Subject: [PATCH v3 0/5] Add touch key driver support for TM2

Hi,

This patchset adds support for the tm2 touchkey device.

The driver has been ported from Tizen Kernel, originally written
by Beomho. I ported it to the latest mainline Kernel.

This patch need to apply after this one:
https://lkml.org/lkml/2016/12/29/319

Changes in v3:
 - Changed the commit ordering, the tm2-touchkey related patches
   are the last 3.
 - Added Chanwoo's patch which fixes the wrong voltage of ldo23
   and ldo25.
 - Andi (patch 3) moves the ldo31 and ldo38 in the tm2 and tm2e
   files as they have different values.

Changes in v2:
 - fixed reviews from Javier, Dmitry
 - refactored power enable/disable functions.
 - reordered signed-offs in patch 2, while patch 4 is left as it
   was as Andi copy pasted the node to the new tm2.dts file
 - added Jarvier's (patch 1,2,4) and Krzysztof's (patch 4) reviews
   and Rob's Ack
 - patch 3 diff has been generated with -B50%
