From a2ce26f815b16500d390fc46381ec770192a5fbe Mon Sep 17 00:00:00 2001 From: Ville Syrjälä Date: Wed, 11 Jan 2017 14:57:23 +0200 Subject: drm/edid: Introduce drm_hdmi_avi_infoframe_quant_range() Pull the logic to populate the quantization range information in the AVI infoframe into a small helper. We'll be adding a bit more logic to it, and having it in a central place seems like a good idea since it's based on the CEA-861 spec.
