Hello

This add button handling for the MC13783 PMIC.

Patch 1 & 2 modify the mc13xxx MFD driver to use the platform data to
resgister the led subdevice and unconditionally register the regulator
subdevice (as suggested by Mark and Uwe).

Patch 3 remove the use of the *_USE_REGULATOR and *_USE_LED macros in
the platform files.

Patch 4 must be applied after patch 1,2,3 to remove the obsolete define.

Patch 5 modify the mc13xxx MFD driver to add a button subdevice and
also adds the mc13783-pwrbutton driver using a misc input device.

The last patch adds the power on button support to the mx31moboard
boards.

v2: first patch modified according to comments by Dmitry Torokhov
v3: Implement review by Uwe
v4: Implement comments by Uwe and Mark
v5: Reorder patchset
v6: Minor corrections

It seems you did not address the comment about possible NULL pdata I
put on v4?

Yes I did in patch 5:
