usr_button is used in schematics, maybe usr_button_pin?

Please use color and function props, you can skip label or use SYS as
printed on the board.

Schematic use led_sys_h for this pin.

Same as above, use color and function props, this is named LED2.

This is named 6~20v_dcin or vcc12v_dcin in schematics.

Is all these regulator-state-mem nodes needed for regulator-fixed?

This is called pcie0_pwren_h in schematic.

This is named vcc3v3_m2_keym in schematic.

Should be 3.3v not 3.0v?

This is called vcc3v3_sd_s0 in schematic.

I cannot find this regulator in the schematic, only vcc5v0_sys_s5.

This is used to switch between HDMI2.0(TMDS) and HDMI2.1(FRL) mode, and
should probably not be modeled as a regulator.

This is called pcie0_perstn in schematic.

This is default for the SoC so this can be dropped.

Please use the <&sdmmc0_clk>, <&sdmmc0_cmd>, <&sdmmc0_det>,
<&sdmmc0_bus4> format, will include more schemantic information for
parsers.

Same here.

For U-Boot I tested with 50 MHz, any reason why this is so low?
Please check datasheet for the SPI-flash module.
