ARM: dts: exynos: Disable pull control for MAX8997 interrupts on Origen
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.
