Subject: [PATCH v4 1/4] mmc: atmel-mci: remove useless DMA stuff for non-dt devices
Date: Mon, 1 Dec 2014 15:35:06 +0100 [thread overview]
Message-ID: <1417444509-15501-2-git-send-email-ludovic.desroches@atmel.com> (raw)
In-Reply-To: <1417444509-15501-1-git-send-email-ludovic.desroches@atmel.com>
All devices with a DMA controller are DT compliant and legacy support
has been removed. For those reasons, some DMA stuff is useless.
