Hello, This series adds initial support for Actions Semiconductor S500 (ARMv7) and S900 (ARMv8) SoCs. v3 has the serial driver working almost equally for both, still glitch on S900. SMP support and power-gating for S500 are implemented, so both get 4 CPUs up. https://github.com/afaerber/linux/commits/bg96-next Booting from U-Boot is straightforward on both boards: https://en.opensuse.org/HCL:Guitar https://en.opensuse.org/HCL:Bubblegum-96 Have a lot of fun! Cheers, Andreas v2 -> v3: * Clocksource fix * Clocksource cleanups (Daniel) * Serial cleanups * Add S500 CPU enable-method * Add power domain driver * Rework clocksource for S900 compatibility v1 -> v2: * S900 DT fixes (Mark) * Kconfig name changes (Arnd) * Bubblegum-96 .dts rename * Vendor prefix rename * Minor cleanups * Add serial driver * Add MAINTAINERS section * Use SPDX-License-Identifier in DT (Rob) * Add clocksource driver Cc: Mark Rutland <mark.rutland@xxxxxxx> Cc: Arnd Bergmann <arnd@xxxxxxxx> Cc: Rob Herring <robh@xxxxxxxxxx> Cc: Daniel Lezcano <daniel.lezcano@xxxxxxxxxx> Cc: mp-cs@xxxxxxxxxxxxxxxx Cc: 96boards@xxxxxxxxxxxxxx Cc: support@xxxxxxxxxxx Cc: linux-serial@xxxxxxxxxxxxxxx Cc: linux-doc@xxxxxxxxxxxxxxx Cc: devicetree@xxxxxxxxxxxxxxx Andreas Färber (25): dt-bindings: Add vendor prefix for Actions Semi dt-bindings: arm: Document Actions Semi S500 dt-bindings: timer: Document Owl timer clocksource: Add Owl timer clocksource: owl: Add S900 support ARM: Prepare Actions Semi S500 ARM64: Prepare Actions Semi S900 dt-bindings: serial: Document Actions Semi Owl UARTs tty: serial: Add Actions Semi Owl UART earlycon Documentation: kernel-parameters: Document owl earlycon ARM: dts: Add Actions Semi S500 and LeMaker Guitar dt-bindings: Add vendor prefix for uCRobotics dt-bindings: arm: Document Actions Semi S900 ARM64: dts: Add Actions Semi S900 and Bubblegum-96 MAINTAINERS: Add Actions Semi Owl section tty: serial: owl: Implement console driver ARM64: dts: actions: s900-bubblegum-96: Add fake uart5 clock ARM: dts: s500-guitar-bb-rev-b: Add fake uart3 clock dt-bindings: arm: cpus: Add S500 enable-method ARM: owl: Implement CPU enable-method for S500 ARM: dts: s500: Set CPU enable-method dt-bindings: power: Add Owl SPS power domains soc: actions: Add Owl SPS ARM: dts: s500: Add SPS node ARM: owl: smp: Reimplement SPS power-gating for CPU2 and CPU3 Documentation/admin-guide/kernel-parameters.txt | 6 + Documentation/devicetree/bindings/arm/actions.txt | 39 ++ Documentation/devicetree/bindings/arm/cpus.txt | 1 + .../devicetree/bindings/power/actions,owl-sps.txt | 17 + .../bindings/serial/actions,owl-uart.txt | 16 + .../bindings/timer/actions,owl-timer.txt | 20 + .../devicetree/bindings/vendor-prefixes.txt | 2 + MAINTAINERS | 10 + arch/arm/Kconfig | 2 + arch/arm/Makefile | 1 + arch/arm/boot/dts/Makefile | 2 + arch/arm/boot/dts/s500-guitar-bb-rev-b.dts | 33 + arch/arm/boot/dts/s500-guitar.dtsi | 24 + arch/arm/boot/dts/s500.dtsi | 183 ++++++ arch/arm/mach-actions/Kconfig | 15 + arch/arm/mach-actions/Makefile | 2 + arch/arm/mach-actions/headsmp.S | 68 ++ arch/arm/mach-actions/owl.c | 28 + arch/arm/mach-actions/platsmp.c | 229 +++++++ arch/arm64/Kconfig.platforms | 6 + arch/arm64/boot/dts/Makefile | 1 + arch/arm64/boot/dts/actions/Makefile | 5 + arch/arm64/boot/dts/actions/s900-bubblegum-96.dts | 42 ++ arch/arm64/boot/dts/actions/s900.dtsi | 164 +++++ drivers/clocksource/Kconfig | 7 + drivers/clocksource/Makefile | 1 + drivers/clocksource/owl-timer.c | 205 ++++++ drivers/soc/Kconfig | 1 + drivers/soc/Makefile | 1 + drivers/soc/actions/Kconfig | 12 + drivers/soc/actions/Makefile | 1 + drivers/soc/actions/owl-sps.c | 245 +++++++ drivers/tty/serial/Kconfig | 19 + drivers/tty/serial/Makefile | 1 + drivers/tty/serial/owl-uart.c | 724 +++++++++++++++++++++ include/dt-bindings/power/s500-powergate.h | 19 + include/uapi/linux/serial_core.h | 3 + 37 files changed, 2155 insertions(+) create mode 100644 Documentation/devicetree/bindings/arm/actions.txt create mode 100644 Documentation/devicetree/bindings/power/actions,owl-sps.txt create mode 100644 Documentation/devicetree/bindings/serial/actions,owl-uart.txt create mode 100644 Documentation/devicetree/bindings/timer/actions,owl-timer.txt create mode 100644 arch/arm/boot/dts/s500-guitar-bb-rev-b.dts create mode 100644 arch/arm/boot/dts/s500-guitar.dtsi create mode 100644 arch/arm/boot/dts/s500.dtsi create mode 100644 arch/arm/mach-actions/Kconfig create mode 100644 arch/arm/mach-actions/Makefile create mode 100644 arch/arm/mach-actions/headsmp.S create mode 100644 arch/arm/mach-actions/owl.c create mode 100644 arch/arm/mach-actions/platsmp.c create mode 100644 arch/arm64/boot/dts/actions/Makefile create mode 100644 arch/arm64/boot/dts/actions/s900-bubblegum-96.dts create mode 100644 arch/arm64/boot/dts/actions/s900.dtsi create mode 100644 drivers/clocksource/owl-timer.c create mode 100644 drivers/soc/actions/Kconfig create mode 100644 drivers/soc/actions/Makefile create mode 100644 drivers/soc/actions/owl-sps.c create mode 100644 drivers/tty/serial/owl-uart.c create mode 100644 include/dt-bindings/power/s500-powergate.h -- 2.10.2 -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
