From 48f15e94f5a30bf335c3c972d592bc9212aca9ff Mon Sep 17 00:00:00 2001 From: Bjorn Andersson Date: Mon, 31 Mar 2014 14:49:54 -0700 Subject: [PATCH] pinctrl: msm: Correct interrupt code for TLMM v2 Acking interrupts are done differently between on v2 and v3, so add an extra attribute to the pingroup struct to let the platform definitions control this. Also make sure to start dual edge detection by detecting the rising edge.
