From: Jyri Sarha <hidden>
Date: 2014-06-26 19:20:57
Also in:
alsa-devel, linux-omap
Subsystem:
framebuffer layer, omap display subsystem and framebuffer support (dss2), the rest · Maintainers:
Helge Deller, Linus Torvalds
Add audio datamember to hdmi struct and call register and unregister functions form hdmi_audio.c. Register function registers the integrated cpu dai, dummy HDMI codec, and simple-card machine driver for complete HDMI audio support.
