Does this patch help? Please include all the radeon related output. The pointers are fine. The problem seems to be that the panel returns all 0s for the dpcd unless the panel is in D0 state.
When I tried applying this patch, my laptop freeze (network gets unresponsive). It worked only when *radeon_dp_set_rx_power_state(&radeon_connector->base, DP_SET_POWER_D0);* was commented out in radeon_dp_getdpcd().
Patches from #101 & #102 also didnt help.
