97110c98a0 drm/amd/display: Remove extra arr_points element
arr_points[1] and [2] were duplicated. Remove the extra
one. If we ever need more points we can add them but the
current state of affairs is confusing.

631aaa0af4 drm/amd/display: send display_count msg so SMU can enter S0i2
SMU can future lower voltages in long idle case when all display is off.

If all display output is turned off via DPMS, send display_count = 0
after all output are turned off.

otherwise send display_count msg before turning on display to make sure
SMU exit S0i2 state.  before is not neccessary as we are out of S0i2
when driver execute code, but send message before anyways for correctness.

fa2123dbcc drm/amd/display: Multi display synchronization logic
This feature synchronizes multiple displays with various timings
to a display with the highest refresh rate
it is enabled if edid caps flag multi_display_sync is set to one

There are limitations on refresh rates allowed
that can be synchronized. That would
prevent from underflow and other potential
corruptions.

Multi display synchronization is using the
same functions as timing_sync in order to minimize
redunduncy and decision to disable synchronization is
based on trigger parametre set in DM

Feature is developed for DCN1 and DCE11

2f2c3b36fc drm/amd/display: fix memory leaks on error exit return
Currently in the case where some of the allocations fail for dce110_tgv,
dce110_xfmv, dce110_miv or dce110_oppv then the exit return path ends
up leaking allocated objects. Fix this by kfree'ing them before returning.
Also re-work the comparison of the null pointers to use the !ptr idiom.

8740196935 drm/amd/display: Move power control from link encoder to hwsequencer
A recent commit moved the backlight control code along with the register
defines, but did not move the power control code. This along with
remnant fields in the dce110_link_enc_registers struct made it so that
the code still compiled, but any attempts to access the
LVTMA_PWRSEQ_STATE register led to reading from an address of 0. This
patch corrects that.

Also, rename blacklight_control to edp_backlight_control (Typo fix).
