The EDID is derived from test_edid_hdmi_4k_rgb_yuv420_dc_max_340mhz with the following changes: - Upgraded the first DTD from 3840x2160@30 (297 MHz) to 3840x2160@60 (594 MHz). The H/V totals (4400x2250) and porches already match the HDMI 2.0 4K@60Hz standard timing, so only the pixel clock had to be bumped. - Widened Display Range Limits descriptor to cover the new timing, i.e. 24-140 kHz H, max dotclock 600 MHz. - Updated CTA-861 Video Data Block to advertise VIC 97 (4K@60Hz) instead of VIC 95 (4k30). - Bumped HF-VSDB Max TMDS Character Rate to 600 MHz, keeping SCDC_Present set so that the sink advertises scrambling support. - Cleared HDMI VSDB Max TMDS clock byte, as required by HDMI 2.0 when the HF-VSDB declares a Max TMDS Character Rate above 340 MHz. - Provided a Video Capability Data Block advertising selectable RGB and YCC quantization range plus underscan for IT/CE formats; also set the 'IT Video Formats Underscanned' bit in the CTA-861 extension header to match. - Aligned base block image size with the DTD (160x90 cm) and replaced the bogus 'Week of Manufacture = 0xff' with the Model Year code, both fixing inherited EDID conformity warnings. - Dropped the empty YCbCr 4:2:0 Video Data Block inherited from the parent EDID, which is flagged as a failure by edid-decode v1.33.0 Signed-off-by: Cristian Ciocaltea ---
