Cc: Alexander.Deucher-5C7GfCeVMHo, Matt Coffin
[Why]
Before this patch, there was no way to set the gfxclk voltage curve in
the overdrive settings for navi10 through pp_od_clk_voltage
[How]
Add the required implementation to navi10's ppt dpm table editing
implementation, similar to the vega20 implementation and interface.

[Why]
Before this patch, navi10 overdrive settings could not be printed via
pp_od_clk_voltage
[How]
Implement printing for the overdrive settings for the following clocks
in navi10's ppt print_clk_levels implementation:
* SMU_OD_SCLK
* SMU_OD_MCLK
* SMU_OD_VDDC_CURVE

* [PATCH v2 2/3] drm/amdgpu/navi10: implement GFXCLK_CURVE overdrive
@ 2019-11-11 18:22 ` Matt Coffin

Cc: Matt Coffin, Evan.Quan-5C7GfCeVMHo,
amd-gfx-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW
[Why]
Before this patch, there was no way to set the gfxclk voltage curve in
the overdrive settings for navi10 through pp_od_clk_voltage
[How]
Add the required implementation to navi10's ppt dpm table editing
implementation, similar to the vega20 implementation and interface.
