I would add the following to end of arch/arm64/Kconfig.platforms, and
add the
modification to this patch series.
config ARCH_MA35D1
bool "Nuvoton MA35D1 SOC Family"
select PINCTRL
select PINCTRL_MA35D1
select PM
select GPIOLIB
select SOC_BUS
select VIDEOMODE_HELPERS
select FB_MODE_HELPERS
help
This enables support for Nuvoton MA35D1 SOC Family.

OK, I would modify it as:
chosen {
stdout-path = "serial0:115200n8";
};

> You need compatible and bindings.
I will add the compatible here
compatible = "nuvoton,ma35d1-evb", "nuvoton,ma35d1"
And, I should create a new binding file
Documentation/devicetree/bindings/arm/nuvoton.yaml to this patch series.
And the property would be:
properties:
compatible:
description: Nuvoton MA35D1-EVB
items:
- const: nuvoton,ma35d1-evb
- const: nuvoton,ma35d1
Is it OK?

I will create a new binding file

OK, I will fix it in the next version.

I am sorry. I have requested mail server manager to add exception rule.
The unpleasant official declarations are removed.
Thanks for your review.
Sincerely,
