  • d2a10c312   watchdog: lpc18xx_wdt: Convert to use device managed functions and other improvements ... Browse Code »

    Use device managed functions to simplify error handling, reduce
    source code size, improve readability, and reduce the likelyhood of bugs.
    Other improvements as listed below.

    The conversion was done automatically with coccinelle using the
    following semantic patches. The semantic patches and the scripts
    used to generate this commit log are available at
    https://github.com/groeck/coccinelle-patches

    - Use devm_add_action_or_reset() for calls to clk_disable_unprepare
    - Use local variable 'struct device *dev' consistently
    - Use devm_watchdog_register_driver() to register watchdog device
    - Replace shutdown function with call to watchdog_stop_on_reboot()

  • d1cadcb7c   watchdog: lpc18xx_wdt: Convert timers to use timer_setup() ... Browse Code »

    In preparation for unconditionally passing the struct timer_list pointer to
    all timer callbacks, switch to using the new timer_setup() and from_timer()
    to pass the timer pointer explicitly.

  • 6c368932f   watchdog: constify watchdog_info structures ... Browse Code »

    Declare watchdog_info structures as const as they are only stored in the
    info field of watchdog_device structures. This field is of type const
    struct watchdog_info *, so watchdog_info structures having this property
    can be declared const too.
    Done using Coccinelle:

    @r1 disable optional_qualifier@

  • 7c25f8c9f   watchdog: NXP LPC18xx Watchdog Timer Driver ... Browse Code »

    This commit adds support for the watchdog timer found in NXP LPC SoCs
    family, which includes LPC18xx/LPC43xx. Other SoCs in that family may
    share the same watchdog hardware.

    Watchdog driver registers a restart handler that will restart the system
    by performing an incorrect feed after ensuring the watchdog is enabled in
    reset mode.

    As watchdog cannot be disabled in hardware, driver's stop routine will
    regularly send a keepalive ping using a timer.
