Bhawanpreet Lakha 5ce868fc47 drm/amd/display: Use seperate dmcub firmware for navy_flounder
[Why]
Currently navy_flounder is using sienna_cichlid_dmcub.bin.

[How]
Create a seperate define so navy_flounder will use its own firmware.

Martin Tsai 3fd20292c2 drm/amd/display: Check lane status again after link training done
[Why]
Some monitors could suffer symbol unlock but cannot send HPD IRQ to
notic source device to handle link loss. This makes monitor stuck in
abnormal status and causes black screen.

[How]
According to the suggestion from scalar vendor, to check lane status
again after link training done. That can improve the comaptibility
from current production monitors.

Alvin Lee bc0cd80783 drm/amd/display: Don't compare dppclk before updating DTO
[Why]
In dcn3_update_clocks there are situations where dppclk is not
lowered (i.e. stays the same), but DTO still needs to be increased
before we program pipe frontend (i.e. in prepare_bandwidth). If we
don't program the new DTO value before we program the pipe,
we will underflow as soon as the pipe lock is released until the
next call to dcn3_update_clocks where the DTO is updated.

[How]
Remove dppclk check before programming new DTO value.

Eryk Brol c6851841fc drm/amd/display: Fix naming of DSC Debugfs entry
[why]
Fix naming and return bits rather than bytes per pixel for
naming consistency. Because registers return Bytes per pixel,
but DSC Config structure is expecting bits per pixel as input.
So when returning the value convert from bytes into bits.

Dave Airlie dc100bc8fa Merge tag 'drm-msm-next-2020-07-30' of https://gitlab.freedesktop.org/drm/msm into drm-next
Take 2 of msm-next pull, this version drops the OPP patch due to [1],
so I'll send the gpu opp/bw scaling patch after the OPP patch lands.
Since I had to force-push I took the opportunity to rebase on
drm-next, and since you already merged in 5.8-rc6 a few fixes from the
last cycle dropped out.

This time around:

* A bunch more a650/a640 (sm8150/sm8250) display and GPU enablement
  and fixes
* Enable dpu dither block for 6bpc panels
* dpu suspend fixes
* dpu fix for cursor on 2nd display
* dsi/mdp5 enablement for sdm630/sdm636/sdm660

I also regenerated the register headers, which accounts for a good
bit of the size this time, because we hadn't re-synced the register
headers since the early days of a6xx bringup.

Rajendra Nayak 32d3e0fecc drm/msm: dsi: Use OPP API to set clk/perf state

requirement on a power domain depending on the clock rates.
Use OPP table from DT to register with OPP framework and use
dev_pm_opp_set_rate() to set the clk/perf state.

dev_pm_opp_set_rate() is designed to be equivalent to clk_set_rate()
for devices without an OPP table, hence the change works fine

Rajendra Nayak b0530eb119 drm/msm/dpu: Use OPP API to set clk/perf state
On some qualcomm platforms DPU needs to express a performance state
requirement on a power domain depending on the clock rates.
Use OPP table from DT to register with OPP framework and use
dev_pm_opp_set_rate() to set the clk/perf state.

Sharat Masetty 1f60d11423 drm: msm: a6xx: send opp instead of a frequency
This patch changes the plumbing to send the devfreq recommended opp rather
than the frequency. Also consolidate and rearrange the code in a6xx to set
the GPU frequency and the icc vote in preparation for the upcoming
changes for GPU->DDR scaling votes.
