Subject: [PATCH v3 0/6] Enhance support for the SP805 WDT
Date: Wed, 23 May 2018 17:15:18 -0700 [thread overview]
Message-ID: <1527120924-12131-1-git-send-email-ray.jui@broadcom.com> (raw)
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-v3
Changes since v2:
- Fix indent and format to make them consistent within arm,sp805.txt
Changes since v1:
- Consolidate two duplicated SP805 binding documents into one
- Slight change of the wdt_is_running implementation per discussion
