There are two. While the TRM states:

"""
There are two MIPICDPHY_GRF modules in RK3588.They have different base 
address.
"""

(ignore the typo :) )

it states the same for the bigcore grf but we have two bindings for them 
in there... So not sure what to go for here? Similarly, pipe-grf has 
three instances but we define only one binding...

So who knows :)

That being said,
