Subject: [PATCH 03/12] mci: sdhci: Use SDHCI_MAX_DIV_SPEC_200 define
Date: Mon,  7 Jun 2021 12:44:02 +0200	[thread overview]
Message-ID: <20210607104411.23071-4-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20210607104411.23071-1-s.hauer@pengutronix.de>

Linux uses SDHCI_MAX_DIV_SPEC_200 for what we have
SDHCI_SPEC_200_MAX_CLK_DIVIDER. Also we have SDHCI_MAX_DIV_SPEC_300
defined in the arasan driver. Use the Linux defines and add them
both to the header file.
