From 1ddde15e99a2033c8e21a9ab34a72f166c4bd385 Mon Sep 17 00:00:00 2001 From: Brian Masney Date: Mon, 11 Aug 2025 11:17:57 -0400 Subject: [PATCH] clk: at91: h32mx: 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.
