Subject: [PATCH 10/12] ARM: dts: mmp3-dell-ariel: Add the power button node
Date: Thu, 21 Jan 2021 04:41:28 +0100 [thread overview]
Message-ID: <20210121034130.1381872-11-lkundrak@v3.sk> (raw)
In-Reply-To: <20210121034130.1381872-1-lkundrak@v3.sk>
This adds support for the power button attached to the Embedded Controller
on a Dell Wyse 3020 "Ariel" board.
However, while the EC itself is controlled via I2C, the input capability
for the power button acts as a separate device attached to the SPI, hence
it has a separate device node.
