From c2de745e6d41880275f55de9d4fa88fa6a4c9c33 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1341/2940] drm/amd/powerplay: add interface to parse pptable
(v2)
This patch adds interface to parse pptable for smu.
It's to parse pptable format and fill PPTable_t smc_pptable to smu_table_context
structure. And read the smc_dpm_table from vbios, then fill it into smc_pptable.
v2: add detailed info to describe this function
