+Subject: [PATCH 3470/4256] drm/amd/powerplay: add smu_smc_read_sensor support
+ for arcturus
+
+the bellow patch refine the sensor read sequence,
+but missed to add arcuturs support. (arcuturs_ppt.c)
+it will cause some sensor is not supported in arcturus.
+
+drm/amd/powerplay: change smu_read_sensor sequence in smu
