From 0aed64c1766d354c819a13a57d8673adaf2266eb Mon Sep 17 00:00:00 2001 From: Adam Thomson Date: Tue, 22 Dec 2015 18:27:55 +0000 Subject: [PATCH] ASoC: da7219: Add support for 1.6V micbias level HW can provide 1.6V micbias level as well the existing levels already provided in the driver. This patch adds support for 1.6V to the DT binding.
