  • 26c57ef1e   watchdog: New watchdog driver for MEN A21 watchdogs ... Browse Code »

    This patch adds the driver for the watchdog devices found on MEN Mikro
    Elektronik A21 VMEbus CPU Carrier Boards. It has DT-support and uses the
    watchdog framework.

  • 6e63a3a29   watchdog: delete mpcore_wdt driver ... Browse Code »

    Interrupt request doesn't use the right API: The TWD watchdog uses a per-cpu
    interrupt (usually interrupt #30), and the GIC configuration should flag it as
    such. With this setup, request_irq() should fail, and the right API is
    request_percpu_irq(), together with enable_percpu_irq()/disable_percpu_irq().

    Nothing ensures the userspace ioctl() will end-up kicking the watchdog on the
    right CPU.

    There are no users of this driver since a long time and it makes more sense to
    get rid of it as nobody is looking to fix it.

    In case somebody wakes up after this has been removed and needs it, please
    revert this driver and pick these updates (These were never pushed to mainline):

  • de6303ab9   watchdog: add new driver for STMP3xxx and i.MX23/28 ... Browse Code »

    Replace the existing STMP3xxx driver because it has enough drawbacks
    that a rewrite is apropriate. The new driver is designed to use the
    watchdog framework which makes it a lot smaller and avoids open coding
    the watchdog API again. It also uses now an explicitly exported function
    from the RTC driver to set up its registers (the old driver silently
    reused the hopefully(!) already remapped RTC registers). Also, this
    driver is mach independent, while the old one depends on a mach replaced
    by another one a year ago. Since the user interface is still the
    standard watchdog API, users don't need to adapt.

  • 43316044d   watchdog: WatchDog Timer Driver Core - Add basic framework ... Browse Code »

    The WatchDog Timer Driver Core is a framework
    that contains the common code for all watchdog-driver's.
    It also introduces a watchdog device structure and the
    operations that go with it.

    This is the introduction of this framework. This part
    supports the minimal watchdog userspace API (or with
    other words: the functionality to use /dev/watchdog's
    open, release and write functionality as defined in
    the simplest watchdog API). Extra functionality will
    follow in the next set of patches.

    Watchdog timer device driver for Xilinx xps_timebase_wdt compatible ip cores.
    It takes watchdog timer configuration from device tree and it needs that its
    parent has defined the property "clock-frecuency".
    It is compatible with watchdog timer kernel API, so user apps like watchdogd
    may talk with it.

  • 066d6c7f4   watchdog: Xen watchdog driver ... Browse Code »

    While the hypervisor change adding SCHEDOP_watchdog support included a
    daemon to make use of the new functionality, having a kernel driver
    for /dev/watchdog so that user space code doesn't need to distinguish
    non-Xen and Xen seems to be preferable.

  • 57539c1cf   watchdog: Intel SCU Watchdog Timer Driver for Moorestown and Medfield platforms. ... Browse Code »

    This submission includes:
    - Fix to intel_scu_write() to start watchdog timer the on the
    first write, and refresh on subsequent writes.
    This enables Open, write, write, ... usage model.
    - Moves boot parameter checks from intel_scu_open() to
    intel_scu_watchdog_init(), so driver init will fail if these
    parameters are out of bounds.
    - Adds check for whether process waiting in wait_event_interruptible()
    received a signal while it was waiting.
    - Other small error handling changes.

    Removed the read() method for now as that wass a non-standard behaviour.

  • 4c076fb41   WATCHDOG: Add watchdog driver for OCTEON SOCs ... Browse Code »

    The OCTEON is a MIPS64 based SOC family with an on chip watchdog unit.

    The driver is split into two source files one for the C code and one
    for assembly. Assembly is needed to handle the NMI and then print the
    machine state before the reboot is triggered.
