The link from
  https://radxa.com/products/io-board/cm5-io-board#downloads
is
  https://dl.radxa.com/cm5/io_board_v2200/radxa_cm5_io_board_v2200_schematic.pdf.

(I think it's a mistake that the IO board schematic is under /v2200/, 
sorry!)

Node name should be '^regulator(-[0-9]+v[0-9]+|-[0-9a-z-]+)?$'.
Please see Documentation/devicetree/bindings/regulator/fixed-regulator.yaml.

According to the schematic, the name of the regulator controlled by 
GPIO1_A0 is VCC5V0_USB1, its power supply is VCC5V0_USB, and its power 
supply is VCC12V_DCIN.
Also, the name of GPIO1_A0 is USB_HOST_PWREN_H.

Node name should be '^regulator(-[0-9]+v[0-9]+|-[0-9a-z-]+)?$'.

The name of GPIO0_D5 is TYPEC5V_PWREN_H.

Is it VCC3V3_WF?

I think the regulator-name should be aligned with the node label.

pinctrl-* are missing.

Are the following properties required?

The power supply for VCC_3V3_S0 is VCC_3V3_S3.

I think dcdc-reg3, dcdc-reg4 and dcdc-reg5 should also be defined.

I think dcdc-reg9, dcdc-reg10, pldo-* and nldo-* should also be defined.

Should `vdd_cpu_lit_s0` and some others be in the SoM device tree instead of the IO board? I see it on page 18 of the schematic https://dl.radxa.com/cm5/v2210/radxa_cm5_v2210_schematic.pdf

Additionally, I am getting the following during boot:
```
[   38.190604] rockchip-pm-domain fd8d8000.power-management:power-controller: Failed to create device link (0x180) with supplier spi2.0 for /power-management@fd8d8000/power-controller/power-domain@12
```

The device is an RK3588s CM5 on the IO board powered through the barrel jack.

Sorry, I meant only the status property should go to the board DTS.
The rest of the gmac1 definition makes sense to put in the SoM dtsi,
since the PHY is on the SoM (as defined in  the mdio1 node). So all
the pins between the MAC and PHY will be the same.

Ah, thanks for the clarification. That's a small fixup, no worries.

Thanks for the feedback, I'll follow up.
