Subject: [PATCH 1/4] arm64: dts: rockchip: Add vcc-supply to SPI flash on rk3328-rock64
Date: Fri, 25 Apr 2025 10:44:41 +0200 [thread overview]
Message-ID: <20250425092601.56549-2-didi.debian@cknow.org> (raw)
In-Reply-To: <20250425092601.56549-1-didi.debian@cknow.org>
As described on page 6 of the Rock64 schematics for both v2.0 and v3.0
the SPI Flash's VCC connector is connected to the VCC_IO power source.
This fixes the following warning:
spi-nor spi0.0: supply vcc not found, using dummy regulator
Fixes: e7f4e924f46d ("dt-bindings: mtd: jedec,spi-nor: add optional vcc-supply")
