Unfortunately it reuses a driver_data value of 0 to detect those new bindings, which is already used to denote CHIP_TAHITI ASICs. The driver_data value given to those new bindings was changed in dd0761fd24ea1 ("drm/amdgpu: set CHIP_IP_DISCOVERY as the asic type by default") to CHIP_IP_DISCOVERY (=36), but it seems that the check in amdgpu_pci_probe was forgotten to be changed. Therefore, it still rejects Tahiti GPUs.
