--- Comment #5 from René Linder <rene.linder@lihaso.ch> ---
If i go back to where the Powermanagment (smu7_hwmgr.c) where the commit
change:

Since Commit: ab4f06d3adcc5165b13ed2e657050fd1808f319b (agd5f/linux
origin/drm-fixes-4.9
-            iceland_hwmgr_init(hwmgr);
+            topaz_set_asic_special_caps(hwmgr);
+            hwmgr->feature_mask &= ~(PP_SMC_VOLTAGE_CONTROL_MASK |

And the Problem is that it get an empty table back here:
        struct phm_ppt_v1_information *table_info =
                        (struct phm_ppt_v1_information *)hwmgr->pptable;
        struct phm_ppt_v1_clock_voltage_dependency_table *sclk_table = NULL;

        printk("Table info");
        if (table_info == NULL) {
                printk("failed\n");
                return -EINVAL;
        }
        printk("successfull");
