Subject: [PATCH] arm64: dts: rockchip: Add missing fan-supply to rk3566-quartz64-a
Date: Sat, 28 Jun 2025 16:28:18 +0200 [thread overview]
Message-ID: <20250628142843.839150-1-didi.debian@cknow.org> (raw)
The Quartz 64 Model-A Schematic from 20210427 on page 7 shows that the
fan's power supply is provided by VCC12V_DCIN.
This fixes the following warning:
gpio-fan gpio_fan: supply fan not found, using dummy regulator
