[PATCH 004/114] clk: at91: audio-pll: convert from round_rate() to determine_rate()

[Brian Masney via B4 Relay <devnull+bmasney.redhat.com@xxxxxxxxxx>]

From: Brian Masney <bmasney@xxxxxxxxxx>

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.
