Subject: ARM: dts: exynos: Add pinctrl config for Midas keys
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=492413dd6d19448c40e2ac946b65f8e60dd306e1;p=linux.git

ARM: dts: exynos: Add pinctrl config for Midas keys

This pins are externally pulled up, and so we should explicitly
configure them to disable the SoC-internal pull-downs. Previously
we relied on the bootloader doing this in order to allow the buttons
to function properly.
