[PATCH 0/4] gpiolib debug and led trigger fixes

[Sebastian Hesselbarth]

This small set of patches first fixes led triggers, where the led
should be disabled, before installing a trigger function. Otherwise,
the led may stay enabled from previous bootloaders messing with it.

The second part of the patches impoves gpiolib command verbosity by
first adding an (optional) callback to get_direction of a gpiochip
pin. Based on that new callback, it adds some more printf information
to reflect gpiochip/gpio pin relation and also print current pin
direction and value, if the corresponding callbacks are available.
Finally, the get_direction callback is added to the Synopsys DW gpio
driver.

Sebastian Hesselbarth (4):
  led: trigger: disable LEDs with trigger before installing it
  gpiolib: add get_direction callback
  gpiolib: make gpiolib command more verbose
  gpio: dw: add get_direction callback
