[PATCH 0/3] Device tree support for TWL regulators

[PATCH 0/3] Device tree support for TWL regulators

[Rajendra Nayak]

Hi,

This series adapts TWL regulator driver to work with device
tree and passes regulator data for two OMAP4 boards (OMAP4
panda and OMAP4 sdp) from device tree.

The series has a few dependencies
-1- base regulator dt support series posted here
http://marc.info/?l=linux-omap&m=131970236516788&w=2
-2- All base omap3/4 DT support patches lined up
for 3.2 merge here
git://github.com/tmlind/linux.git dt
-3- patches for i2c/twl support posted here
http://marc.info/?l=linux-omap&m=131705583821757&w=2

All the dependent patches and the ones posted as part
of this series are pulled in one branch can be found here
git://gitorious.org/omap-pm/linux.git for-dt/regulator-i2c-twl

regards,
Rajendra

[PATCH 1/3] regulator: twl: adapt twl-regulator driver to dt

[Rajendra Nayak]

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)

[PATCH 2/3] omap4: sdp: Pass regulator data from dt

[Rajendra Nayak]

Pass adjustable regulator information for omap4sdp from device tree so the
regulator driver can then use the regulator helper
routine to extract and use them during the driver probe().

Also add documentation for TWL regulator specific bindings.
