Subject: [PATCH 03/10] mmc: spi: Add necessary bits into mxs-spi.h
Date: Fri,  3 Aug 2012 17:26:08 +0200	[thread overview]
Message-ID: <1344007575-11448-4-git-send-email-marex@denx.de> (raw)
In-Reply-To: <1344007575-11448-1-git-send-email-marex@denx.de>

Add missing register bits and registers into mxs-spi.h .
These will be used by the SPI driver.

Based on previous attempt by:
