Where is the compatible (again!)? Test your code - you will see your
binding is a no-op.

I tried to build kernel with CHECK_DTBS=1. And didn't get any message
like 'compatible' is a required property in wifi node. But when I check
the bindings that do required the compatible... So I will add it next time.

Yep, use different clock name and then test. You should see errors,
right? But there are not, because schema is not applied to this node at all.

Look how Apple is doing this.

I have doubts that your code works at all in the first place. If there
is no compatible, how your platform device gets of_node?

In file brcm_hw_ids.h and pcie.c has added Device ID and Vendor ID
for bus to enumerate the device when board bootup, so I didn't add
specific compatible in DTS. And by doing so, it can probe successfully.
