Subject: [PATCH 6/7] arm64: dts: rockchip: Add user button to Radxa E20C
Date: Fri, 28 Feb 2025 06:40:12 +0000	[thread overview]
Message-ID: <20250228064024.3200000-7-jonas@kwiboo.se> (raw)
In-Reply-To: <20250228064024.3200000-1-jonas@kwiboo.se>

Radxa E20C has two buttons, one SARADC maskrom button and one GPIO user
button.

Add support for the user button using a gpio-keys node.
