[PATCH 4.9 038/222] ARM: dts: exynos: Disable pull control for S5M8767 PMIC

[Greg Kroah-Hartman]

From: Marek Szyprowski <m.szyprowski@xxxxxxxxxxx>

[ Upstream commit ef2ecab9af5feae97c47b7f61cdd96f7f49b2c23 ]

S5M8767 PMIC interrupt line on Exynos5250-based Arndale board has
external pull-up resistors, so disable any pull control for it in
in controller node. This fixes support for S5M8767 interrupts and
enables operation of wakeup from S5M8767 RTC alarm.
