dmaengine: move drivers to dma_transfer_direction
fixup usage of dma direction by introducing dma_transfer_direction, this patch moves dma/drivers/* to use new enum Cc: Jassi Brar <jaswinder.singh@linaro.org> Cc: Russell King <rmk+kernel@arm.linux.org.uk> Cc: Viresh Kumar <viresh.kumar@st.com> Cc: Linus Walleij <linus.walleij@linaro.org> Cc: Nicolas Ferre <nicolas.ferre@atmel.com> Cc: Mika Westerberg <mika.westerberg@iki.fi> Cc: H Hartley Sweeten <hartleys@visionengravers.com> Cc: Li Yang <leoli@freescale.com> Cc: Zhang Wei <zw@zh-kernel.org> Cc: Sascha Hauer <s.hauer@pengutronix.de> Cc: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Cc: Shawn Guo <shawn.guo@freescale.com> Cc: Yong Wang <yong.y.wang@intel.com> Cc: Tomoya MORINAGA <tomoya-linux@dsn.lapis-semi.com> Cc: Boojin Kim <boojin.kim@samsung.com> Cc: Barry Song <Baohua.Song@csr.com> Acked-by: Mika Westerberg <mika.westerberg@iki.fi> Acked-by: Linus Walleij <linus.walleij@linaro.org> Acked-by: Viresh Kumar <viresh.kumar@st.com> Acked-by: Nicolas Ferre <nicolas.ferre@atmel.com> Signed-off-by: Vinod Koul <vinod.koul@linux.intel.com>
