Subject: clk: imx: pllv2: convert from round_rate() to determine_rate()
X-Git-Tag: io_uring-6.17-20250815~88^2~4^3~7
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=bf7046620975d39ffb084fbad3c0c1f0dec25141;p=linux-block.git

clk: imx: pllv2: 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.
