    Pull timer fixes from Thomas Gleixner:
    "A rather small update for the time(r) subsystem:

    - A new clocksource driver IMX-TPM

    - Minor fixes to the alarmtimer facility

    - Device tree cleanups for Renesas drivers

    - A new kselftest and fixes for the timer related tests

    - Conversion of the clocksource drivers to use %pOF

    - Use the proper helpers to access rlimits in the posix-cpu-timer
    code"

    Now that we have a custom printf format specifier, convert users of
    full_name to use %pOF instead. This is preparation to remove storing
    of the full path string for each node.

  • 9e80dbd87   clocksource/drivers/timer-of: Checking for IS_ERR() instead of NULL ... Browse Code »

    The current code checks the return value of the of_io_request_and_map()
    function as it was returning a NULL pointer in case of error.

    However, it returns an error code encoded in the pointer return value, not a
    NULL value. Fix this by checking the returned pointer against IS_ERR() and
    return the error with PTR_ERR().

  • 32f2fea6e   clocksource/drivers/timer-of: Handle of_irq_get_byname() result correctly ... Browse Code »

    of_irq_get_byname() may return a negative error number as well as 0 on
    failure, while timer_irq_init() only checks for 0, blithely continuing with
    the call to request_[percpu_]irq() -- those functions expect *unsigned int*,
    so would probably fail anyway when a large IRQ number resulting from a
    conversion of a negative error number is passed to them... This, however,
    is incorrect behavior -- error number is not IRQ number.

    Filter out the negative error numbers, complain, and return them to the
    timer_irq_init()'s callers...

  • b7dcc4eac   clocksource/drivers: Fix uninitialized variable use in timer_of_init ... Browse Code »

    If none of the flags are set, 'ret' is uninitialized as pointed out
    by gcc:

    drivers/clocksource/timer-of.c: In function 'timer_of_init':
    drivers/clocksource/timer-of.c:160:9: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]

    Since calling the function without any of the flags is an error,
    set the return value to -EINVAL for that case.

    [ tglx: Get rid of the silly backwards goto while at it ]

    The different drivers are all using the same pattern when initializing.

    1. Get the base address
    2. Get the irq number
    3. Get the clock
    4. Prepare and enable the clock
    5. Get the rate
    6. Request an interrupt

    Instead of repeating again and again these steps in all the drivers, let's
    provide a common init routine to give the opportunity to factor all of them
    out.

    We can expect a significant kernel size improvement when the common routine
    will be used in all the drivers.
