[PATCH 1/4] arm64: dts: rockchip: Add vcc-supply to SPI flash on rk3328-rock64

From: Diederik de Haas
Date: Fri Apr 25 2025 - 05:27:03 EST


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")
