From 9c2ba270eaa227c999af451e1c2c9bf0d24aa8e5 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 25 Feb 2013 23:42:31 +0000 Subject: extcon: arizona: Simplify HPDET based identification Rather than measuring both HP channels we can simply directly measure the microphone impedance and then rely on MICDET for final confirmation of the presence of a suitable microphone. This improves the overall performance of the identification process.
