Subject: [PATCH v4 09/11] arm64: dts: freescale: sl28: map GPIOs to input events
Date: Thu,  4 Jun 2020 23:10:37 +0200
Message-ID: <20200604211039.12689-10-michael@walle.cc> (raw)
In-Reply-To: <20200604211039.12689-1-michael@walle.cc>

Now that we have support for GPIO lines of the SMARC connector, map the
sleep, power and lid switch signals to the corresponding keys using the
gpio-keys and gpio-keys-polled drivers. The power and sleep signals have
dedicated interrupts, thus we use these ones. The lid switch is just
mapped to a GPIO input and needs polling.
