Subject: [PATCH v2 2/9] drm/mcde/mcde_clk_div: convert from round_rate() to determine_rate()
Date: Mon, 11 Aug 2025 06:56:06 -0400	[thread overview]
Message-ID: <20250811-drm-clk-round-rate-v2-2-4a91ccf239cf@redhat.com> (raw)
In-Reply-To: <20250811-drm-clk-round-rate-v2-0-4a91ccf239cf@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.

Reviewed-by: Linus Walleij <linus.walleij@linaro.org>
