This patch series adds SPI bus support and devices for the MityDSP-L138,
MityARM-1808, da850 evm, and da830 evm platforms. This patch series is
against the staging tree at [1] as per Sekhar's instructions.
This series has been tested on the MityDSP-L138 platform.
[1] http://arago-project.org/git/projects/?p=linux-davinci.git;a=shortlog;h=refs/heads/next-for-kevin
---
changes since v3:
-- first 5 patches of series are incorporated in [1] and not included
in this submission
-- refactored common spi registration code into da8xx_register_spi
routine, reducing effective lines of code for multiple platform
support.

I queued these patches for Kevin to pick-up for 2.6.39
Thanks for your efforts on this.
