Subject: [PATCH 09/30] mmc: sdhci-s3c: remove platform dependencies
Date: Thu, 11 Apr 2013 02:04:51 +0200 [thread overview]
Message-ID: <1365638712-1028578-10-git-send-email-arnd@arndb.de> (raw)
In-Reply-To: <1365638712-1028578-1-git-send-email-arnd@arndb.de>
plat/regs-sdhci.h is not used anywhere but in the sdhci-s3c
driver, so it can become a local file there and all other
inclusions removed.
plat/sdhci.h is used only to define the platform devices,
and with the exception of the platform_data structure not
needed by the driver, so we can split out the platform_data
definition instead and leave the rest to platform code.
