[PATCH v2 0/6] spi: s3c64xx: add support for device tree

[Thomas Abraham]

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.
- Moved the platform enablement patches for Exynos4 and Exynos5 into a
  different patch series.
- Included Ack from Jaswinder Singh <jaswinder.singh at linaro.org>.

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.
