Add clk arbiter support for tu104 setup clk_arb for supporting functions in hal_tu04 TU104 supports GPCCLK and not GPC2CLK Remove multiplication and division by 2 to convert gpcclk to gpc2clk Provide support for following features *Domains: Currently GPCCLK is supported *clk Range: From P0 min to P0 max *Freq Points: Gives the VF curve from PMU *Default: Default value(P0 Max) *Current Pstate: P0 is supported All request for change is freq is validated against P0 value Out of bound values are trimmed to match the Pstate limits Multiple requests are supported and max of that will be set Requests are sent to PMU via change sequencer Bug 200454682 JIRA NVGPU-1653 Change-Id: I36735fa50c7963830ebc569a2ea2a2d7aafcf2ab Signed-off-by: Abdul Salam <absalam@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/1982078 Reviewed-by: Vijayakumar Subbu <vsubbu@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
