Document the Synaptics TDDI (Touch/Display Integration) panel hardware.
Along with the MIPI-DSI panel, these devices also have an in-built LED
backlight device and a touchscreen, all packed together in a single chip.
Also, add compatibles for supported panels - TD4101 and TD4300. Both
have the '-panel' suffix so as to remove any ambiguity between the panel
and touchscreen chips.

Add panel driver used in the OnePlus 6T.
No datasheet, based mostly on EDK2 init sequence and the downstream driver.
Note: This driver doesn't use previously mentioned "samsung,s6e3fc2x01"
by OnePlus 6T device-tree.
The reason is because DDIC itself without knowing the panel type used
with it will not give the driver enough information about the panel used,
as the panel cannot be autodetected.
While would be more practical to support the original compatible,
I would like to avoid it, to prevent confusing devs upstreaming DDICs.

Add a driver for Arm Ethos-U65/U85 NPUs. The Ethos-U NPU has a
relatively simple interface with single command stream to describe
buffers, operation settings, and network operations. It supports up to 8
memory regions (though no h/w bounds on a region). The Ethos NPUs
are designed to use an SRAM for scratch memory. Region 2 is reserved
for SRAM (like the downstream driver stack and compiler). Userspace
doesn't need access to the SRAM.
The h/w has no MMU nor external IOMMU and is a DMA engine which can
read and write anywhere in memory without h/w bounds checks. The user
submitted command streams must be validated against the bounds of the
GEM BOs. This is similar to the VC4 design which validates shaders.
The job submit is based on the rocket driver for the Rockchip NPU
utilizing the GPU scheduler. It is simpler as there's only 1 core rather
than 3.
Tested on i.MX93 platform (U65) and FVP (U85) with Mesa Teflon
support.

When calling drm_client_release(), the client is already quiescent.
Internal locks should therefore be dropped before the caller releases
the client.
In the case of the DRM log, concurrency originates from the console or
from client events. The console has been unregistered in the previous
line. The caller of the unregister callback, drm_log_client_unregister(),
holds clientlist_mutex from struct drm_device to protect against concurrent
client events. It is therefore safe to release the client without holding
locks.

Fbdev emulation allocates and prepares client memory in

When a connector is created, add a `status` file to allow to update the
connector status to:
- 1 connector_status_connected
- 2 connector_status_disconnected
- 3 connector_status_unknown
If the device is enabled, updating the status hot-plug or unplugs the
connector.

Allow to store the connector status in vkms_config_connector and add a
getter and a setter functions as well a KUnit test.
This change only adds the configuration, the connector status is not
used yet.
