   4 Subject: arm64: dts: rockchip: Add vcc-supply to SPI flash on rk3588-rock-5b
   5
   6 The Radxa Rock 5B component placement document identifies the SPI Nor
   7 Flash chip as 'U4300' which is described on page 25 of the Schematic
   8 v1.45. There we can see that the VCC connector is connected to the
   9 VCC_3V3_S3 power source.

  11 This fixes the following warning:

  13   spi-nor spi5.0: supply vcc not found, using dummy regulator
