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 v6: -------------- - Addressed all the review comments in the patches - Picked up all Acked-by and Reviewed-by tags - Reverted the IRQ patch to that of version 3 of the same series - All the specific changes are captured in the corresponding patches Changes in v5: -------------- - Addressed all the review comments in the patches - Picked up all Acked-by and Reviewed-by tags - Dropped applied patches from the series - Addressed the ABI breakage reported in the IRQ patch - All the specific changes are captured in the corresponding patches 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@mail.gmail.com/ 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 Hari Prasath (1): irqchip/atmel-aic5: Add support for sam9x7 aic Varshini Rajendran (26): dt-bindings: atmel-sysreg: add sam9x7 dt-bindings: mfd: syscon: add microchip's sam9x7 sfr dt-bindings: atmel-ssc: add microchip,sam9x7-ssc dt-bindings: serial: atmel,at91-usart: add compatible for sam9x7. dt-bindings: microchip: atmel,at91rm9200-tcb: add sam9x7 compatible ARM: at91: pm: add support for sam9x7 SoC family ARM: at91: pm: add sam9x7 SoC init config ARM: at91: add support in SoC driver for new sam9x7 dt-bindings: clocks: atmel,at91sam9x5-sckc: add sam9x7 dt-bindings: clocks: atmel,at91rm9200-pmc: add sam9x7 clock controller clk: at91: clk-sam9x60-pll: re-factor to support individual core freq outputs clk: at91: sam9x7: add support for HW PLL freq dividers clk: at91: sama7g5: move mux table macros to header file dt-bindings: clock: at91: Allow PLLs to be exported and referenced in DT clk: at91: sam9x7: add sam9x7 pmc driver dt-bindings: interrupt-controller: Add support for sam9x7 aic power: reset: at91-poweroff: lookup for proper pmc dt node for sam9x7 power: reset: at91-reset: add reset support for sam9x7 SoC power: reset: at91-reset: add sdhwc support for sam9x7 SoC dt-bindings: reset: atmel,at91sam9260-reset: add sam9x7 dt-bindings: power: reset: atmel,sama5d2-shdwc: add sam9x7 ARM: at91: Kconfig: add config flag for SAM9X7 SoC ARM: configs: at91: enable config flags for sam9x7 SoC family ARM: dts: at91: sam9x7: add device tree for SoC dt-bindings: arm: add sam9x75 curiosity board ARM: dts: microchip: sam9x75_curiosity: add sam9x75 curiosity board .../devicetree/bindings/arm/atmel-at91.yaml | 6 + .../devicetree/bindings/arm/atmel-sysregs.txt | 6 +- .../bindings/clock/atmel,at91rm9200-pmc.yaml | 2 + .../bindings/clock/atmel,at91sam9x5-sckc.yaml | 4 +- .../interrupt-controller/atmel,aic.yaml | 1 + .../devicetree/bindings/mfd/syscon.yaml | 188 +-- .../devicetree/bindings/misc/atmel-ssc.txt | 1 + .../power/reset/atmel,sama5d2-shdwc.yaml | 3 + .../reset/atmel,at91sam9260-reset.yaml | 4 + .../bindings/serial/atmel,at91-usart.yaml | 9 +- .../soc/microchip/atmel,at91rm9200-tcb.yaml | 20 +- arch/arm/boot/dts/microchip/Makefile | 3 + .../dts/microchip/at91-sam9x75_curiosity.dts | 312 +++++ arch/arm/boot/dts/microchip/sam9x7.dtsi | 1226 +++++++++++++++++ arch/arm/configs/at91_dt_defconfig | 1 + arch/arm/mach-at91/Kconfig | 22 +- arch/arm/mach-at91/Makefile | 1 + arch/arm/mach-at91/generic.h | 2 + arch/arm/mach-at91/pm.c | 29 + arch/arm/mach-at91/sam9x7.c | 33 + drivers/clk/at91/Makefile | 1 + drivers/clk/at91/clk-sam9x60-pll.c | 42 +- drivers/clk/at91/pmc.h | 18 + drivers/clk/at91/sam9x60.c | 7 + drivers/clk/at91/sam9x7.c | 946 +++++++++++++ drivers/clk/at91/sama7g5.c | 42 +- drivers/irqchip/irq-atmel-aic5.c | 10 + drivers/power/reset/Kconfig | 4 +- drivers/power/reset/at91-sama5d2_shdwc.c | 1 + drivers/soc/atmel/soc.c | 23 + drivers/soc/atmel/soc.h | 9 + include/dt-bindings/clock/at91.h | 4 + 32 files changed, 2840 insertions(+), 140 deletions(-) create mode 100644 arch/arm/boot/dts/microchip/at91-sam9x75_curiosity.dts create mode 100644 arch/arm/boot/dts/microchip/sam9x7.dtsi create mode 100644 arch/arm/mach-at91/sam9x7.c create mode 100644 drivers/clk/at91/sam9x7.c
