Subject: [PATCH v2 0/4] Let leds use named gpios

The gpio binding docs ask to use named-gpios wherever possible, however 40b73183 probably forgot that. This patch makes the new devm_get_gpiod_from_child use named gpios.

Changed since v1:
  Fix a few typo's
  Fix of_find_gpio to remove hardcoded length of string
  Check both for leds-gpios and if that fails, fall back to standard gpios for the users of devm_get_gpiod_from_child.

Olliver Schinagl (4):
  gpio: use sizeof() instead of hardcoded values
  gpio: add parameter to allow the use named gpios
  leds: Let the binding document example for leds-gpio follow the gpio
    bindings
  leds: no longer use unnamed gpios
