Subject: [PATCH 074/114] clk: actions: owl-pll: 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.
