The sink's capabilities, like the DSC caps, depend on the source OUI written to the sink's DPCD registers and so this OUI value should be valid for the whole duration of the detection. An eDP sink will reset this OUI value when the panel power is disabled, so prevent the disabling - happening by default after a 1 sec idle period - for the whole duration of detection. v2: Update the documentation for intel_pps_on().
