Subject: [PATCH] MMC: at91_mci: modify cache flush routines
Date: Tue, 11 May 2010 19:09:53 +0200 [thread overview]
Message-ID: <1273597793-28104-1-git-send-email-nicolas.ferre@atmel.com> (raw)
In-Reply-To: <20100511134409.GB27201@n2100.arm.linux.org.uk>
As we were using an internal dma flushing routine, this patch changes to the
DMA API flush_kernel_dcache_page(). Driver is able to compile now.
