Hello, This series adds initial support for Actions Semiconductor S500 (ARMv7) and S900 (ARMv8) SoCs. In addition to earlycon serial output, v2 includes a serial console driver RFC. Guitar output is coming further along thanks to a new timer implementation, but is still earlycon only - to be investigated. Bubblegum-96 reaches an initrd, but a small part of the serial output just before is lost (visible in dmesg). 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 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@arm.com> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Rob Herring <robh@kernel.org> Cc: mp-cs@actions-semi.com Cc: 96boards@ucrobotics.com Cc: support@lemaker.org Cc: devicetree@vger.kernel.org Andreas Färber (17): 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 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 clk ARM: dts: s500-guitar-bb-rev-b: Add fake uart3 clock Documentation/admin-guide/kernel-parameters.txt | 6 + Documentation/devicetree/bindings/arm/actions.txt | 39 ++ .../bindings/serial/actions,owl-uart.txt | 16 + .../bindings/timer/actions,owl-timer.txt | 16 + .../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 | 20 + arch/arm/boot/dts/s500.dtsi | 135 ++++ arch/arm/mach-actions/Kconfig | 10 + arch/arm/mach-actions/Makefile | 1 + arch/arm/mach-actions/owl.c | 28 + arch/arm64/Kconfig.platforms | 5 + arch/arm64/boot/dts/Makefile | 1 + arch/arm64/boot/dts/actions/Makefile | 5 + arch/arm64/boot/dts/actions/s900-bubblegum-96.dts | 38 ++ arch/arm64/boot/dts/actions/s900.dtsi | 109 ++++ drivers/clocksource/Kconfig | 7 + drivers/clocksource/Makefile | 1 + drivers/clocksource/owl-timer.c | 146 +++++ drivers/tty/serial/Kconfig | 19 + drivers/tty/serial/Makefile | 1 + drivers/tty/serial/owl-uart.c | 707 +++++++++++++++++++++ include/uapi/linux/serial_core.h | 3 + 27 files changed, 1363 insertions(+) create mode 100644 Documentation/devicetree/bindings/arm/actions.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/owl.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/tty/serial/owl-uart.c -- 2.10.2
