[PATCH RFC v2 REPOST 6/8] drm/tilcdc: Add I2C HDMI audio config for tda998x
From: Jyri Sarha <hidden>
Date: 2013-12-20 10:41:44

alsa-devel, dri-devel, linux-devicetree, linux-omap
Subsystem:
drm drivers, drm drivers and misc gpu patches, drm drivers for ti lcdc, the rest · Maintainers:
David Airlie, Simona Vetter, Maarten Lankhorst, Maxime Ripard, Thomas Zimmermann, Jyri Sarha, Tomi Valkeinen, Linus Torvalds
The configuration is needed for HDMI audio. The "swap" and "mirr" parameters have to be correctly set in the configuration in order to have proper colors in the HDMI picture.
