From 06a09124b5ec65f81df66c56695d9a9ae04a0114 Mon Sep 17 00:00:00 2001 From: Michael Hennerich Date: Tue, 9 Mar 2010 20:38:45 -0800 Subject: Input: ads7846 - add support for AD7843 parts The AD7873 is almost identical to the ADS7846; the only difference is related to the Power Management bits PD0 and PD1. This results in a slightly different PENIRQ enable behavior. For the AD7873, VREF should be turned off during differential measurements. So, add the AD7873/43 to the list of driver supported devices, and prevent VREF usage during differential/ratiometric conversion modes.
