If the *internal* clks should be in the same base address, then we
have many external clks as parents, since most of our clks are not
located according to modules which clks serve, but according to clk

Since all clks used for a chip are defined in the same driver file, I
actually can use clk_hw pointer directly, that will cut down the size
of this driver code, and also easier for users to look for parents for
one clk (only need to look at driver file).

But not sure if you aggree this way?

Yes, I noticed that. But I still need to add many .fw_name, that will
not be a small count.
