From bb2f45927f8e0d1fc0633f65cc1f17a40c80bf24 Mon Sep 17 00:00:00 2001 From: Apelete Seketeli Date: Mon, 21 Jul 2014 06:37:45 +0200 Subject: [PATCH] mmc: jz4740: prepare next dma transfer in parallel with current transfer Make use of the MMC asynchronous request capability to prepare the next DMA transfer request in parallel with the current transfer. This is done by adding pre-request and post-request callbacks that are used by the MMC framework during an active data transfer. It should help reduce the impact of DMA preparation overhead on the SD card performance. Signed-off-by: Apelete Seketeli Signed-off-by: Ulf Hansson --- Reading git-format-patch failed
