From e01f440a689aeb2d0e81c696fe2069f8d01d5d49 Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Thu, 10 Oct 2013 11:01:10 +0300 Subject: gpiolib / ACPI: allow passing GPIOF_ACTIVE_LOW for GpioInt resources The ACPI GpioInt resources contain polarity field that is used to specify whether the interrupt is active high or low. Since gpiolib supports GPIOF_ACTIVE_LOW we can pass this information in the flags field in acpi_find_gpio(), analogous to the DeviceTree version. Signed-off-by: Mika Westerberg Acked-by: Rafael J.
