Parse the data lane count out of DT. Limit the supported data lanes
to 1..4 which is the maximum available DSI pairs on the connector of
any known panels which may use this bridge. Internally, this bridge
is an ChipOne ICN6211 which loads its register configuration from a
dedicated storage and its I2C does not seem to be accessible. The
ICN6211 also supports up to 4 DSI lanes, so this is a hard limit.
To avoid any breakage on old DTs where the parsing of data lanes from
DT may fail, fall back to the original hard-coded value of 2 lanes and
warn user.
The lane configuration is preconfigured in the bridge for each of the
WaveShare panels. The 13.3" DSI panel works with 4-lane configuration,
others seem to use 2-lane configuration. This is a hardware property,
so the actual count should come from DT.

Add a has_access_counter feature flag to the graphics IP descriptor
and skip writing parameters for the access counter queue in
guc_um_init_params(), leaving queue_params[2] zero-initialized
to signal unavailability to the GuC.
The queue_params[] array layout is fixed by firmware ABI, so we
maintain the structure with queues 0 and 1 (page fault request/response)
always configured, and queue 2 conditionally skipped based on the
has_access_counter flag.

When computing the encoder/CRTC state multiple times, such as during
iteration over the possible pipe joiner configurations, it must be
ensured that all state is explicitly initialized each time. At the
moment, this is not guaranteed for the DSC/FEC state within the
encoder/CRTC state. In one iteration trying a pipe joiner configuration,
the DSC state may get initialized without computing the full
CRTC/encoder state due to the given joiner configuration being
impossible. When the same CRTC/encoder state is recomputed in a
subsequent iteration, the previously set non-zero - now stale - DSC/FEC
state may still be present, which is unexpected if a non-DSC
configuration is being computed.
This can lead to a DSC state mismatch error if multiple joiner
configurations are evaluated and the working configuration ultimately
turns out to be a non-DSC one.
Follow the existing pattern and compute the full (DSC/FEC) state on all
code paths (including now the non-DSC path as well) to fix the issue.

Replace the internal DRM framebuffer with a DRM client buffer. The
client buffer allocates the DRM framebuffer on a file and also uses
GEM object handles via the regular ADDFB2 interfaces. This unifies
framebuffer allocation for clients in user space and gma500's internal
fbdev emulation.
Also simplify the clean-up side of the fbdev emulation.
Later patches will allow for streamlining gma500's framebuffer code and
DRM's fbdev emulation in general.

Replace the geometry and size calculation in gma500's fbdev emulation
with DRM format helpers. This consists of 4CC lookup from the fbdev
parameters, format loockup, pitch calculation and size calculation.
Then allocate the GEM buffer object for the framebuffer memory from
the calculated size.
As before, fallback to 16-bit colors if the stolen memory is insufficient
for 32-bit colors. But look at the result from psb_gem_create() instead
of guessing before the allocation. The new method is more reliable when
others allocate from stolen video memory (e.g., cursors).
Set up mode_cmd with the calculated values just before allocating the
framebuffer. This code will later be replaced with a DRM client buffer.

In order to avoid any probe ordering issue, the best practice is to move
the secondary MIPI-DSI device registration and attachment to the
MIPI-DSI host at probe time.
Besides solving the probe ordering problems, this makes the bridge work
with R-Car DU. The R-Car DU will attempt to locate the DSI host bridge in
its own rcar_du_probe()->rcar_du_modeset_init()->rcar_du_encoder_init()
by calling of_drm_find_bridge() which calls of_drm_find_and_get_bridge()
and iterates over bridge_list to locate the DSI host bridge.
However, unless the WS driver calls mipi_dsi_attach() in probe(), the
DSI host bridge .attach callback rcar_mipi_dsi_host_attach() is not
called and the DSI host bridge is not added into bridge_list. Therefore
the of_drm_find_and_get_bridge() called from du_probe() will never find
the DSI host bridge and probe will indefinitelly fail with -EPROBE_DEFER.
The circular dependency here is, that if rcar_du_encoder_init() would
manage to find the DSI host bridge, it would call the WS driver .attach
callback ws_bridge_bridge_attach(), but this is too late and can never
happen. This change avoids the circular dependency.

Introduce gpu_buddy_assert(), a small helper that wraps WARN_ON() and,
when CONFIG_KUNIT is enabled, also calls kunit_fail_current_test() so
that any active KUnit test is marked as failed. In non-KUnit builds
the macro reduces to WARN_ON(), preserving existing behaviour.
Stringify the asserted condition in the failure message to make it easy
to identify which assertion fired. Leave the WARN_ON() in
gpu_buddy_block_trim() unchanged, as it returns -EINVAL and the caller
already observes the failure via the return code.

Clang warns that comparing a __u16 value against 65536 is always false.
num_syncobj_handles is defined as __u16 in both the userq signal and
wait ioctl argument structs, so it can never exceed 65535. The checks
against AMDGPU_USERQ_MAX_HANDLES are therefore redundant and trigger
-Wtautological-constant-out-of-range-compare.
Fixes: Clang -Wtautological-constant-out-of-range-compare in userq
signal/wait ioctls
Fixes: d8e760b7996d ("drm/amdgpu: update type for num_syncobj_handles in drm_amdgpu_userq_signal")
Fixes: c561d2320492 ("drm/amdgpu: update type for num_syncobj_handles in drm_amdgpu_userq_wait")
