From mboxrd@z Thu Jan 1 00:00:00 1970 From: Maxime Ripard Subject: [PATCH v2] input: tca8418: Use the interrupt trigger from the device tree Date: Mon, 14 Nov 2016 09:39:11 +0100 Message-ID: <20161114083911.2423-1-maxime.ripard@free-electrons.com> Return-path: Received: from mail.free-electrons.com ([62.4.15.54]:34863 "EHLO mail.free-electrons.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1752188AbcKNIjR (ORCPT ); Mon, 14 Nov 2016 03:39:17 -0500 Sender: linux-input-owner@vger.kernel.org List-Id: linux-input@vger.kernel.org To: Dmitry Torokhov Cc: linux-input@vger.kernel.org, linux-kernel@vger.kernel.org, Maxime Ripard The TCA8418 might be used using different interrupt triggers on various boards. This is not working so far because the current code forces a falling edge trigger. The device tree already provides a trigger type, so let's use whatever it sets up, and since we can be loaded without DT, keep the old behaviour for the non-DT case.
