[PATCH v2 0/7] Add device tree support for imx spi driver

[Shawn Guo <shawn.guo-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>]

The patch set makes some cleanups on imx spi driver to get it ready
for adding device tree probe and then add the support.

Changes since v1:
 * Split the big patch into small ones per Sascha's comment
 * Drop the patch cleaning mxc/mach/gpio.h from the series.  Will
   post it separately later.
 * Drop dt helper patches, as they are on Grant's tree

Shawn Guo (7):
      spi/imx: do not make copy of spi_imx_devtype_data
      spi/imx: use mx21 to name SPI_IMX_VER_0_0 function and macro
      spi/imx: do not use spi_imx2_3 to name SPI_IMX_VER_2_3 function and macro
      spi/imx: merge type SPI_IMX_VER_0_7 into SPI_IMX_VER_0_4
      spi/imx: use soc name in spi device type naming scheme
      spi/imx: copy gpio number passed by platform data into driver private data
      spi/imx: add device tree probe support
