[PATCH 3 00/18] I2C: OMAP1: OMAP2+: I2C fixes, removal of cpu_is... from driver

[Andy Green]

The following series removes cpu_...() usage completely from the
omap-i2c driver by having decisions about functional implementation
choices in the SoC held in cpu-specific hwmod tables that are
already established, or for OMAP1 where there is no hwmod, set at
OMAP1-specific i2c bus addition time.

Along the way it solves two issues with the existing implementation,
that only 16-bit accesses are documented to be allowed to the I2C
peripheral unit, and that due to a confusion in the existing driver
about whether it is faced with a newer IP version on OMAP3530, currently
it writes to a random non-existent I2C register at times on that
platform.

The patch series is quite extended from the first try thanks to
comments from Benoit Cousson.

This 3rd try is based on 2.6.38-rc8 as requested.
