> Subject: [PATCH v2 0/3] navi10: Implement overdrive pp_od_clk_voltage
> 
> [Why]
> Before this patchset, navi10 users could not utilize the overdrive functionality.
> This prevented them from overclocking, overvolting, or undervolting their cards.
> 
> [How]
> Similar to the vega20 implementation, add the pp_od_clk_voltage interface to
> the navi10 powerplay table.
> 
> [Possible Alternatives]
> This could also be done more generically in smu_v11_0 code, but would require
> more significant changes to the vega20 code, and feature-gating based on chip
> capabilities in the smu to disable overdrive for arcterus.
> I chose this path so as not to completely refactor the vega20 side of things, and
> introduce SMU code which would not play nicely with new ASICs.
> 
> v2: rebase off latest code, and remove an incorrect bounds check
