Subject: [PATCH 1/2] arm64: dts: rockchip: add LED for ROCK Pi 4A/B/C/A+/B+
Date: Wed, 7 Sep 2022 04:59:24 +0000 [thread overview]
Message-ID: <20220907045925.1284785-1-naoki@radxa.com> (raw)
only user_led2 (blue) is supported.
user_led1 (green) is not connected to any gpio so it cannot be
controlled.
