Great, I was about to send out a similar device tree patch for this
board, below you find a few remarks.

The marketing name seems to be "Radxa ROCK 3C" according to the product
page at [1].

[1] https://radxa.com/products/rock3/3c

> +	compatible = "radxa,rock3c", "rockchip,rk3566";

A personal preference would be to match the product name and the dtb
filename, e.g. "radxa,rock-3c".

This is called user_led2 in the schematic, in case we want the symbol to
match the schematic.

This regulator is named vcc5v0_usb30_host in schematic.

I think clock-output-names may be missing? Something like:

  clock-output-names = "rk809-clkout1", "rk809-clkout2";

I think this prop is deprecated and system-power-controller should be
used instead.

Not sure we need this in suspend to ram and this can probably use:

  regulator-off-in-suspend

That is also what vendor kernel does.

If I am reading the schematic correctly this is not connected.

This should probably use a space instead of a tab after =.

This board support HS200, please add:

  mmc-hs200-1_8v

Please drop the cd-gpios prop, sdmmc0_det is used below and works fine
on this board.

Why limit to sdr50? and not use sd-uhs-sdr104?

If I read the scematics correctly this is using the vcc3v3_sys regulator
and not the vcc3v3_sd. R90724 is not connected however R90723 is and
this also matches visual inspection of the board.

This is missing pinctrl:

  pinctrl-names = "default";
  pinctrl-0 = <&fspi_pins>;

My board is using a GD25LQ128EWIGR same as mentioned in the schematic,
and datasheet for this flash chip menion 120 mhz and not 104 mhz.
