Subject: [PATCH 09/12] mci: sdhci: Use Linux defines for SDHCI_CLOCK_CONTROL register
Date: Mon,  7 Jun 2021 12:44:08 +0200	[thread overview]
Message-ID: <20210607104411.23071-10-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20210607104411.23071-1-s.hauer@pengutronix.de>

Convert another register to use the Linux defines.
