From 3c351f5bb2d04c1f70c72f3f2fd758bbb340877c Mon Sep 17 00:00:00 2001 From: Vijayakumar Date: Mon, 12 Sep 2016 22:36:33 +0530 Subject: gpu: nvgpu: add function to retrieve clk points JIRA DNVGPU-123 Function will copy possible clock points for a given master clock domain to pointer passed. pointer with NULL value and count of zero can be passed to query number of clock points for a given domain so that memory can be allocated and function called again to fill clock points Change-Id: Iec6206f23789980036be99793599e934bd221035 Reviewed-on: http://git-master/r/1218912 (cherry picked from commit 9219697bff1e12deb605325055a02a7b387996e9) Signed-off-by: Vijayakumar Reviewed-on: http://git-master/r/1235055 Reviewed-by: Thomas Fleury GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom --- drivers/gpu/nvgpu/clk/clk_domain.h | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'drivers/gpu/nvgpu/clk/clk_domain.h') diff --git a/drivers/gpu/nvgpu/clk/clk_domain.h b/drivers/gpu/nvgpu/clk/clk_domain.h index 07976a2a..eeb7c256 100644 --- a/drivers/gpu/nvgpu/clk/clk_domain.h +++ b/drivers/gpu/nvgpu/clk/clk_domain.h @@ -33,6 +33,11 @@ typedef u32 clkproglink(struct gk20a *g, struct clk_pmupstate *pclk, typedef u32 clkvfsearch(struct gk20a *g, struct clk_pmupstate *pclk, struct clk_domain *pdomain, u16 *clkmhz, u32 *voltuv, u8 rail); + +typedef u32 clkgetfpoints(struct gk20a *g, struct clk_pmupstate *pclk, + struct clk_domain *pdomain, u32 *pfpointscount, + u16 *pfreqpointsinmhz, u8 rail); + struct clk_domains { struct boardobjgrp_e32 super; u8 n_num_entries; @@ -61,6 +66,7 @@ struct clk_domain { u8 usage; clkproglink *clkdomainclkproglink; clkvfsearch *clkdomainclkvfsearch; + clkgetfpoints *clkdomainclkgetfpoints; }; struct clk_domain_3x { -- cgit v1.2.2
