From a3047065b91b159276dfcb41c6477fd27916c5d0 Mon Sep 17 00:00:00 2001
From: Matt Coffin <mcoffin13@gmail.com>
Date: Fri, 8 Nov 2019 14:28:06 -0700
Subject: [PATCH 4416/4736] drm/amdgpu/navi10: implement sclk/mclk OD via
pp_od_clk_voltage
[Why]
Before this patch, there was no way to use pp_od_clk_voltage on navi
[How]
Similar to the vega20 implementation, but using the common smc_v11_0
headers, implemented the pp_od_clk_voltage API for navi10's pptable
implementation
