From 72a1179ed41e0fc6bd5eb58e02e8d230eba10e24 Mon Sep 17 00:00:00 2001 From: Samu Onkalo Date: Mon, 2 Aug 2010 14:21:40 +0300 Subject: omap: dma: Support for prefetch in destination synchronizedtransfer Omap DMA controller can prefetch data in advance in case of destination synchronized data transfer. This may increase performance when target HW block doesn't have fifo. Data is waiting for transfer request in DMA fifo instead of read from memory.
