[why]
handler is supposedly passed in as a function pointer;
however, the entire struct amdgpu_dm_irq_handler_data
gets from the list is used to check match.
[how]
use the interrupt_handler within amdgpu_dm_irq_handler_data
for checking match.

[WHY]
HUBP blanking sequence on DCN30 requires us to check if HUBP is in blank
and also toggle HUBP_DISABLE, which should instead be called
HUBP_SOFT_RESET for what it does in HW.

[why]
Some MST display may not report the internal panel to DEVICE_COUNT,
that makes the check condition always failed.
[how]
To update this condition with the reported device count + 1
(because the immediate repeater's internal panel is possibly
not included in DEVICE_COUNT)

Using abm_parameters structure to get these values from driver.

From: Yongqiang Sun <yongqiang.sun@amd.com>
[Why]
there is some garbage showing up during reboot test.
Reason:
SMU might handle display driver msg defered and driver will send
next msg to SMU after 10ms timeout, once SMU FW handle previous msg,
parameters are changed to next one, which result in a wrong value be programmed.
[How]
Extend timeout to 2s so SMU will have enough time to handle driver msg.

[WHY]
Virtual signals were previously counted as a workaround to S0i2 hang
which is fixed on Renoir. This blocks S0i3 diags testing.

[WHY]
DSC should only be acquired per OPP. Therefore, DSC should only
be acquired for the top_pipe when ODM is enabled.
Not doing this check may lead to acquiring more DSC's than needed
when doing MPO + ODM Combine.
[HOW]
Only acquire DSC if pipe is top_pipe.

From: Jake Wang <haonan.wang2@amd.com>
[Why]
We defer clock updates to after pipes have been programmed. In
some instances we use DPPCLK that have been previously set to be
"unused". This results in a brief window of time where underflow
could occur.
[How]
During prepare bandwidth allow rn_update_clocks_update_dpp_dto
to check each instance and compare previous clock to new clock.
If new clock is higher than previous clock, program DPPDTO.
