How about this:
Regarding Dirk's and Heiko's comment:
A) How about board/omap3/common/power.c to drivers/power/twl4030.c
On patch [PATCH 2/4] I2C Add initial support for TWL4030:
B) introduce a new header in include/twl4030.h from Tom's patch
Remove drivers/i2c/twl4030_i2c.c from the patch instead add:
#define TWLL4030_READ_U8(MODULE, VAL,REG)\
i2c_read((MODULE), (REG), 1, (VAL), 1)
#define TWLL4030_WRITE_U8(MODULE, VAL,REG)\
i2c_read((MODULE), (REG), 1, (VAL), 1)
to include/twl4030.h in the patch.
C) on [PATCH 3/4] ZOOM2 Add power reset button
The change should go to corresponding board file -> for zoom1 or zoom2.

Nishanth Menon
