From 12882096517e17b6bc5108b843c85534aefbf6b1 Mon Sep 17 00:00:00 2001 From: Igor Grinberg Date: Sun, 13 Jun 2010 11:31:48 +0300 Subject: [PATCH] [ARM] pxa: add set_type to the pxa3xx ext_wakeup irq chip. pxa3xx cpu needs the irq type setup to be able to wakeup from low power mode on IRQ_WAKEUPx events.
