During phy compliance auto test mode source need to read requested test pattern from sink through DPCD. After processing the request source need to set the pattern. So set/get method added in drm layer as it is DP protocol. v2: As per review feedback from Manasi on RFC version, - added dp revision as function argument in set_phy_pattern api. - used int for link_rate and u8 for lane_count to align with existing code. v3: As per review feedback from Harry, - used sizeof() instead of magic number. - corrected kernel-doc for drm_dp_phy_test_params structure.
