This patch addresses Interrupts from south display engine (SDE).
ICP has two registers - SHOTPLUG_CTL_DDI and SHOTPLUG_CTL_TC.
Introduce these registers and their intended values.
Introduce icp_irq_handler().
The icp_irq_postinstall() takes care of
enabling all PCH interrupt sources, to unmask
them as needed with SDEIMR, as is done
done by ibx_irq_pre_postinstall() for earlier platforms.
We do not need to explicitly call the ibx_irq_pre_postinstall().
Also, while changing these,

v2:
- remove redundant register defines.(Lucas)
- Change register names to be more consistent with
previous platforms (Lucas)
v3:
-Reorder bit defines to a more appropriate location.
Change the comments. Confirm in the commit message that
icp_irq_postinstall() need not go to
ibx_irq_pre_postinstall() and ibx_irq_postinstall()
as in earlier platforms. (Paulo)

Current "old" method to find engine worked pretty well for DE2. However,
it doesn't work when TCON TOP is between mixer (engine) and TCON. TCON
TOP has multiple input ports, but current engine search algorithm
expects only one.
This can be fixed by first looking for output port id and selecting
matching input by subtracting 1 for the next round. This work even if
there is only one input and output.

Currently, amdgpu_do_flip() spinlocks crtc->dev->event_lock and
releases it only after committing updates to the stream.
dc_commit_updates_for_stream() should be moved out of
spinlock for the below reasons:
1. event_lock is supposed to protect access to acrct->pflip_status _only_
2. dc_commit_updates_for_stream() has potential sleep's

Add the definition for ICL power wells and their mapping to power
domains. On ICL there are 3 power well control registers, we'll select
the correct one based on higher bits of the power well ID. The offset
for the control and status flags within this register is based on the
lower bits of the ID as on older platforms.
As the DC state programming is also the same as on old platforms we can
reuse the corresponding helpers. For this we mark here the DC-off power
well as shared among multiple platforms.
Other than the above the delta between old platforms and ICL:
- Pipe C has its own power well, so we can save some additional power in the
pipe A+B and (non-eDP) pipe A configurations.
- Power wells for port E/F DDI/AUX IO and Thunderbolt 1-4 AUX IO
v2:

v4:

needed during driver initialization.

Commit 5422b37c90 ("drm/i915/psr: Kill delays when activating psr
back.") switched from delayed work to the plain variant and while doing so
removed the check for work_busy() before scheduling a PSR activation.
This appears to cause consecutive executions of psr_activate() in this
scenario - after a worker picks up the PSR work item for execution and
before the work function can acquire the PSR mutex, a psr_flush() can
get hold of the mutex and schedule another PSR work. Without a psr_exit()
between the two psr_activate() calls, warning messages get printed.
Further, since we drop the mutex in the midst of psr_work() to wait for
PSR to idle, another work item can also get scheduled. Fix this by
returning if PSR was already active.

So far we got an AUX power domain reference only for the duration of DP
AUX transfers. However, the following suggests that we also need these
for main link functionality:
- The specification doesn't state whether it's needed or not for main
link functionality, but suggests that these power wells need to be
enabled already during display core initialization (Sequences to
Initialize Display).
- For PSR we need to keep the AUX power well enabled.
- On ICL combo PHY ports (non-TC) the AUX power well is needed for
link training too: while the port is enabled with a DP link training
test pattern trying to toggle the AUX power well will time out.
- On ICL MG PHY ports (TC) the AUX power well is needed also for main
link functionality (both in DP and HDMI modes).
- Windows enables these power wells both for main and AUX lane
functionality.
Based on the above take an AUX power reference for main link
functionality too. This makes a difference only on GEN10+ (GLK+)
platforms, where we have separate port specific AUX power wells.
For PSR we still need to distinguish between port A and the other
ports, since on port A DC states must stay enabled for main link
functionality, but DC states must be disabled for driver initiated
AUX transfers. So re-use the corresponding helper from intel_psr.c.
Since we take now a reference for main link functionality on all DP
ports we can forgo taking the separate power ref for PSR functionality.
v2:
- Make sure DC states stay enabled when taking the ref on port A.

v3: (Ville)
- Fix comment about logic for encoders without a crtc state and
add FIXME note for a simplification to avoid calling get_power_domains
in such cases.
- Use intel_crtc_has_dp_encoder() instead !intel_crtc_has_type(HDMI).
