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

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

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

Should be 3.3v not 3.0v?

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.

Schematics use vcc5v_hdmi_tx for the HDMI +5V pin.

This should be vcc5v0_sys_s5.

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

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