Device tree support for TWL regulators
v2 cover Device tree support for TWL regulators
This series adds DT support for TWL regulator driver and passes regulator data for two OMAP4 boards (OMAP4 panda and OMAP4 sdp) from device tree.
Patches are based on for-next of the regulator tree[1] with omap i2c/twl DT adaptation patches[2] from Benoit pulled in and are available here:git://gitorious.org/omap-pm/linux.git for-dt/regulator-twl

PATCH v2 1/3 regulator: twl: adapt twl-regulator driver to dt
Modify the twl regulator driver to extract the regulator_init_data from device tree when passed, instead of getting it through platform_data structures (on non-DT builds)
Also add documentation for TWL regulator specific bindings.
