+Subject: [PATCH 1342/2940] drm/amd/powerplay: add interface to populate smc
+ pptable (v2)
+
+This patch adds interface to populate smc pptable for smu.
+It's to set initialized values (get from vbios) to dpm tables context such as
+gfxclk, memclk, dcefclk, and etc. And enable the DPM feature for each type of
+clks.
+
+v2: add detailed info to describe this function
+
