[PATCH 0/4] OMAP 3 and 4 i2c fixes

The following series fixes two issues with OMAP 3 and 4 i2c support.
First, hwmod tables don't have the i2c units marked up as being
for 16-bit access only, which is mandatory.
Second, the i2c peripheral unit init code is confused about using
cpu_is...() and probed peripheral unit version, leading to OMAP3
i2c code doing the wrong thing and accessing nonexistant registers.
Andy Green (4):
OMAP3 and 4 I2C use cpu type consistently for new register availability
OMAP3 and 4 i2c mark extended reg enums as extended only
OMAP3 I2C document why cpu type and not peripheral unit ID used to probe
OMAP3 and 4 hwmod I2C units only allow 16 bit access
