Subject: mmc: mmci: implement pre_req() and post_req()
X-Git-Tag: v3.1-rc1~321^2~32
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=58c7ccbf9109abcc6b7ed2f76c21ebee244d31a8;p=pandora-kernel.git

mmc: mmci: implement pre_req() and post_req()

pre_req() runs dma_map_sg() and prepares the dma descriptor for the next
mmc data transfer. post_req() runs dma_unmap_sg.  If not calling pre_req()
before mmci_request(), mmci_request() will prepare the cache and dma just
like it did it before.  It is optional to use pre_req() and post_req()
for mmci.
