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+KS_kOinxaRx38=WxA@xxxxxxxxxxxxxx/ 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.
