+/*
+ * i915 driver supports DSC1.1 from gen11+. To validate DSC, we have
+ * different scenarios
+ * (i) basic modeset (ii) input bpc (iii) formats (iv) fractional bpp
+ * These tests will check for basic DSC support by the connector and
+ * few other gen specific constraints. Fractional bpp got introduced
+ * with DSC1.2 from MTL. By default, tests will get executed on RGB444
+ * output format. However, if sink and platform supports YCBCR420, all the
+ * tests will get executed with this format too.
