From mboxrd@z Thu Jan 1 00:00:00 1970 From: "Patil, Rachna" Subject: [PATCH RESEND 4/8] input: TSC: ti_tscadc: Remove definition of End Of Interrupt register Date: Tue, 16 Oct 2012 12:55:41 +0530 Message-ID: <1350372345-27108-5-git-send-email-rachna@ti.com> References: <1350372345-27108-1-git-send-email-rachna@ti.com> Mime-Version: 1.0 Content-Type: text/plain Return-path: In-Reply-To: <1350372345-27108-1-git-send-email-rachna@ti.com> Sender: linux-kernel-owner@vger.kernel.org To: linux-kernel@vger.kernel.org, linux-input@vger.kernel.org, linux-iio@vger.kernel.org Cc: Samuel Ortiz , Dmitry Torokhov , Dmitry Torokhov , Jonathan Cameron , "Patil, Rachna" List-Id: linux-input@vger.kernel.org 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.
