Why exactly this is suitable for DT?
I will use strings instead.
I have doubts why PLL mode is a property of DT. Is this a board-specific
property?
CA-PLL has mode 0 only.
DDRPLL, APLL, EPLL, and VPLL have the same PLL design that supports
integer mode, fractional mode, and spread spctrum mode. The PLL mode
is controlled by clock controller register. I think it's not board-specific.

Drop quotes.
You need here constraints, look for existing examples.
I would like to modify this as:
nuvoton,sys:
description:
Use to unlock and lock some clock controller registers. The lock
control register is in system controller.
$ref: /schemas/types.yaml#/definitions/phandle-array
items:
- items:
- description: phandle to the system controller.
In such case you do not have array. Just make it phandle and drop the items.
Thank you.
So, I will rewrite it as
nuvoton,sys:
description:
Use to unlock and lock some clock controller registers. The lock
control register is in system controller.
$ref: /schemas/types.yaml#/definitions/phandle
Best regards,
Krzysztof
