* ARM: ep93xx: move platform_data definitionsArnd Bergmann2012-09-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Platform data for device drivers should be defined in include/linux/platform_data/*.h, not in the architecture and platform specific directories. This moves such data out of the ep93xx include directories Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Acked-by: Nicolas Pitre <nico@linaro.org> Acked-by: Hartley Sweeten <hsweeten@visionengravers.com> Acked-by: Ryan Mallon <rmallon@gmail.com> Acked-by: Vinod Koul <vinod.koul@linux.intel.com> Cc: Grant Likely <grant.likely@secretlab.ca> Cc: Jeff Garzik <jgarzik@pobox.com> Cc: Dan Williams <djbw@fb.com> Cc: Dmitry Torokhov <dmitry.torokhov@gmail.com> Cc: Florian Tobias Schandinat <FlorianSchandinat@gmx.de> Cc: Liam Girdwood <lrg@ti.com> Cc: Jaroslav Kysela <perex@perex.cz> Cc: Takashi Iwai <tiwai@suse.de> Cc: Mika Westerberg <mika.westerberg@iki.fi> Cc: Axel Lin <axel.lin@gmail.com>
* spi/ep93xx: add DMA supportMika Westerberg2011-06-081-0/+10
| | | | | | | | | | | | | | This patch adds DMA support for the EP93xx SPI driver. By default the DMA is not enabled but it can be enabled by setting ep93xx_spi_info.use_dma to true in board configuration file. Note that the SPI driver still uses PIO for small transfers (<= 8 bytes) for performance reasons.
