I have parsed the board files for a pattern.
There are some, but I have my doubts as well:
We have eight platform data members in twl4030_platform_data for child 
devices.
USB, and audio/codec configuration might worth to move out (since most of the 
board does not have fine tuned parameters for codec).

The majority of the code related to pmic is coming from regulator setups, I 
can see similarities, but there are differences here and there, which makes 
the common configuration mostly useless (different peripherals, boot loader 
diffs, etc).

Having said that, I try to create a wrapper for omap_pmic_init, which can 
replace the current omap2/3/4_pmic_init, with that we can use common config 
for USB, audio, and some selected few regulators initially.
Later other parts might be possible to consolidate as well.
I'm going to call this new wrapper for now omap2/3/4_pmic_config.

Is this a good way to approach this issue?
