X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7e2a1bcd2185c9d7d4c9b2910249a1a8fa841341;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ARM: dts: kzm9g: Configure NMI key as wake-up source

Add a GPIO key with wake-up capability for the NMI button.
This allows to wake up the system from s2ram without relying on the
buttons on the optional switch board.
