drm/amd/display: Refactor CRTC interrupt toggling logic

[Why]
The vblank and pageflip interrupts should only be enabled for a CRTC
that's enabled and has active planes.

The current logic takes care of this, but isn't setup to handle the case
where the active plane count goes to zero but the stream remains
enabled.

We currently block this case since we don't allow commits that enable a
CRTC with no active planes, but shouldn't be any reason we can't support
this from a hardware perspective and many userspace applications expect
to be able to do it (like IGT).

[How]
The count_crtc_active_planes function fills in the number of
"active_planes" on the dm_crtc_state. This should be the same as
DC's plane_count on the stream_status but easier to access since we
don't need to lock the private atomic state with the DC context.

Add the "interrupts_enabled" flag to the dm_crtc_state and set it based
on whether the stream exists and if there are active planes on the
stream.

Update the disable and enable logic to make use of this new flag.

There shouldn't be any functional change (yet) with this patch.

drm/amd/display: Use surface directly when checking update type

[Why]
DC expects the surface memory address to identify the surface.

This doesn't work with what we're doing with the temporary surfaces,
it will always assume this is a full update because the surface
isn't in the current context.

[How]
Use the surface directly. This doesn't give us much improvement yet,
since we always create a new dc_plane_state when state->allow_modeset
is true.

The call into dc_check_update_surfaces_for_stream also needs to be
locked, for two reasons:

1. It checks the current DC state
2. It modifies the surface update flags

Both of which could be currently in the middle of commit work from
commit tail.

A TODO here is to pass the context explicitly into this function and

drm/amd/display: Rework DC plane filling and surface updates

[Why]
We currently don't do DC validation for medium or full updates where
the plane state isn't created. There are some medium and full updates
that can cause bandwidth or clock changes to occur resulting in
underflow or corruption.

We need to be able to fill surface and plane info updates during
atomic commit for dm_determine_update_type for commit. Since we already
do this during atomic commit tail it would be good if we had the same
logic in both places for creating these structures.

[How]
Introduce fill_dc_scaling_info and fill_dc_plane_info_and_addr.
These two functions cover the following three update structures:

- struct dc_scaling_info
- struct dc_plane_info
- struct dc_plane_address

Cleanup and adapter the existing fill_plane_* helpers to work with
these functions.

Update call sites that used most of these sub helpers directly to work
with the new functions. The exception being prepare_fb - we just want
the new buffer attributes specifically in the case where we're
creating the plane. This is needed for dc_commit_state in the case
where the FB hasn't been previously been used.

This isn't quite a refactor, but functionally driver behavior should
be mostly the smae as before. The one exception is that we now check
the return code for fill_plane_buffer_attributes which means that
commits will be rejected that try to enable DCC with erroneous
parameters.

drm/amd/display: Recalculate pitch when buffers change

[Why]
Pitch was only calculated based on format whenever the plane state

drm/amd/display: Maintain z-ordering when creating planes

[Why]
The overlay will be incorrectly placed *below* the primary plane for
commits with state->allow_modeset = true because the primary plane
won't be removed and recreated in the same commit.

[How]
Add the should_reset_plane helper to determine if the plane should be
reset or not. If we need to add or force reset any plane in the context
then we'll need to do the same for every plane on the stream.

Unfortunately we need to do the remove / recreate routine for removing
planes as well since DC currently isn't well equipped to handle the
plane with the top pipe being removed with other planes still active.

drm/amd/display: Update plane scaling parameters for fast updates

[Why]
Plane scaling parameters are not correctly filled or updated when
performing fast updates.

They're filled when creating the dc plane state and during atomic check.

While the atomic check code path happens for the plane even during fast
updates, the issue is that they're done in place on the dc_plane_state
directly. This dc_plane_state may be the current state plane state
being used by the hardware, so these parameters won't be correctly
programmed.

The new scaling parameters should instead be passed as an update
to the plane.

[How]
Update fill_rects_from_plane_state to not modify dc_plane_state
directly. Update the call sites that use this to fill in the appropriate
values.

In addition - during full plane updates - all necessary pipes should be

drm/amd/display: Recreate private_obj->state during S3 resume

[Why]

When entering S3, amdgpu first calls DRM to cache the current atomic
state, then commit the 'all-disabled' state. This sets dc->current_state
to point at the private atomic object's dm_atomic_state->context, as
any regular atomic commit would.

Afterwards, amdgpu_dm calls dc_set_power_state() with S3 power state.
This invalidates dc->current_state by wiping it to 0, consequently
wiping dm_atomic_state->context.

During resume, the cached atomic state is restored. When getting the
private object however, the dm_atomic_state - containing the wiped
context - is duplicated into the atomic state. This causes DC validation
to fail during atomic check, as necessary function pointers in dc_state
are now NULL.

[How]

Recreate the private object's dm_atomic_state->context during resume,
restoring any static values such as function pointers.

A TODO item is added to move static read-only values out of dc_state -
they shouldn't be there anyways.

drm/amd/display: Initialize stream_update with memset

The brace initialization used here generates warnings on some
compilers. For example, on GCC 4.9:

[...] In function ‘dm_determine_update_type_for_commit’:
[...] error: missing braces around initializer [-Werror=missing-braces]
   struct dc_stream_update stream_update = { 0 };
          ^

Use memset to make this more portable.

v2: Specify the compiler / diagnostic in the commit message (Paul)

drm/meson: Add G12A support for the DW-HDMI Glue

The Amlogic G12A embeds the same Synopsys DW-HDMI Controller,
but with :
- a "backport" of the HDR signaling registers from more recent
  DW-HDMI controllers, this will need a tweak since it's not
  normally present on this version of the DW-HDMI controller
- A direct mapping of TOP and DW-HDMI registers instead of an
  internal bus accessed using read/write registers
- Support for RX-SENSE, but not yet implemented
- Support for HDMI 2.1 Dynamic HDR, but not yet implemented
- Different registers mapping for the HDMI PHY setup

This patchs adds support for these changes while providing exact
same support as the previous GXBB, GXL & GXM SoCs.

where the HDMI PLL needs a specific setup to handle correctly the
5.94GHz DCO frequency.

Apart that, it handls ecorrectly all the other HDMI frequencies
