This patch series adds device tree based discovery support for Samsung's
s3c64xx compatible spi controller. This is mainly tested for Exynos4210
and Exynos5250 with onboard spi nor flash device.

The patch series (6 patches) that add board/platform specific support has
no changes since the v2 version. This series is available at:
