  This adds a schema for the STMPE GPIO that while it is used a
lot in the kernel tree is anyway missing its bindings.

Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

ChangeLog v1->v2:
- New patch split off from the MFD patch.

All you need for hog nodes is:

"^.+-hog(-[0-9]+)?$":
  type: object
  required:
    - gpio-hog

The presence of 'gpio-hog' causes the hog schema to be applied.
