    Subject[PATCH 3.16 023/305] ARM: dts: exynos: Disable pull control for MAX8997 interrupts on Origen
    3.16.63-rc1 review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Marek Szyprowski <m.szyprowski@samsung.com>

    commit f5e758b8358f6c27e8a351ddf0b441a64cdabb94 upstream.

    PMIC_IRQB and PMIC_KEYINB lines on Exynos4210-based Origen board have
    external pull-up resistors, so disable any pull control for those lines
    in respective pin controller node. This fixes support for MAX8997
    interrupts and enables operation of wakeup from MAX8997 RTC alarm.

    Fixes: 17419726aaa1 ("ARM: dts: add max8997 device node for exynos4210-origen board")
    Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
    [bwh: Backported to 3.16:
    - Use literal 0 instead of EXYNOS_PIN_PULL_NONE
    - Adjust context, indentation]
