From f2e2026c98b74028b55901711c5df98e6d2ad8c6 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 2 Dec 2011 15:55:52 +0000 Subject: [PATCH] ASoC: Add WM8958 based headset detection on Littlemill The board supports CODECs that won't work with this but the CODEC driver will check to see if it's running on the right chip for us.
