Subject: [PATCH 3/8] clk: rockchip: half-divider: convert from round_rate() to determine_rate()
Date: Thu, 28 Aug 2025 20:38:22 -0400 [thread overview]
Message-ID: <20250828-clk-round-rate-v2-v1-3-b97ec8ba6cc4@redhat.com> (raw)
In-Reply-To: <20250828-clk-round-rate-v2-v1-0-b97ec8ba6cc4@redhat.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.
