Subject: [PATCH 01/10 RESEND] mmc: spi: Move SSP register definitions into separate file
Date: Mon, 23 Jul 2012 22:40:43 +0200 [thread overview]
Message-ID: <1343076052-27312-2-git-send-email-marex@denx.de> (raw)
In-Reply-To: <1343076052-27312-1-git-send-email-marex-ynQEQJNshbs@public.gmane.org>
Move the definitions into separate file so separate SPI driver can be
implemented. The SSP controller in MXS can act both as a MMC host and
as a SPI host.
Based on previous attempt by:

Subject: [PATCH 01/10 RESEND] mmc: spi: Move SSP register definitions into separate file
Date: Mon, 23 Jul 2012 22:40:43 +0200 [thread overview]
Message-ID: <1343076052-27312-2-git-send-email-marex@denx.de> (raw)
In-Reply-To: <1343076052-27312-1-git-send-email-marex@denx.de>
Move the definitions into separate file so separate SPI driver can be
implemented. The SSP controller in MXS can act both as a MMC host and
as a SPI host.
