From: Swati Sharma swati2.sharma@intel.com
The HDMI2.1 extends HFVSBD (HDMI Forum Vendor Specific Data block) to have fields related to newly defined methods of FRL (Fixed Rate Link) levels, number of lanes supported, DSC Color bit depth, VRR min/max, FVA (Fast Vactive), ALLM etc.
This patch adds the new HFVSDB fields that are required for HDMI2.1.
