Subject: [PATCH v2 1/2] i2c: s3c2410: move mach/regs-iic.h into i2c-s3c2410 device driver
Date: Thu, 21 Mar 2013 15:09:25 +0100	[thread overview]
Message-ID: <201303211509.25607.heiko@sntech.de> (raw)

The register definitions are only used in the driver itself.
This also removes the last dependency on plat/ includes from the
i2c driver.
