Subject: [PATCH 1/1] arm64: dts: meson-sm1-sei610: gpio-keys: switch to IRQs
Date: Thu, 21 Nov 2019 10:37:11 -0800 [thread overview]
Message-ID: <20191121183711.19785-1-khilman@kernel.org> (raw)
From: Kevin Hilman <khilman@baylibre.com>
Switch the GPIO buttons/switches to use interrupts instead of polling.
While at it, add the mic mute switch and the power button.
