Subject: [PATCH v6 10/13] arm64: dts: freescale: sl28: map GPIOs to input events
Date: Sun, 26 Jul 2020 01:18:31 +0200 [thread overview]
Message-ID: <20200725231834.25642-11-michael@walle.cc> (raw)
In-Reply-To: <20200725231834.25642-1-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.
