Some maintainers don't like cherry picking. In any case, this is at least v2. Best regards, Krzysztof

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings are fixed by another series. Ultimately, it is up to the platform maintainer whether these warnings are acceptable or not. No need to reply unless the platform maintainer has comments. If you already ran DT checks and didn't see these error(s), then make sure dt-schema is up to date: pip3 install dtschema --upgrade New warnings running 'make CHECK_DTBS=y microchip/at91-sama7d65_curiosity.dtb' for cover.1732030972.git.Ryan.Wanner@microchip.com: arch/arm/boot/dts/microchip/at91-sama7d65_curiosity.dtb: /soc/pinctrl@e0014000: failed to match any schema with compatible: ['microchip,sama7d65-pinctrl'] arch/arm/boot/dts/microchip/at91-sama7d65_curiosity.dtb: /soc/timer@e1800000: failed to match any schema with compatible: ['microchip,sama7d65-pit64b', 'microchip,sam9x60-pit64b'] arch/arm/boot/dts/microchip/at91-sama7d65_curiosity.dtb: /soc/timer@e1800000: failed to match any schema with compatible: ['microchip,sama7d65-pit64b', 'microchip,sam9x60-pit64b'] arch/arm/boot/dts/microchip/at91-sama7d65_curiosity.dtb: /soc/timer@e1804000: failed to match any schema with compatible: ['microchip,sama7d65-pit64b', 'microchip,sam9x60-pit64b'] arch/arm/boot/dts/microchip/at91-sama7d65_curiosity.dtb: /soc/timer@e1804000: failed to match any schema with compatible: ['microchip,sama7d65-pit64b', 'microchip,sam9x60-pit64b']
From: Ryan Wanner <Ryan.Wanner@microchip.com> This series adds support for the SAMA7D65 SoC. There have been patches in this series that have been tagged as Reviewed-by or Acked-by, I will link these threads below. 1) https://lore.kernel.org/lkml/20240829-sama7d65-core-dt-v1-1-e5d882886f59@microchip.com/ 2) https://lore.kernel.org/lkml/20240829-sama7d65-sck-v1-1-3e7b19e3cbf9@microchip.com/ 3) https://lore.kernel.org/lkml/20240829-sama7d65-next-v1-1-53d4e50b550d@microchip.com/ 4) https://lore.kernel.org/lkml/1da0abbb-94e5-42fd-a2d2-71d5d7d253fb@microchip.com/ The clock system patches have been sent before and are added to this set to follow the correct practice of submitting patches. I will list that thread below. 1) https://lore.kernel.org/linux-arm-kernel/d970e158-db74-4ffe-9fb4-57026ac0a947@tuxon.dev/ Dharma Balasubiramani (7): dt-bindings: mfd: atmel,sama5d2-flexcom: add microchip,sama7d65-flexcom dt-bindings: atmel-sysreg: add sama7d65 RAM and PIT dt-bindings: mmc: atmel,sama5d2-sdhci: add microchip,sama7d65-sdhci dt-bindings: serial: atmel,at91-usart: add microchip,sama7d65-usart dt-bindings: pinctrl: at91-pio4: add microchip,sama7d65-pinctrl dt-bindings: clocks: atmel,at91sam9x5-sckc: add sama7d65 dt-bindings: clock: Add SAMA7D65 PMC compatible string Romain Sioen (2): dt-bindings: ARM: at91: Document Microchip SAMA7D65 Curiosity ARM: dts: microchip: add support for sama7d65_curiosity board Ryan Wanner (5): ARM: configs: at91: sama7: add new SoC config ARM: dts: microchip: add sama7d65 SoC DT clk: at91: clk-master: increase maximum number of clocks clk: at91: clk-sam9x60-pll: increase maximum amount of plls clk: at91: sama7d65: add sama7d65 pmc driver Varshini Rajendran (1): dt-bindings: clock: at91: Allow MCKs to be exported and referenced in DT .../devicetree/bindings/arm/atmel-at91.yaml | 7 + .../devicetree/bindings/arm/atmel-sysregs.txt | 14 +- .../bindings/clock/atmel,at91rm9200-pmc.yaml | 2 + .../bindings/clock/atmel,at91sam9x5-sckc.yaml | 1 + .../bindings/mfd/atmel,sama5d2-flexcom.yaml | 9 +- .../bindings/mmc/atmel,sama5d2-sdhci.yaml | 1 + .../pinctrl/atmel,at91-pio4-pinctrl.txt | 1 + .../bindings/serial/atmel,at91-usart.yaml | 1 + arch/arm/boot/dts/microchip/Makefile | 3 + .../dts/microchip/at91-sama7d65_curiosity.dts | 89 ++ .../arm/boot/dts/microchip/sama7d65-pinfunc.h | 947 ++++++++++++ arch/arm/boot/dts/microchip/sama7d65.dtsi | 155 ++ arch/arm/configs/multi_v7_defconfig | 1 + arch/arm/configs/sama7_defconfig | 1 + arch/arm/mach-at91/Kconfig | 12 + drivers/clk/at91/Makefile | 1 + drivers/clk/at91/clk-master.c | 2 +- drivers/clk/at91/clk-sam9x60-pll.c | 2 +- drivers/clk/at91/pmc.c | 1 + drivers/clk/at91/sama7d65.c | 1373 +++++++++++++++++ include/dt-bindings/clock/at91.h | 4 + 21 files changed, 2614 insertions(+), 13 deletions(-) create mode 100644 arch/arm/boot/dts/microchip/at91-sama7d65_curiosity.dts create mode 100644 arch/arm/boot/dts/microchip/sama7d65-pinfunc.h create mode 100644 arch/arm/boot/dts/microchip/sama7d65.dtsi create mode 100644 drivers/clk/at91/sama7d65.c
