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.
Upon further inspection, I found that many arch-specific xlate routines were present only to parse either or both offset and the GPIO_ACTIVE_LOW flag, both of which can be handled at a global level.
This series adds global support for GPIO_ACTIVE_LOW and removes the architecture-specific gpio xlate routine from five drivers.
It also removes the handling of flags in the tegra gpio driver, though a custom xlate is still needed.
