Subject: [PATCH v3 06/14] mci: core: save the set clock as actual_clock
Date: Fri, 15 Mar 2024 15:00:47 +0100	[thread overview]
Message-ID: <20240315-v2024-02-0-topic-arasan-hs200-support-v3-6-df268c2f4907@pengutronix.de> (raw)
In-Reply-To: <20240315-v2024-02-0-topic-arasan-hs200-support-v3-0-df268c2f4907@pengutronix.de>

Linux mmc_host saves the actual_clock set on the HC. Do the same to use
it later.
