We do not add options for specific SoCs, but for entire families, so
ARCH_NUVOTON is correct.
Yes, I would like to modify it as the following:

config ARCH_NUVOTON
bool "Nuvoton SoC Family"
select PINCTRL
select PINCTRL_MA35D1
select PM
select GPIOLIB
select SOC_BUS
help
This enables support for Nuvoton MA35D1 ARMv8 SoC.

(Currently, we have MA35D1 only in the support list for arm64 SoC.).
You could reword this to "This enables support for Nuvoton ARMv8 SoCs
such as the MA35D1", to prevent this from getting stale, or repeatedly
updated when future SoCs are added.

Another change you can consider is to remove the 'select PINCTRL_MA35D1'
here and instead change the pinctrl Kconfig entry to

config PINCTRL_MA35D1
bool "..."
depends on ARCH_NUVOTON || COMPILE_TEST
default ARCH_NUVOTON

That way you get it default-enabled when ARCH_NUVOTON is
turned on, or disabled in configurations without ARCH_NUVOTON,
but can make a more fine-grained selection for a particular SoC
if you get more than one such driver in the future.

Yes, it looks better.
So, I will modify it as:

config ARCH_NUVOTON
    bool "Nuvoton SoC Family"
    select PINCTRL
    select PM
    select GPIOLIB
    select SOC_BUS
    help
      This enables support for Nuvoton MA35D1 ARMv8 SoC such as MA35D1.

And move PINCTRL_MA35D1 to pinctrl Kconfig when we submit the pictrl driver.

Thanks you.
