From mboxrd@z Thu Jan 1 00:00:00 1970 From: "Patil, Rachna" Subject: [PATCH 4/4] input: TSC: ti_tscadc: Remove definition of End Of Interrupt register Date: Wed, 22 Aug 2012 16:49:40 +0530 Message-ID: <1345634380-29928-1-git-send-email-rachna@ti.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: Received: from arroyo.ext.ti.com ([192.94.94.40]:35484 "EHLO arroyo.ext.ti.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1750759Ab2HVLfo (ORCPT ); Wed, 22 Aug 2012 07:35:44 -0400 Sender: linux-input-owner@vger.kernel.org List-Id: linux-input@vger.kernel.org To: linux-input@vger.kernel.org Cc: Dmitry Torokhov , Dmitry Torokhov , "Patil, Rachna" The touchscreen IP uses level sensitive interrupts rather than edge sensitive interrupts and therefore the is no need to use the EOI register to have the module re-strobe the interrupt line if there pending interrupts exist.
