In the Quartz 64 Model-B Schematic from 20220124 on page 17, we can see that the VCC connector is connected to VCCIO_FLASH and page 4 shows that that in turn is connected to the VCCIO2 domain. That domain uses vcc_1v8 as its power source. This fixes the following warning: spi-nor spi4.0: supply vcc not found, using dummy regulator Signed-off-by: Diederik de Haas --- arch/arm64/boot/dts/rockchip/rk3566-quartz64-b.dts | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/arm64/boot/dts/rockchip/rk3566-quartz64-b.dts b/arch/arm64/boot/dts/rockchip/rk3566-quartz64-b.dts index 5707321a1144..f8cf03380636 100644 --- a/arch/arm64/boot/dts/rockchip/rk3566-quartz64-b.dts +++ b/arch/arm64/boot/dts/rockchip/rk3566-quartz64-b.dts @@ -648,6 +648,7 @@ flash@0 { spi-max-frequency = <24000000>; spi-rx-bus-width = <4>; spi-tx-bus-width = <1>; + vcc-supply = <&vcc_1v8>; }; }; -- 2.49.0
