From mboxrd@z Thu Jan 1 00:00:00 1970 From: Kevin Hilman Subject: [PATCH 3/3] ARM: DTS: TWL4030: fix mux and wakeup for SYS_NIRQ line Date: Fri, 31 May 2013 15:45:57 -0700 Message-ID: <1370040357-25794-4-git-send-email-khilman@linaro.org> References: <1370040357-25794-1-git-send-email-khilman@linaro.org> Return-path: Received: from mail-pd0-f170.google.com ([209.85.192.170]:50034 "EHLO mail-pd0-f170.google.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1756836Ab3EaWqI (ORCPT ); Fri, 31 May 2013 18:46:08 -0400 Received: by mail-pd0-f170.google.com with SMTP id x10so2920220pdj.1 for ; Fri, 31 May 2013 15:46:08 -0700 (PDT) In-Reply-To: <1370040357-25794-1-git-send-email-khilman@linaro.org> Sender: linux-omap-owner@vger.kernel.org List-Id: linux-omap@vger.kernel.org To: Benoit Cousson , linux-omap@vger.kernel.org Cc: linux-arm-kernel@lists.infradead.org On most OMAP3 platforms, the twl4030 IRQ line is connected to the SYS_NIRQ line on OMAP. Therefore, configure the defaults for the SYS_NIRQ pin in the twl4030 DTS file. Boards that hook up the twl4030 differently can easily override this in their board-specific DTS file. This allows RTC wake from off-mode to work again on OMAP3-based platforms with twl4030. Tested on 3530/Beagle, 3730/Beagle-xM, 3530/Overo, 3730/Overo-STORM.
