From 028200f75f6d8d0f947d68f41ca10fbfe05f9283 Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Tue, 4 Oct 2016 10:53:32 -0700 Subject: x86/acpi_device: Add support for GPIO output polarity Instead of hard-coding the polarity of the GPIO to active high/low, accept it as a parameter in devicetree. This polarity can then be used while calling into acpi_dp_add_gpio to determine the active low status correctly. BUG=chrome-os-partner:55988 BRANCH=None TEST=Verified that correct polarity is set for reset-gpio on reef.
