From c6e86db2bec56e05c7ad1524ed2273a4cc8e8868 Mon Sep 17 00:00:00 2001 From: "Patil, Rachna" Date: Tue, 16 Oct 2012 12:55:41 +0530 Subject: input: TSC: ti_tscadc: Remove definition of End Of Interrupt register 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.
