[Why]
To support feature that calculates CRTC CRC value on specific
region (crc window).
[How]
1. Use debugfs to specify crtc crc window
2. Use vline0 IRQ to write crtc crc window

amdgpu DM handles INTERRUPT_LOW_IRQ_CONTEXT interrupt(hpd, hpd_rx) by using work
queue and uses single work_struct. If new interrupt is recevied before the
previous handler finished, new interrupts(same type) will be discarded and
driver just sends "amdgpu_dm_irq_schedule_work FAILED" message out. If some
important hpd, hpd_rx related interrupts are missed by driver the hot (un)plug
devices may cause system hang or instability, such as issues with system
resume from S3 sleep with mst device connected.
This patch dynamically allocates new amdgpu_dm_irq_handler_data for new
interrupts if previous INTERRUPT_LOW_IRQ_CONTEXT interrupt work has not been
handled. So the new interrupt works can be queued to the same workqueue_struct,
instead of discard the new interrupts. All allocated amdgpu_dm_irq_handler_data
are put into a single linked list and will be reused after.

[WHY]
To process AUX transactions with DMUB using inbox1 and outbox1 mail boxes.
[HOW]
1) Added inbox1 command DMUB_CMD__DP_AUX_ACCESS to issue AUX commands
to DMUB in dc_process_dmub_aux_transfer_async(). DMUB processes AUX cmd
with DCN and sends reply back in an outbox1 message triggering an
outbox1 interrupt to driver.
2) In existing driver implementation, AUX commands are processed
synchronously by configuring DCN reg. But in DMUB AUX, driver sends an
inbox1 message and waits for a conditional variable (CV) which will be
signaled by outbox1 ISR.
3) As the driver holds dal and dc locks while waiting for CV, the outbox1
ISR is registered with noMutexWait set to true, which allows ISR to run
and signal CV. This sets a constraint on ISR to not modify variables
such as dc, dmub, etc.
4) Created dmub_outbox.c with dmub_enable_outbox_notification() to enable
outbox1 mailbox.
5) New mailbox address ranges allocated for outbox1 of size DMUB_RB_SIZE.
Created dmub functions for Outbox1: dmub_dcn20_setup_out_mailbox(),
dmub_dcn20_get_outbox1_wptr() and dmub_dcn20_set_outbox1_rptr().
6) Added functions dc_stat_get_dmub_notification() and
dmub_srv_stat_get_notification() to retrieve Outbox1 message.
7) Currently, DMUB doesn't opens DDC in AUX mode before issuing AUX
transaction. A workaround is added in dce_aux_transfer_dmub_raw() to
open in DDC in AUX mode for every AUX transaction.
8) Added dc debug option enable_dmub_aux_for_legacy_ddc enable/disable
DMUB AUX. This debug option is checked dce_aux_transfer_with_retries()
to select the method to process AUX transactions.

[Why]
A seamless transition between modes can be performed if the new incoming
mode has the same timing parameters as the optimized mode on a display with a

Smooth video playback usecases can be enabled with this seamless transition by
switching to a new mode which has a refresh rate matching the video.

[Why]
While possible for userspace to create and add custom mode based off the
optimized mode for the connected display which differs only in front porch
timing, this patch set adds a list of common video modes in advance.
The list of common video refresh rates is small, well known and the optimized
mode has specific requirements to be able to enable HW frame doubling and
tripling so it makes most sense to create the modes that video players will need
in advance. The optimized mode matches the preferred mode resolution but has the
highest refresh rate available to enable the largest front porch extension.
[How]
Find the optimized mode and store it on the connector so we can check it
later during our optimized modeset.
Prepopulate the mode list with a list of common video mades based on the
optimized mode (but with a longer front porch) if the panel doesn't support a
variant of the mode natively.

context is what is applied to the HW so we should be re-using this
rather than creating a new context.
Recreating the context can lead to mismatch between new context and the
current context
For example: gsl groups get changed when we create a new context this
can cause issues in a multi display config (with flip immediate) because
we don't align the existing gsl groups in the new and current context.
If we reuse the current context the gsl group assignment stays the same.
[How]
Instead of discarding the current context, we instead just copy the
current state and add/remove planes and streams.

[Why]
Find out when we try to disable CRC calculation, crc generation is still
enabled. Main reason is that dc_stream_configure_crc() will never get
called when the source is AMDGPU_DM_PIPE_CRC_SOURCE_NONE.
[How]
Add checking condition that when source is
AMDGPU_DM_PIPE_CRC_SOURCE_NONE, we should also call
dc_stream_configure_crc() to disable crc calculation.
