From 3d345b5f7b2f613b6965fc3fc68de9f439752ffe Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Tue, 19 Sep 2017 19:59:04 -0300 Subject: ASoC: tfa9879: Add device tree bindings MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Even though the tfa9879 driver can probe via device tree trough the I2C core code, it is preferable to have explicit device tree bindings instead [1], so add this support.
