From 664e3e5ac64c8a1999e2d94bc307e5bcd17d3646 Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Wed, 8 Jan 2014 12:40:54 +0200 Subject: gpio / ACPI: register to ACPI events automatically Instead of asking each driver to register to ACPI events we can just call acpi_gpiochip_register_interrupts() for each chip that has an ACPI handle. The function checks chip->to_irq and if it is set to NULL (a GPIO driver that doesn't do interrupts) the function does nothing. We also add the a new header drivers/gpio/gpiolib.h that is used for functions internal to gpiolib and add ACPI GPIO chip registering functions to that header. Once that is done we can remove call to acpi_gpiochip_register_interrupts() from its only user, pinctrl-baytrail.c Signed-off-by: Mika Westerberg Acked-by: Rafael J.
