From 7e567624dc5a44276d9df253f5ca829d911b4e93 Mon Sep 17 00:00:00 2001 From: Jyri Sarha Date: Tue, 9 Aug 2016 22:00:05 +0300 Subject: drm/i2c: tda998x: Register ASoC hdmi-codec and add audio DT binding Register ASoC HDMI codec for audio functionality and adds device tree binding for audio configuration. With the registered HDMI codec the tda998x node can be used like a regular codec node in ASoC card configurations. HDMI audio info-frame and audio stream header is generated by the ASoC HDMI codec. The codec also applies constraints for available sample-rates based on Edid Like Data from the display. The device tree binding document has been updated [1]. Part of this patch has been inspired by Jean Francoise's "drm/i2c: tda998x: Add support of a DT graph of ports"-patch [2]. There may still be some identical lines left from the original patch and some of the ideas have come from there.
