* update_clocks --> dcn10_prepare_bandwidth / dcn10_optimize_bandwidth
* --> prepare_bandwidth / optimize_bandwidth. before change dcn hw,
* prepare_bandwidth will be called first to allow enough clock,
* watermark for change, after end of dcn hw change, optimize_bandwidth
* is executed to lower clock to save power for new dcn hw settings.
*
* below is sequence of commit_planes_for_stream:
*
* step 1: prepare_bandwidth - raise clock to have enough bandwidth
* step 2: lock_doublebuffer_enable
* step 3: pipe_control_lock(true) - make dchubp register change will
* not take effect right way
* step 4: apply_ctx_for_surface - program dchubp
* step 5: pipe_control_lock(false) - dchubp register change take effect
* step 6: optimize_bandwidth --> dc_post_update_surfaces_to_stream
* for full_date, optimize clock to save power
*
* at end of step 1, dcn clocks (dprefclk, dispclk, dppclk) may be
* changed for new dchubp configuration. but real dcn hub dchubps are
* still running with old configuration until end of step 5. this need
* clocks settings at step 1 should not less than that before step 1.
* this is checked by two conditions: 1. if (should_set_clock(safe_to_lower
* , new_clocks->dispclk_khz, clk_mgr_base->clks.dispclk_khz) ||
* new_clocks->dispclk_khz == clk_mgr_base->clks.dispclk_khz)
* 2. request_dpp_div = new_clocks->dispclk_khz > new_clocks->dppclk_khz
*
* the second condition is based on new dchubp configuration. dppclk
* for new dchubp may be different from dppclk before step 1.
* for example, before step 1, dchubps are as below:
* pipe 0: recout=(0,40,1920,980) viewport=(0,0,1920,979)
* pipe 1: recout=(0,0,1920,1080) viewport=(0,0,1920,1080)
* for dppclk for pipe0 need dppclk = dispclk
*
* new dchubp pipe split configuration:
* pipe 0: recout=(0,0,960,1080) viewport=(0,0,960,1080)
* pipe 1: recout=(960,0,960,1080) viewport=(960,0,960,1080)
* dppclk only needs dppclk = dispclk /2.
*
* dispclk, dppclk are not lock by otg master lock. they take effect
* after step 1. during this transition, dispclk are the same, but
* dppclk is changed to half of previous clock for old dchubp
* configuration between step 1 and step 6. This may cause p-state
* warning intermittently.
*
* for new_clocks->dispclk_khz == clk_mgr_base->clks.dispclk_khz, we
* need make sure dppclk are not changed to less between step 1 and 6.
* for new_clocks->dispclk_khz > clk_mgr_base->clks.dispclk_khz,
* new display clock is raised, but we do not know ratio of
* new_clocks->dispclk_khz and clk_mgr_base->clks.dispclk_khz,
* new_clocks->dispclk_khz /2 does not guarantee equal or higher than
* old dppclk. we could ignore power saving different between
* dppclk = displck and dppclk = dispclk / 2 between step 1 and step 6.
* as long as safe_to_lower = false, set dpclk = dispclk to simplify
* condition check.
* todo: review this change for other asic.
