Subject: [PATCH 20/24] usb: gadget: fsl_udc: convert to streaming DMA ops
Date: Sun,  1 Mar 2015 14:17:18 +0100	[thread overview]
Message-ID: <1425215842-6982-21-git-send-email-dev@lynxeye.de> (raw)
In-Reply-To: <1425215842-6982-1-git-send-email-dev@lynxeye.de>

Move to the common streaming DMA ops in order to get rid of
the direct usage of the ARM MMU functions for the cache
maintenance.
