[U-Boot] [PATCH V2 0/6] Handle GPIO_ACTIVE_LOW in gpio-uclass

[Eric Nelson]

As Peng pointed out in [1], GPIO_ACTIVE_LOW is currently being
parsed by driver-specific xlate routines, and an NXP/mxc-specific
patch ([2]) to do the same on those processors is pending.

This patch series takes a different approach and provides a default
routine for xlate that handles the most common case of GPIO 
device tree node parsing:

	<&gpio1 2 GPIO_ACTIVE_LOW>

The first routine adds the default gpio_xlate_offs_flags() routine,
and the remainder of the patches remove the driver-specific versions
from the intel_broadwell, omap, pic32, rk, and s5p drivers.

V2 of this patch set removes parsing of offset from the gpio_find_and_xlate
routine, and only parses the offset and GPIO_ACTIVE_LOW flag when a
driver-specific xlate is unavailable.

V2 also drops the update to the tegra_gpio driver.

Eric Nelson (6):
  dm: gpio: add a default gpio xlate routine
  gpio: intel_broadwell: remove gpio_xlate routine
  gpio: omap: remove gpio_xlate routine
  gpio: pic32: remove gpio_xlate routine
  gpio: rk: remove gpio_xlate routine
  gpio: exynos(s5p): remove gpio_xlate routine
