[PATCH 0/2] Add phy+vcc supply to NanoPi R5S and Q64-B

[Diederik de Haas]

Testing on my NanoPi R5S and Quartz64 Model B brought some more issues
with power supplies to light, so fix them as well.

[PATCH 1/2] arm64: dts: rockchip: Add phy-supply to gmac0 on NanoPi R5S

[Diederik de Haas]

According to paragraph "7.16. Power" of the RTL8211F-CG datasheet, gmac0
needs to have a 3.3V power supply.
On page 22 of the NanoPi R5S version 2204, that is identified as
VCC_GEPHY_3V3 which is connected to the VCC_3V3 power source.

This fixes the following warning:

  rk_gmac-dwmac fe2a0000.ethernet: supply phy not found, using dummy regulator

[PATCH 2/2] arm64: dts: rockchip: Add vcc-supply to SPI flash on rk3566-quartz64-b

[Diederik de Haas]

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
