This patch series enhances the support for the SP805 watchdog timer. First of all, 'timeout-sec' devicetree property is added. In addition, support is also added to allow the driver to reset the watchdog if it has been detected that watchdot has been started in the bootloader. In this case, the driver will initiate the ping service from the kernel watchdog subsystem, before a user mode daemon takes over. This series also enables SP805 in the default ARM64 defconfig This patch series is based off v4.17-rc5 and is available on GIHUB: repo: https://github.com/Broadcom/arm64-linux.git branch: sp805-wdt-v1 Ray Jui (5): Documentation: DT: Add optional 'timeout-sec' property for sp805 watchdog: sp805: add 'timeout-sec' DT property support watchdog: sp805: set WDOG_HW_RUNNING when appropriate arm64: dt: set initial SR watchdog timeout to 60 seconds arm64: defconfig: add CONFIG_ARM_SP805_WATCHDOG .../devicetree/bindings/watchdog/sp805-wdt.txt | 2 ++ .../arm64/boot/dts/broadcom/stingray/stingray.dtsi | 1 + arch/arm64/configs/defconfig | 1 + drivers/watchdog/sp805_wdt.c | 31 +++++++++++++++++++++- 4 files changed, 34 insertions(+), 1 deletion(-) -- 2.1.4 -- 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
