The addition of the compatible string isn't (directly) related with $subject,
this should be done in a separate patch.

...or the patch should just be accurately described as "add support for new variant X, which requires an additional clock Y".

And speaking of which, can anyone clarify how "TCU and TBU core clock" manages to abbreviate to "mem_iface_clk"? I would have naively assumed something like "core" would be most logical.
