From ec79aee752c6b5c7695cd82a57a8a9249d09316d Mon Sep 17 00:00:00 2001 From: Diederik de Haas Date: Sat, 3 May 2025 17:22:19 +0200 Subject: [PATCH] arm64: dts: rockchip: Add vcc-supply to SPI flash on rk3566-quartz64-b The Quartz64 Model B has a Winbound 25Q64DWZPIG SPI flash chip, identified as 'U13' on the component placement schematic. 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 Link: https://lore.kernel.org/r/20250503152917.138648-3-didi.debian@cknow.org Signed-off-by: Heiko Stuebner --- 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 @@ spi-max-frequency = <24000000>; spi-rx-bus-width = <4>; spi-tx-bus-width = <1>; + vcc-supply = <&vcc_1v8>; }; }; -- 2.50.1
