Subject: [PATCH 1/9] drm/imx/ipuv3/imx-tve: convert from round_rate() to determine_rate()
Date: Thu, 10 Jul 2025 13:43:02 -0400	[thread overview]
Message-ID: <20250710-drm-clk-round-rate-v1-1-601b9ea384c3@redhat.com> (raw)
In-Reply-To: <20250710-drm-clk-round-rate-v1-0-601b9ea384c3@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.
