Hi Thomas Abraham,
How about separating the variant for Samsung Exynos.
Like dw_mmc-exynos.c
Thanks,
Seungwon Jeon.

Add device nodes for the three instances of spi controllers in Exynos5
platforms and enable instance spi 1 for smdk5250 board.

Add device nodes for the three instances of spi controllers in Exynos4
platforms. Enable instance spi 2 for smdkv310 board and disable all
spi instances for origen board.

Add the platform bits which are required to support SPI controllers.
The OF based partition parsing is also enabled to allow usage of SPI
nor flash on smdk5250 board.

The sclk_spi clock is derived currently from the first level divider
(MMCx_RATIO) which is incorrect. The output of the first level clock
is divided by a second level divider (MMCx_PRE_RATIO), the output of
which is used as the spi bus clock (sclk_spi). Fix the clock hierarchy
issues for the sclk_s
This patch set enables device tree based platform support for the three spi
controllers on Samsung's Exynos4 and Exynos5 SoC's.

With the spi controller hardware configuration moved into the driver data, there
are no more default hardware configuration data that is passed through platform
data. Accordingly, the s3c64xx_spi{0|1|2}_set_platdata functions are adapted to
these changes.

The set_level callback in the controller data, which is used to configure
the slave select line, cannot be supported when migrating the driver to
device tree based discovery. Since all the platforms currently use gpio
as the slave select line, this callback can be removed from the
controller data a
The platform data pointer that is passed to the spi gpio setup functions
is not used. Hence, this paremeter is removed from all the spi gpio setup
functions.

Platform data is used to specify controller hardware specific information
such as the tx/rx fifo level mask and bit offset of rx fifo level. Such
information is not suitable to be supplied from device tree. Instead,
it can be moved into the driver data and removed from platform data.

The macro S3C64XX_SPI_ST_TRLCNTZ is not used and hence it is removed.

Changes since v1:
- Incorporated changes suggested by Mark Brown
- Merged 2nd, 3rd and 5th patch into one single patch.
- Listed the order of gpios in the device tree support documentation.
- Switched to generic property names for chip select gpio line and
number of slave select lines.
