Subject: [PATCH] Add support for Sony SxS cards
Date: Mon,  7 Jul 2014 10:53:13 +0100	[thread overview]
Message-ID: <1404726794-8964-1-git-send-email-kieran@kunhya.com> (raw)

This patch adds a reverse-engineered read-only driver for Sony SxS cards.
SxS cards are an Expresscard based memory card used in professional cameras.

I've not managed to get block device DMA working for some reason and currently
this driver uses a memcpy. I may well be using the block device DMA API incorrectly.

The block device DMA code can be found here:
https://github.com/kierank/sxs-linux/blob/dma/sxs.c

Any comments on the DMA code would also be appreciated.
