Subject: clk: imx: pll14xx: convert from round_rate() to determine_rate()
X-Git-Tag: io_uring-6.17-20250815~88^2~4^3~8
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=c677a5a0eeb1accb437e26279b288423cda09592;p=linux-block.git

clk: imx: pll14xx: convert from round_rate() to determine_rate()

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.
