From 7e1092b5a264c484001b0cdd1f49bea7884e3366 Mon Sep 17 00:00:00 2001 From: Simon Horman Date: Fri, 24 May 2013 18:47:24 +0900 Subject: gpio-rcar: Add support for IRQ_TYPE_EDGE_BOTH As hardware support for this feature is not universal for all SoCs a flag, has_both_edge_trigger, has been added to the platform data of the driver to allow this feature to be enabled. The motivation for this is to allow use of the gpio-keys driver on the lager board which is based on the r8a7790 SoC. The V2 of this patch has been fully exercised using that driver on that board.
