From 2f46205b4e4c1c2a4b72082f805753eb51fbfab5 Mon Sep 17 00:00:00 2001 From: Sudeep Holla Date: Fri, 27 Nov 2015 17:19:15 +0000 Subject: [PATCH] gpio: pl061: add support for wakeup configuration The PL061 supports interrupts and those can be wakeup interrupts. We need to provide support for configuring those interrupts as wakeup sources. This patch adds irq_set_wake callback for PL061 so that GPIO interrupts can be configured as wakeup.
