Work around for a hw bug causing optc underflow if blank data
double buffer disable and remove mpcc.
Checking optc status after otg unlock, after wait mpcc idle
check status again, if optc underflow just happens after wait
mpcc idle, clear underflow status and enable blank data double
buffer.

arr_points[1] and [2] were duplicated. Remove the extra

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.

There are different code to disable front end, it is

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

Update the programming sequence to allow DMCU firmware to be loaded by
PSP. This code detects whether the firmware is loaded and does a check
to verify the expected interface version and checks for correct response
from micro controller.
Added registry key method to allow force loading of firmware from kernel
mode driver for test purposes. This is old method of firmware loading
without PSP.
Moved some init sequences into dc/dmcu.
Changed loading sequence to initialize IRAM after firmware completely
loaded. Firmware will now disable features that use IRAM
until initialized.

For DP active dongles, the dpcd dongle caps are read but not
used to validate mode timing. This addresses this.
In particular, this change fixes light up on the HDMI 4k TV
connected through DP active dongle. Since the 4k TV defaults
to YCbCr420, which the dongle don't support.
This change does not address MST cases, a more generalized
approach must be taken for that.

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).
