dc50165601 drm/ttm/tests: Set DMA mask in KUnit device 
In commit d393acce7b ("drm/tests: Switch to kunit devices"),
DRM test helpers migrated away from using a dummy platform driver
in favour of KUnit device. This means that DMA masks for the device
are not set but are required by ttm_pool_alloc tests.

Set the DMA mask for coherent mappings to unblock testing.

588c4c8d58 drm/ttm/tests: Fix a warning in ttm_bo_unreserve_bulk 
BOs in a bulk move have to share the same reservation object. That is
not the case in the ttm_bo_unreserve_bulk subtest. Update
ttm_bo_kunit_init() helper to accept dma_resv object so we can define
buffer objects that share the same resv. Update calls to that helper
accordingly.

With new connector model, tc358767 will not create the connector, when
DRM_BRIDGE_ATTACH_NO_CONNECTOR is set and display-controller driver will

Add the missing bus format negotiation hooks in the
drm_bridge_funcs to complete DRM_BRIDGE_ATTACH_NO_CONNECTOR support.

Output format, for DPI/DSI to DP, is selected to
MEDIA_BUS_FMT_RGB888_1X24 as default, keeping in mind what the older
model used to support.

TTM_BO_VM_NUM_PREFAULT more pages beforehand

However, on some platform the page faults are more costly, this

When multiple levels of page table is supported, the new default

f85376c890 drm/ttm/tests: Let ttm_bo_test consider different ww_mutex implementation. 
PREEMPT_RT has a different locking implementation for ww_mutex. The
base mutex of struct ww_mutex is declared as struct WW_MUTEX_BASE. The
latter is defined as `mutex' for non-PREEMPT_RT builds and `rt_mutex'
for PREEMPT_RT builds.

Using mutex_lock() directly on the base mutex in
ttm_bo_reserve_deadlock() leads to compile error on PREEMPT_RT.

The locking-selftest has its own defines to deal with this and it is
probably best to defines the needed one within the test program since
their usefulness is limited outside of well known selftests.

Provide ww_mutex_base_lock() which points to the correct function for
PREEMPT_RT and non-PREEMPT_RT builds.

This will make it easier for Linux distributions to enable drm_panic

The only drawback is that fbcon won't display the boot kmsg, so it
should rely on userspace to do that.

0743dafefd drm: zynqmp_kms: Fix AUX bus not getting unregistered 
drm_encoder_cleanup is responsible for calling drm_bridge_detach for
each bridge attached to the encoder. zynqmp_dp_bridge_detach is in turn
responsible for unregistering the AUX bus. However, we never ended up
calling drm_encoder_cleanup in the remove or error paths, so the AUX bus
would stick around after the rest of the driver had been removed.

I don't really understand why drm_mode_config_cleanup doesn't call
drm_encoder_cleanup for us. It will call destroy (which for
simple_encoder is drm_encoder_cleanup) on encoders in the mode_config's
encoder_list.

Should drm_encoder_cleanup get called before or after
drm_atomic_helper_shutdown?

update callback. Setting the new display mode may require disabling and
re-enabling the CRTC. This effectively resets DPSUB to the default state
with all layers disabled. The original implementation of the plane atomic
update enables the corresponding DPSUB layer only if the framebuffer
format has changed. This would leave the layer disabled after switching to
a different display mode with the same framebuffer format.

a19bffb10c accel/ivpu: Implement DCT handling 
When host system is under heavy load and the NPU is already running
on the lowest frequency, PUNIT may request Duty Cycle Throttling (DCT).
This will further reduce NPU power usage.

PUNIT requests DCT mode using Survabilty IRQ and mailbox register.
The driver then issues a JSM message to the FW that enables
the DCT mode. If the NPU resets while in DCT mode, the driver request
DCT mode during FW boot.

Also add debugfs "dct" file that allows to set arbitrary DCT percentage,
which is used by driver tests.
