Hi everyone, This patchset add support in Linux for the Allwinner A31 SoC. This SoC is the current high-end Allwinner SoC, and is powered by 4 Cortex-A7.
SMP support is not there yet, but should come eventually, so does the clock support. As usual, since we don't have any storage device driver yet, it only boots from an initramfs. Finally, something worth mentionning is that with the current bootloader, you'll encounter 2 ~6s hangs during the boot. This is because the SMP bit of the Cortex-A7 doesn't appear to be set, leading to the CPU caches being disabled. This can partially be addressed by selecting CONFIG_SMP, that will remove the second hang, because the SMP bit is set after kernel decompression. Obviously, this won't remove the first hang that happens during decompression, but it's better than nothing. A proper fix would be to fix the bootloader. Thanks, Maxime Changes from v1: - Used the GIC bindings for the virtualization extensions available in the Cortex-A7 - Cosmetic changes on the interrupts definitions - Removed the reg property in the soc bus - Fixed a bug squashing issue when adding the A31 dtsi - Added the A31 watchdog compatible to the binding documentation - Used the BIT macro in the restart code - Fix a few errors/typos in the commit logs Emilio López (1): clk: sunxi: fix initialization of basic clocks Maxime Ripard (9): irqchip: GIC: Add Cortex-A7 compatible string ARM: sunxi: Add the Allwinner A31 compatible to the machine definition ARM: sun6i: Add restart code for the A31 ARM: sunxi: Add Allwinner A31 DTSI ARM: sun6i: Add WITS Colombus A31 evaluation kit support pinctrl: sunxi: Add Allwinner A31 pins set ARM: sunxi: dt: Add PIO controller to A31 DTSI ARM: sun6i: Add UART0 muxing options ARM: sun6i: colombus: Add uart0 muxing .../devicetree/bindings/watchdog/sun4i-wdt.txt | 13 - .../devicetree/bindings/watchdog/sunxi-wdt.txt | 14 + arch/arm/boot/dts/Makefile | 3 +- arch/arm/boot/dts/sun6i-a31-colombus.dts | 32 + arch/arm/boot/dts/sun6i-a31.dtsi | 175 +++++ arch/arm/mach-sunxi/Kconfig | 2 + arch/arm/mach-sunxi/sunxi.c | 44 +- drivers/clk/sunxi/clk-sunxi.c | 11 +- drivers/irqchip/irq-gic.c | 1 + drivers/pinctrl/pinctrl-sunxi-pins.h | 820 +++++++++++++++++++++ drivers/pinctrl/pinctrl-sunxi.c | 1 + 11 files changed, 1091 insertions(+), 25 deletions(-) delete mode 100644 Documentation/devicetree/bindings/watchdog/sun4i-wdt.txt create mode 100644 Documentation/devicetree/bindings/watchdog/sunxi-wdt.txt create mode 100644 arch/arm/boot/dts/sun6i-a31-colombus.dts create mode 100644 arch/arm/boot/dts/sun6i-a31.dtsi -- 1.8.3.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
