Subject: [PATCH V2] drm/amd/smu: Increace dpm level count only for smu v13.0.2
[AMD Official Use Only - General]
From: Likun Gao <Likun.Gao@xxxxxxx>
Only V13.0.2 on SMU v13 will get 0 based max level from fw and increment by one, other ASIC will not need for this.
V2: replace the asic_type check with ip versioning check.
