Hi,

This patch is last three patch from https://lkml.org/lkml/2017/1/6/277.
because 1 and 2 patches have already been merged by Krzysztof.

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.

Best Regard,
Jaechul

Changes in v7
- added Chanwoo's reviewed and tested.
- fixed reviews from Dmitry.

Changes in v6:
- changed compatible name from samsaung to cypress.
- updated commit tags.
- removed first two patches from the original patchset.

Changes in v5:
- patch 1: removed a spurious regulator-always-off inherited from
a different patch. Thanks Krzysztof.
- patch 2: fixed a slip on the model, thanks Javier (this patch
confuses me quite a lot, this was all right some patches ago
and re appeared on this one).
- patch 2: removed 'regulator' label and used the original ldo3x
labels. Krzysztof: it looks better indeed.
- added Javier's reviews and Krzysztof's acks on the related
patches.

Changes in v4:
- patch 1 has been rebased on top of 7c294e002641 (arm64: dts:
exynos: Remove unsupported regulator-always-off property from
TM2E)
- patch 2 has been generated with -B50% diff option using git
2.11

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%
