[PATCH v3 0/2] gpio: add possibility to search for gpio label name

search for gpio label if gpio name from bankname is not found.

This makes sense on boards with different hardware verions. You
can now search for the gpio label name, and can give the gpio
a unique name. The real gpio pin number is not needed in board
code anymore.

while at it add basic gpio hog test functions in seperate patch.

Travis build:

Changes in v3:
- add comment from Simon Glass
  make this new function configurable through Kconfig

Changes in v2:
- add basic gpio hog test functions
- add comment from Simon Glass
  move code into seperate function dm_gpio_lookup_label()
  add test if dm_gpio_lookup_label() works

Heiko Schocher (2):
  sandbox, test: add test for GPIO_HOG function
  gpio: search for gpio label if gpio is not found through bank name
