To make NV12 working on icl, we need to update 2 planes simultaneously.
I've chosen to do this in the CRTC step after plane validation is done,
so we know what planes are (in)visible. The linked Y plane will get
updated in intel_plane_update_planes_on_crtc(), by the call to
update_slave, which gets the master's plane_state as argument.
The link requires both planes for atomic_update to work,

- Introduce icl_is_nv12_y_plane(), instead of hardcoding sprite numbers.
- Put all the state updating login in intel_plane_atomic_check_with_state().

Replace the kvmalloc_array() with i915_gem_object_get_dma_address() when

To calculate the size of the radix tree I think we can do
something like this (assuming 64bit pointers):
num_pages = obj_size / 4096
tree_height = ceil(log64(num_pages))
num_nodes = sum(64^n, n, 0, tree_height-1)
tree_size = num_nodes * 576
If we compare that with the object size we should get a relative
overhead of around .2% to 1% for reasonable sized objects,
which framebuffers tend to be.

drm/i915: GEM_WARN_ON considered harmful
GEM_WARN_ON currently has dangerous semantics where it is completely
compiled out on !GEM_DEBUG builds. This can leave users who expect it to
be more like a WARN_ON, just without a warning in non-debug builds, in
complete ignorance.
Another gotcha with it is that it cannot be used as a statement. Which is
again different from a standard kernel WARN_ON.
This patch fixes both problems by making it behave as one would expect.
It can now be used both as an expression and as statement, and also the
condition evaluates properly in all builds - code under the conditional
will therefore not unexpectedly disappear.
To satisfy call sites which really want the code under the conditional to
completely disappear, we add GEM_DEBUG_WARN_ON and convert some of the
callers to it. This one can also be used as both expression and statement.
>From the above it follows GEM_DEBUG_WARN_ON should be used in situations
where we are certain the condition will be hit during development, but at
a place in code where error can be handled to the benefit of not crashing
the machine.
GEM_WARN_ON on the other hand should be used where condition may happen in
production and we just want to distinguish the level of debugging output
emitted between the production and debug build.

drm/atomic_helper: Stop modesets on unregistered connectors harder
Unfortunately, it appears our fix in:
commit
b5d29843d8ef ("drm/atomic_helper: Allow DPMS On<->Off changes
for unregistered connectors")
Which attempted to work around the problems introduced by:
commit
4d80273976bf ("drm/atomic_helper: Disallow new modesets on
unregistered connectors")
Is still not the right solution, as modesets can still be triggered
outside of drm_atomic_set_crtc_for_connector().
So in order to fix this, while still being careful that we don't break
modesets that a driver may perform before being registered with
userspace, we replace connector->registered with a tristate member,
connector->registration_state. This allows us to keep track of whether
or not a connector is still initializing and hasn't been exposed to
userspace, is currently registered and exposed to userspace, or has been
legitimately removed from the system after having once been present.
Using this info, we can prevent userspace from performing new modesets
on unregistered connectors while still allowing the driver to perform
modesets on unregistered connectors before the driver has finished being
registered.
Changes since v1:
- Fix WARN_ON() in drm_connector_cleanup() that CI caught with this
patchset in igt@drv_module_reload@basic-reload-inject and
igt@drv_module_reload@basic-reload by checking if the connector is
registered instead of unregistered, as calling drm_connector_cleanup()
on a connector that hasn't been registered with userspace yet should
stay valid.
- Remove unregistered_connector_check(), and just go back to what we
were doing before in commit
4d80273976bf ("drm/atomic_helper: Disallow
new modesets on unregistered connectors") except replacing
READ_ONCE(connector->registered) with drm_connector_is_unregistered().
This gets rid of the behavior of allowing DPMS On<->Off, but that should
be fine as it's more consistent with the UAPI we had before - danvet
- s/drm_connector_unregistered/drm_connector_is_unregistered/ - danvet
- Update documentation, fix some typos.

drm/i915: Add YCBCR 4:2:0/4:4:4 support for LSPCON
LSPCON chips can generate YCBCR outputs, if asked nicely :).
In order to generate YCBCR 4:2:0 outputs, a source must:
- send YCBCR 4:4:4 signals to LSPCON
- program color space as 4:2:0 in AVI infoframes
Whereas for YCBCR 4:4:4 outputs, the source must:
- send YCBCR 4:4:4 signals to LSPCON
- program color space as 4:4:4 in AVI infoframes
So for both 4:2:0 as well as 4:4:4 outputs, we are driving the
pipe for YCBCR 4:4:4 output, but AVI infoframe's color space
information indicates LSPCON FW to start scaling down from YCBCR
4:4:4 and generate YCBCR 4:2:0 output. As the scaling is done by
LSPCON device, we need not to reserve a scaler for 4:2:0 outputs.
V2: rebase
V3: Addressed review comments from Ville
- add enum crtc_output_format instead of bool ycbcr420
- use crtc_output_format=4:4:4 for modeset of LSPCON 4:2:0 output
cases in this way we will have YCBCR 4:4:4 framework ready (except
the ABI part)
V4: Added r-b from Maarten (for v3)
Addressed review comments from Ville:
- Do not add a non-atomic state variable to determine lspcon output.
Instead add bool in CRTC state to indicate lspcon based scaling.
V5: Addressed review comments from Ville:
- Change the state bool name from external scaling to something more
relavent.
- Keep the info and adjusted_mode structures const.
- use crtc_state instead of pipe_config.
- Push all the config change into lspcon_ycbcr420_config function.
