Subject: [PATCH 1/2] devicetree: sound: add binding for WM8974 codec
Date: Wed, 16 Dec 2015 13:02:54 +0000 [thread overview]
Message-ID: <1450270975-17955-1-git-send-email-mans@mansr.com> (raw)
This adds a binding for the Wolfson WM8974 mono audio codec.
Signed-off-by: Mans Rullgard <mans@mansr.com>
---
The Linux driver for this device currently only supports I2C, but SPI
could easily be added if necessary, and DT bindings are supposed to be
generic.
