Commit 47b5ac7daa ("drm/atomic: Add new atomic_create_state callback
to drm_private_obj") introduced a new pattern for allocating drm object
states: atomic_create_state, a dedicated hook that allocates and
initializes a pristine state without any side effect.
The bridge atomic_reset callback is already fallible and in practice
only allocates and initializes state without touching hardware.
However, the reset name does not make this contract clear: callers
and implementers cannot tell from the name alone whether the hardware
will be affected or when the hook is safe to call.
Add an atomic_create_state callback to drm_bridge_funcs to make the
contract explicit: allocate a pristine state, initialize it, no side
effects. The core calls it when available, falling back to
atomic_reset otherwise.

The convention for state init helpers is to pass the state pointer
as the first argument and the object pointer second.
__drm_atomic_helper_bridge_state_init() has them in the opposite
order. Swap the arguments to follow the convention, and update the
cdns-mhdp8546 caller.

__drm_atomic_helper_bridge_reset() is used to initialize a
newly allocated drm_bridge_state, and is being typically called by the
drm_bridge_funcs.atomic_reset implementation.
Since we want to consolidate DRM objects state allocation around the
atomic_create_state callback that will only allocate and initialize a
new drm_bridge_state instance, we will need to call
__drm_atomic_helper_bridge_reset() from both the atomic_reset and
atomic_create_state hooks.
To avoid any confusion, we can thus rename
__drm_atomic_helper_bridge_reset() to
__drm_atomic_helper_bridge_state_init().

The drm_bridge_funcs.atomic_reset documentation states that the hook
must return either a valid drm_bridge_state object or an ERR_PTR().
The cdns_mhdp_bridge_atomic_reset() callback returns NULL when the
allocation of its state fails, violating this contract.
Return ERR_PTR(-ENOMEM) instead.

Lets simplify and make clearer the fence lock cycling workaround in
nouveau_cli_work().
The reason for the workaround is that the worker processes the list of
pending work items (and so fence callbacks) opportunisticaly, while
dma_fence_is_signaled() returns true as soon as a the fence is signaled.
It is therefore not allowed for the opportunistic processing to free the
work item, since the fence callback processing can still be in the process
of dereferencing work->cb.
This wasn't very clear in the code so clarify it with a nice comment.
In the process we replace the somewhat interleaved and not very readable
nouveau_cli_work_ready() helper with a direct dma_fence_is_signaled, which
is even faster since it removes the lock cycling from the unsignaled fence
path.

We've had an unknown Turing issue for a while with page faults since
large pages and compression.
I've got a patch series that syncs all our L2 handling with ogkm and it
made this fault happen more.
After writing a bunch of debugging patches, I spotted an invalid LPT
entry where there should have been a valid one.
A 64K MAP succeeds on a range, but a subsequent SPT put drops SPT refs
across multiple ranges,
We shouldn't assume all ranges where SPTEs go away will have the same
sparse/invalid/valid state, just iterate over each instead and do the
right thing.

In the non-uvmm path, there could be a race between the info lookup

The backlight, when managed by the panel controller, could be powered by
an external regulator, and shutting down the regulator could power off
the backlight.
Add support for such a regulator. It's powered off when the backlight is
0 (either by setting brightness to 0 or setting bl_power), and powered
on when the backlight should be operating.

When the backlight is managed by the panel controller IC, an external
power rail might be powering the backlight.
Add an optional `bl-supply` property to describe such power rail, thus
allow disabling the backlight.

This adds support for the ICNA3512 and ICNA3520 DDICs used in both the
AYN Odin 2 Portal and Ayaneo Pocket DS top panel respectively and for
for both the AYN Odin 3 and the AYN Thor top panel respectively.
These all have unique compatibles because the panels themselves are
likely unique hardware with only the ddic's and thus api and driver
handling shared.

The Chipone ICNA3512 and ICNA3520 DDICs are high refresh, low power
MIPI-DSI drivers for OLED panels. The icna3512 is used by the Ayn Odin 2
Portal and the Ayaneo Pocket DS top panel while the icna3520 is used by
the Ayn Thor top panel and the Ayn Odin 3.
These ddic's are generally compatible, but some MIPI vendor commands
differ between them, so they are not fully fallback compatible.
