[PATCH] arm64: dts: rockchip: Add vcc-supply to SPI flash on Pinephone Pro

Posted by Peter Robinson 5 months, 2 weeks ago

As documented in the PinephonePro-Schematic-V1.0-20211127.pdf,
page 11, the SPI Flash's VCC pin is connected to VCC_1V8 power
source. This fixes the following warning:

  spi-nor spi1.0: supply vcc not found, using dummy regulator
