From d8d09564b830c2040a39039dd1e683c26158f466 Mon Sep 17 00:00:00 2001 From: Richard Fitzgerald Date: Mon, 28 Sep 2015 12:41:42 +0100 Subject: [PATCH] extcon: arizona: Add support for WM8998 and WM1814 This patch adds support for the WM8998 and WM1814 codecs. These use the same IP version as WM5110 but have different clamp control.
