This series adds basic support for the Nuvoton WPCM450 BMC SoC. It's an older SoC but still commonly found on eBay, mostly in Supermicro X9 server boards. Third-party documentation is available at: https://github.com/neuschaefer/wpcm450/wiki Patches 1-4 add devicetree bindings for the WPCM450 SoC and its various parts. Patches 5-7 add arch and driver support. Patches 8 and 9 add a devicetree for the SoC and a board based on it. Patch 10 finally updates the MAINTAINERS file. Patch 2 requires "dt-bindings: arm: Convert nuvoton,npcm750 binding to YAML" (https://lore.kernel.org/lkml/20210320164023.614059-1-j.neuschaefer@xxxxxxx/) v2: - Various improvements to the AIC irqchip driver, thanks to Marc Zyngier's review - I dropped the timer patches, which have been applied by Daniel Lezcano - I dropped the serial patches, which have been applied to tty-next by Greg KH v1: - https://lore.kernel.org/lkml/20210320181610.680870-1-j.neuschaefer@xxxxxxx/ Jonathan Neuschäfer (10): dt-bindings: vendor-prefixes: Add Supermicro dt-bindings: arm: npcm: Add nuvoton,wpcm450 compatible string dt-bindings: interrupt-controller: Add nuvoton,wpcm450-aic dt-bindings: watchdog: npcm: Add nuvoton,wpcm450-wdt ARM: npcm: Introduce Nuvoton WPCM450 SoC irqchip: Add driver for WPCM450 interrupt controller watchdog: npcm: Add support for WPCM450 ARM: dts: Add devicetree for Nuvoton WPCM450 BMC chip ARM: dts: Add devicetree for Supermicro X9SCi-LN4F based on WPCM450 MAINTAINERS: Add entry for Nuvoton WPCM450 .../devicetree/bindings/arm/npcm/npcm.yaml | 6 + .../nuvoton,wpcm450-aic.yaml | 39 +++++ .../devicetree/bindings/vendor-prefixes.yaml | 2 + .../bindings/watchdog/nuvoton,npcm-wdt.txt | 3 +- MAINTAINERS | 9 + arch/arm/boot/dts/Makefile | 2 + .../nuvoton-wpcm450-supermicro-x9sci-ln4f.dts | 40 +++++ arch/arm/boot/dts/nuvoton-wpcm450.dtsi | 76 +++++++++ arch/arm/mach-npcm/Kconfig | 13 +- arch/arm/mach-npcm/Makefile | 1 + arch/arm/mach-npcm/wpcm450.c | 13 ++ drivers/irqchip/Kconfig | 6 + drivers/irqchip/Makefile | 1 + drivers/irqchip/irq-wpcm450-aic.c | 161 ++++++++++++++++++ drivers/watchdog/npcm_wdt.c | 1 + 15 files changed, 371 insertions(+), 2 deletions(-) create mode 100644 Documentation/devicetree/bindings/interrupt-controller/nuvoton,wpcm450-aic.yaml create mode 100644 arch/arm/boot/dts/nuvoton-wpcm450-supermicro-x9sci-ln4f.dts create mode 100644 arch/arm/boot/dts/nuvoton-wpcm450.dtsi create mode 100644 arch/arm/mach-npcm/wpcm450.c create mode 100644 drivers/irqchip/irq-wpcm450-aic.c -- 2.30.2
