[U-Boot] [PATCH v5 0/7] Add cros-ec protocol driver and enable it in smdk5250

[Hung-ying Tyan]

This patch series adds the drivers for the cros-ec protocol that is used to
communicate with the Chrome OS Embedded Controller (EC). The series also enables
its use in Google Snow which is based on smdk5250.

The last patch in this series depends on the patch in the MMC series that brings
in exynos5-dt.c:

-----

Changes in v5:
- Change ec-interrupt gpio pin from 174 to 782. This has to be changed again
  after the GPIO pin numbering patches
  (http://patchwork.ozlabs.org/patch/233417) are in.
- Add exynos: tag wherever applicable.
- Add/change dependency description.

Changes in v4:
- Removed unrelated exynos-spi.txt.
- Moved cros-ec-keyb.txt to the cros-ec-keyb patch.
- Removed old code and comment.

Changes in v3:
- Rearranged #include directives in alphabetical order.
- Removed outdated TODO and irrelevant bug reference in comments.

Changes in v2:
- Moved code from smdk5250.c (non-FDT) to exynos5-dt.c (FDT).
- Moved code from smdk5250.h to exynos5250-dt.h.
- Added gpio node to exynos5250.dtsi.
- Fixed warnings of exceeding 80 chars in a line.
- Added commit message.
- Dropped the period from commit subject.
