From 9e86b2ad4c11fd52ee8133abce7a29e0b32d29a7 Mon Sep 17 00:00:00 2001 From: Inha Song Date: Mon, 4 May 2015 13:42:13 +0900 Subject: extcon: arizona: Add support for select accessory detect mode when headphone detection This patch add support for select accessory detect mode to HPDETL or HPDETR. Arizona provides a headphone detection circuit on the HPDETL and HPDETR pins to measure the impedance of an external load connected to the headphone. Depending on board design, headphone detect pins can change to HPDETR or HPDETL.
