  • dcbb613fa   watchdog: bcm2835_wdt: drop platform_set_drvdata ... Browse Code »

    There is no call to platform_get_drvdata() in the driver,
    so platform_set_drvdata() is unnecessary and can be dropped.

    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

    The PM block that the wdt driver was binding to actually has multiple
    features we want to expose (power domains, reset, watchdog). Move the
    DT attachment to a MFD driver and make WDT probe against MFD.

  • 5f5aa6f10   watchdog: bcm2835_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.

    - Drop assignments to otherwise unused variables
    - Replace of_iomap() with platform_get_resource() followed by
    devm_ioremap_resource()
    - Replace &pdev->dev with dev if 'struct device *dev' is a declared
    variable
    - Use devm_watchdog_register_driver() to register watchdog device
    - Replace shutdown function with call to watchdog_stop_on_reboot()

  • 898e6861f   watchdog: bcm2835: Fix poweroff behaviour ... Browse Code »

    Currently poweroff/halt results in a reboot on the Raspberry Pi.
    The firmware uses the RSTS register to know which partiton to
    boot from. The partiton value is spread into bits
    0, 2, 4, 6, 8, 10. Partiton 63 is a special partition used by
    the firmware to indicate halt.

    The firmware made this change in 19 Aug 2013 and was matched
    by the downstream commit:
    Changes for new NOOBS multi partition booting from gsh

  • 6551881c8   Watchdog: Fix parent of watchdog_devices ... Browse Code »

    /sys/class/watchdog/watchdogn/device/modalias can help to identify the
    driver/module for a given watchdog node. However, many wdt devices do not
    set their parent and so, we do not see an entry for device in sysfs for
    such devices.

    This patch fixes parent of watchdog_device so that
    /sys/class/watchdog/watchdogn/device is populated.

    Exceptions: booke, diag288, octeon, softdog and w83627hf -- They do not
    have any parent. Not sure, how we can identify driver for these devices.

  • 8deea8306   watchdog: Remove unnecessary OOM messages ... Browse Code »

    The site-specific OOM messages are unnecessary, because they
    duplicate the MM subsystem generic OOM message. For example,
    k.alloc and v.alloc failures use dump_stack().

  • 487722cf2   watchdog: Get rid of MODULE_ALIAS_MISCDEV statements ... Browse Code »

    I just can't find any value in MODULE_ALIAS_MISCDEV(WATCHDOG_MINOR)
    and MODULE_ALIAS_MISCDEV(TEMP_MINOR) statements.

    Either the device is enumerated and the driver already has a module
    alias (e.g. PCI, USB etc.) that will get the right driver loaded
    automatically.

    Or the device is not enumerated and loading its driver will lead to
    more or less intrusive hardware poking. Such hardware poking should be
    limited to a bare minimum, so the user should really decide which
    drivers should be tried and in what order. Trying them all in
    arbitrary order can't do any good.

    On top of that, loading that many drivers at once bloats the kernel
    log. Also many drivers will stay loaded afterward, bloating the output
    of "lsmod" and wasting memory. Some modules (cs5535_mfgpt which gets
    loaded as a dependency) can't even be unloaded!

    If defining char-major-10-130 is needed then it should happen in
    user-space.
