Third patchset to extend Orion watchdog driver adding support for Armada 370/XP SoC. This consists on a small incremental series. Please take a look at the previous version and the discussion raised: http://www.spinics.net/lists/arm-kernel/msg302104.html Changes from v2: * Add proper error checking on clk_prepare_enable() and return PTR_ERR instead of ENODEV. Suggested by Fabio Estevam. * After the usage of the atomic I/O and considering the watchdog core does its own serialization, the driver's spinlock was completely redundant and was removed. Also suggested by Fabio. * Instead of making the driver dependent on PLAT_ORION, added a dependency to ARCH_MVEBU. This was proposed by Sebastian and Andrew, given we're working on PLAT_ORION removal. This series is based on v3.13-rc8 and has been tested on: * Marvell's Armada XP GP board Ezequiel Garcia (15): ARM: Introduce atomic MMIO modify clocksource: orion: Use atomic access for shared registers watchdog: orion: Use atomic access for shared registers watchdog: orion: Handle IRQ watchdog: orion: Make RSTOUT register a separate resource watchdog: orion: Remove unneeded BRIDGE_CAUSE clear watchdog: orion: Introduce an orion_watchdog device structure watchdog: orion: Introduce per-compatible of_device_id data watchdog: orion: Add per-compatible clock initialization watchdog: orion: Add per-compatible watchdog start implementation watchdog: orion: Add support for Armada 370 and Armada XP SoC ARM: mvebu: Enable Armada 370/XP watchdog in the devicetree ARM: kirkwood: Add RSTOUT 'reg' entry to devicetree watchdog: orion: Enable the build on ARCH_MVEBU ARM: mvebu: Enable watchdog support in defconfig .../devicetree/bindings/watchdog/marvel.txt | 8 +- arch/arm/boot/dts/armada-370-xp.dtsi | 4 + arch/arm/boot/dts/armada-370.dtsi | 5 + arch/arm/boot/dts/armada-xp.dtsi | 6 + arch/arm/boot/dts/kirkwood.dtsi | 2 +- arch/arm/configs/mvebu_defconfig | 2 + arch/arm/include/asm/io.h | 6 + arch/arm/kernel/io.c | 35 +++ arch/arm/mach-dove/include/mach/bridge-regs.h | 1 + arch/arm/mach-kirkwood/include/mach/bridge-regs.h | 1 + arch/arm/mach-mv78xx0/include/mach/bridge-regs.h | 1 + arch/arm/mach-orion5x/include/mach/bridge-regs.h | 1 + arch/arm/plat-orion/common.c | 10 +- drivers/clocksource/time-orion.c | 28 +- drivers/watchdog/Kconfig | 2 +- drivers/watchdog/orion_wdt.c | 320 ++++++++++++++++----- 16 files changed, 329 insertions(+), 103 deletions(-) -- 1.8.1.5 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
