Looks like this one was introduced by 7248001, "clk: vt8500: Fix device
clock divisor calculations".

Looks like a copy/paste error where prate was used instead of
parent_rate.

Tony can you test the below patch?

Regards,
Mike

Subject: [PATCH] clk: vt8500: copy-paste mistake in dclk_set_rate

Commit 7248001, "clk: vt8500: Fix device clock divisor calculations"
introduced logic to improve divider selection while changing rates for
the VT8500 dclk.  However a copy-paste error results in using the wrong
variable name in the .set_rate callback.  Fixed by changing *prate to
parent_rate.  The .round_rate function is correct and remains unchanged.
