Subject: [PATCH 1/2] atmel-mci: Integrate AT91 specific definition in header file
Date: Fri, 12 Jun 2009 17:58:29 +0200	[thread overview]
Message-ID: <1244822310-11562-1-git-send-email-nicolas.ferre@atmel.com> (raw)
Message-ID: <81b92e58966b864e4a26004204f43d242d9cc8aa.1244821292.git.nicolas.ferre@atmel.com> (raw)

The MCI IP is shared among AVR32 and AT91 SOCs.
AT91 has specific bit definitions in the user interface of MCI SD/MMC IP.

Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com>

Thanks to Rob Emanuele who has begun this unification work. I take the hand on
this header file work as I have some bits to integrate for MCI2 support.
