This patch does following: - Adds a new structure (drm_hdmi_info) in drm_display_info. This structure will be used to save and indicate if sink supports advanced HDMI 2.0 features - Adds another structure drm_scdc within drm_hdmi_info, to reflect scdc support and capabilities in connected HDMI 2.0 sink. - Checks the HF-VSDB block for presence of SCDC, and marks it in scdc structure - If SCDC is present, checks if sink is capable of generating SCDC read request, and marks it in scdc structure. V2: Addressed review comments Thierry: - Fix typos in commit message and make abbreviation consistent across the commit message. - Change structure object name from hdmi_info -> hdmi - Fix typos and abbreviations in description of structure drm_hdmi_info end the description with a full stop. - Create a structure drm_scdc, and keep all information related to SCDC register set (supported, read request supported) etc in it. Ville: - Change rr -> read_request - Call drm_detect_scrambling function drm_parse_hf_vsdb so that all of HF-VSDB parsing can be kept in same function, in incremental patches. V3: Rebase. V4: Rebase. V5: Rebase. V6: Addressed review comments from Ville - Add clock rate calculations for 1/10 and 1/40 ratios - Remove leftovers from old patchset V7: Added R-B from Jose. V8: Rebase. V9: Rebase.
