No need for input.h, leds/common.h and boot-mode.h.

Please remove the tx_delay and rx_delay, it's useless.
I know there is an error log, but please ignore it first.

obviously (

I tend to write like this:

```
&pinctrl {
	wifi {
		wifi_reg_on_h: wifi-reg-on-h {
```

Overwrite original to match `sdmmc0_pwren`

sdmmc0 {
	sdmmc0_pwren: sdmmc0-pwren {

Extra blank lines.

`max-frequency = <150000000>;` already defined in rk356x.dtsi

Same for usb_host1

Is usb2phy1_host connected?
