Subject[PATCH AUTOSEL 5.4 126/350] drm/amd/display: fix header for RN clk mgr
From: joseph gravenor <>

[ Upstream commit cd83fa1ea9b9431cf1d57ac4179a11bc4393a5b6 ]

Should always MP0_BASE for any register definition from MP per-IP header files.
I belive the reason the linux version of MP1_BASE works is The 0th element of the 0th table
of that is identical to the corrisponding value of MP0_BASE in the renoir offset header file.
The reason we should only use MP0_BASE is There is only one set of per-IP headers MP
that includes all register definitions related to SMU IP block. This IP includes MP0, MP1, MP2
and an ecryption engine that can be used only by MP0. As a result all register definitions from
MP file should be based only on MP0_BASE data.

Change MP1_BASE to MP0_BASE
