commit ea8500c3555647807154e28b870b23ddae7bd577

    wm97xx-core: Support use as a wakeup source
    
    The WM97xx touch screen controllers can be used to generate a wakeup
    event when the system is suspended. Provide a new core API call
    wm97xx_set_suspend_mode() allowing machine drivers to enable this. If no
    suspend_mode is provided then the touch panel will be powered down when
    the system is suspended.

commit 68e57dc88cdda110bfdbbcdeb79b0e18ba47452f

    wm97xx-core: Use IRQF_SAMPLE_RANDOM
    
    The touchscreen interrupt is driven by human input which can reasonably
    be used to provide entropy.

commit 5fa49e3357a66353cb2289b3ff0f3a4ab9f64c8e
Author: Mark Brown <broonie at opensource.wolfsonmicro.com>
Date:   Wed Apr 2 16:06:31 2008 +0100

    wm97xx-core: Only schedule interrupt handler if not already scheduled
    
    As well as clarifying the fact that the driver can cope if a second
    interrupt occurs before the IRQ work is scheduled this also ensures
    that calls to the machine irq_enable() are balanced, making that easier
    to implement.  Normally this is redundant due to the interrupt disabling
    but some unusal board configurations can trigger it.
