Subject: [PATCH 046/114] clk: sifive: sifive-prci: convert from
round_rate() to determine_rate()
From: Brian Masney <bmasney@...hat.com>
The round_rate() clk ops is deprecated, so migrate this driver from
round_rate() to determine_rate() using the Coccinelle semantic patch
on the cover letter of this series.
Note that the changes to the three header files were done by hand.
