as it was already applied and a fix patch was applied subsequently. Added a patch to remove the compatible to adapt sam9x7. - Added sam9x7 compatibles in usb dt documentation. Changes in v2: -------------- - Added sam9x7 specific compatibles in DT with fallbacks - Documented all the newly added DT compatible strings - Added device tree for the target board sam9x75 curiosity and documented the same in the DT bindings documentation - Removed the dt nodes that are not supported at the moment - Removed the configs added by previous version that are not supported at the moment - Fixed all the corrections in the commit message - Changed all the instances of copyright year to 2023 - Added sam9x7 flag in PIT64B configuration - Moved macro definitions to header file - Added another divider in mck characteristics in the pmc driver - Fixed the memory leak in the pmc driver - Dropped patches that are no longer needed - Picked up Acked-by and Reviewed-by tags Varshini Rajendran (39): dt-bindings: net: cdns,macb: add sam9x7 ethernet interface dt-bindings: atmel-sysreg: add sam9x7 dt-bindings: crypto: add sam9x7 in Atmel AES dt-bindings: crypto: add sam9x7 in Atmel SHA dt-bindings: crypto: add sam9x7 in Atmel TDES dt-bindings: i2c: at91: Add sam9x7 compatible string dt-bindings: atmel-ssc: add microchip,sam9x7-ssc dt-bindings: atmel-nand: add microchip,sam9x7-pmecc dt-bindings: pinctrl: at91: add sam9x7 dt-bindings: rng: atmel,at91-trng: add sam9x7 TRNG dt-bindings: rtt: at91rm9260: add sam9x7 compatible dt-bindings: serial: atmel,at91-usart: add compatible for sam9x7.
