  • 0aa2eecf8   watchdog: rti-wdt: fix reference leak in rti_wdt_probe ... Browse Code »

    [ Upstream commit 8711071e9700b67045fe5518161d63f7a03e3c9e ]

    pm_runtime_get_sync() will increment pm usage counter even it
    failed. Forgetting to call pm_runtime_put_noidle will result
    in reference leak in rti_wdt_probe, so we should fix it.

    Common pattern of handling deferred probe can be simplified with
    dev_err_probe(). Less code and the error value gets printed.

    If the RTI watchdog is running already during probe, the driver must
    configure itself to match the HW. Window size and timeout is probed from
    hardware, and the last keepalive ping is adjusted to match it also.

    Texas Instruments K3 SoCs contain an RTI (Real Time Interrupt) module
    which can be used as a watchdog. This IP provides a support for
    windowed watchdog mode, in which the watchdog must be petted within
    a certain time window. If it is petted either too soon, or too late,
    a watchdog error will be triggered.
