Proper check should be if the hsmmc driver got its platform_data
via devicetree, and not if the devicetree is populated for the

Platform devices for SPI Controller of S3C64XX are defined
and exported for machines to include.
Also, controller setup helper functions are defined for
machine code to set runtime configuration of the controller
and the bus.

Hello,
In subsequent mails, I am going to submit new SPI driver
for the S3C64xx Samsung SoCs.
The driver has been tested with 9pin MMC card slot soldered
to pins of SPI-1 port on the SMDK6410.
Since that is not a standard h/w configuration of SMDK, the patch
to enable SPI-1 controller for MMC_S
We need a way to pass controller specific information to the
SPI device driver. For that purpose a new header is made.
