From 57ef04288abd27a717287a652d324f95cb77c3c6 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 14 Mar 2014 18:16:20 +0100 Subject: gpio: switch drivers to use new callback This switches all GPIO and pin control drivers with irqchips that were using .startup() and .shutdown() callbacks to lock GPIO lines for IRQ usage over to using the .request_resources() and .release_resources() callbacks just introduced into the irqchip vtable.
