Subject: [PATCH v2 23/27] usb: gadget: fsl_udc: convert to streaming DMA ops
Date: Thu,  5 Mar 2015 22:50:17 +0100	[thread overview]
Message-ID: <1425592221-23774-27-git-send-email-dev@lynxeye.de> (raw)
In-Reply-To: <1425592221-23774-1-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.
