Same here

All other devices have name ma35d1. Is this a different SoC?

Drop description, it's obvious.

Drop clock-names, you do not bring any new information.

Describe what is it for.

Keep the same order as in properties.

Where do you use it?

Okay, I will make the correction and use the correct name.

The SoC is the same as ma35d1. I will modify ma35 to ma35d1.

Originally, I intended to create a series of shared drivers.

Because this driver has some status bits located in the sys, it is 
necessary to reference the sys link.

Describe it in the binding - what usb2 phy needs to do in sysmgmt node.
