Hi, This series introduce the support of the Armada 3700 family: it is the first ARM64 SoC of the mvebu family submitted to the mainline!
Currently there are two members of the Armada 3700 family, the only difference is the number of core: the Armada 3710 comes with one Cortex-A53 whereas the Armada 3720 comes with 2 Cortex-A53. In this series we enabled only the minimum to boot, pinctrl and clock tree will come soon. This is the second version of the series, see the changelog for the detail. The bigger change was the addition of two itqchip patches to be able to use the the ARCH_MVEBU for the Armada 3700 SoCs. The first ones is only here to have standalone series but it comes from Thomas Petazzoni's series: http://thread.gmane.org/gmane.linux.ports.arm.kernel/472625 Then on top of it I added a small patch allowing building the kernel without this driver for ARM64. So now there is a dependency :/ Besides this the patches are pretty usual: The third patch introduces a new serial driver for the uart used on this SoC. The driver remains simple even if the hardware is capable of doing more. The forth one adapts the ahci driver to support the Armada 3700 SoC. The forth patch updates the binding documentation with the new compatible string. The fifth patch adds a new entry Kconfig entry for this SoC family. I took the opportunity of this series to tidy up the Marvell related files in the binding documentation with the seventh patch. The eighth patch introduces the compatible string for the SoCs of the Armada 3700 family. The ninth patch could be considered as the bulk of this series: it adds the device tree files for the Armada 3700 SoCs and for the reference board. With the introduction of this new family the MAINTAINERS file, the Marvell README and the ARM64 defconfig files have to be updated: it is the purpose of the last 3 patches. The patches 3 and 4 could be taken directly by the maintainer of their respective subsystem as there is no dependency at all with the rest of the series. I think that the rest of the series should go through the arm-soc maintainer but in doubt I also added the ARM64 maintainer as suggested by get_maintainer.pl. Thanks, Gregory Changelog: v1 -> v2 - Added Rob acked-by on patches 3, 6 and 7 - Used armada3700_uart instead of mvebu_uart for the uart driver: suggested by Mark - In mvebu-uart, do not use anymore TTY_MAJOR, or ttyS, but dynamic major and ttyMV: pointed by Alan - Use tty_termios_copy_hw in mvebu_uart_set_termios: suggested by Alan - Use ARCH_MVEBU instead of creating ARCH_ARMADA_3700: suggested by Jisheng - Added a new irqchip pacthes to fix build on ARM64 when ARCH_MVEBU is selected - Removed marvell,armada3700 from the device tree binding and directly used marvell,armada3710 for common feature: pointed by Rob - Fix memory node with coorect size in armada-3720-db.dts: suggested by Mark Gregory CLEMENT (9): irqchip: armada-370-xp: do not enable it by default when ARCH_MVEBU is selected arm64: add mvebu architecture entry Documentation: dt-bindings: Add a new compatible for the Armada 3700 Documentation: dt: Tidy up the Marvell related files devicetree: bindings: add DT binding for the Marvell Armada 3700 SoC family arm64: dts: add the Marvell Armada 3700 family and a development board MAINTAINERS: Extend dts entry for ARM64 mvebu files Documentation: arm: update supported Marvell EBU processors arm64: defconfig: enable Armada 3700 related config Lior Amsalem (1): ata: ahci_mvebu: add support for Armada 3700 variant Thomas Petazzoni (1): irqchip: armada-370-xp: add Kconfig option for the driver Wilson Ding (1): serial: mvebu-uart: initial support for Armada-3700 serial port Documentation/arm/Marvell/README | 13 + .../arm/{ => marvell}/armada-370-xp-pmsu.txt | 0 .../bindings/arm/{ => marvell}/armada-370-xp.txt | 0 .../bindings/arm/{ => marvell}/armada-375.txt | 0 .../bindings/arm/marvell/armada-37xx.txt | 16 + .../{ => marvell}/armada-380-mpcore-soc-ctrl.txt | 0 .../bindings/arm/{ => marvell}/armada-38x.txt | 0 .../bindings/arm/{ => marvell}/armada-39x.txt | 0 .../arm/{ => marvell}/armada-cpu-reset.txt | 0 .../arm/{ => marvell}/coherency-fabric.txt | 0 .../bindings/arm/{ => marvell}/kirkwood.txt | 0 .../bindings/arm/{ => marvell}/marvell,berlin.txt | 0 .../bindings/arm/{ => marvell}/marvell,dove.txt | 0 .../arm/{ => marvell}/marvell,kirkwood.txt | 0 .../arm/{ => marvell}/mvebu-cpu-config.txt | 0 .../arm/{ => marvell}/mvebu-system-controller.txt | 0 .../devicetree/bindings/ata/ahci-platform.txt | 1 + .../devicetree/bindings/tty/serial/mvebu-uart.txt | 13 + Documentation/kernel-parameters.txt | 6 + MAINTAINERS | 1 + arch/arm64/Kconfig.platforms | 6 + arch/arm64/boot/dts/marvell/Makefile | 4 + arch/arm64/boot/dts/marvell/armada-371x.dtsi | 53 ++ arch/arm64/boot/dts/marvell/armada-3720-db.dts | 86 +++ arch/arm64/boot/dts/marvell/armada-372x.dtsi | 63 ++ arch/arm64/boot/dts/marvell/armada-37xx.dtsi | 131 +++++ arch/arm64/configs/defconfig | 5 + drivers/ata/ahci_mvebu.c | 14 +- drivers/irqchip/Kconfig | 4 + drivers/irqchip/Makefile | 2 +- drivers/tty/serial/Kconfig | 22 + drivers/tty/serial/Makefile | 1 + drivers/tty/serial/mvebu-uart.c | 650 +++++++++++++++++++++ include/uapi/linux/serial_core.h | 3 + 34 files changed, 1088 insertions(+), 6 deletions(-) rename Documentation/devicetree/bindings/arm/{ => marvell}/armada-370-xp-pmsu.txt (100%) rename Documentation/devicetree/bindings/arm/{ => marvell}/armada-370-xp.txt (100%) rename Documentation/devicetree/bindings/arm/{ => marvell}/armada-375.txt (100%) create mode 100644 Documentation/devicetree/bindings/arm/marvell/armada-37xx.txt rename Documentation/devicetree/bindings/arm/{ => marvell}/armada-380-mpcore-soc-ctrl.txt (100%) rename Documentation/devicetree/bindings/arm/{ => marvell}/armada-38x.txt (100%) rename Documentation/devicetree/bindings/arm/{ => marvell}/armada-39x.txt (100%) rename Documentation/devicetree/bindings/arm/{ => marvell}/armada-cpu-reset.txt (100%) rename Documentation/devicetree/bindings/arm/{ => marvell}/coherency-fabric.txt (100%) rename Documentation/devicetree/bindings/arm/{ => marvell}/kirkwood.txt (100%) rename Documentation/devicetree/bindings/arm/{ => marvell}/marvell,berlin.txt (100%) rename Documentation/devicetree/bindings/arm/{ => marvell}/marvell,dove.txt (100%) rename Documentation/devicetree/bindings/arm/{ => marvell}/marvell,kirkwood.txt (100%) rename Documentation/devicetree/bindings/arm/{ => marvell}/mvebu-cpu-config.txt (100%) rename Documentation/devicetree/bindings/arm/{ => marvell}/mvebu-system-controller.txt (100%) create mode 100644 Documentation/devicetree/bindings/tty/serial/mvebu-uart.txt create mode 100644 arch/arm64/boot/dts/marvell/armada-371x.dtsi create mode 100644 arch/arm64/boot/dts/marvell/armada-3720-db.dts create mode 100644 arch/arm64/boot/dts/marvell/armada-372x.dtsi create mode 100644 arch/arm64/boot/dts/marvell/armada-37xx.dtsi create mode 100644 drivers/tty/serial/mvebu-uart.c -- 2.5.0
