Optional properties:
- clock-master: boolean. Should be enabled if the host is being used in
conjunction with another DSI host to drive the same peripheral. Hardware
supporting such a configuration generally requires the data on both the busses

Example
-------
Peripherals with a different control bus
----------------------------------------
There are peripherals that have I2C/SPI (or some other non-DSI bus) as the
primary control bus, but are also connected to a DSI bus (mostly for the data
path). Connections between such peripherals and a DSI host can be represented
using the graph bindings [1], [2].
Peripherals that support dual channel DSI
-----------------------------------------
Peripherals with higher bandwidth requirements can be connected to 2 DSI
busses. Each DSI bus/channel drives some portion of the pixel data (generally
left/right half of each line of the display, or even/odd lines of the display).
The graph bindings should be used to represent the multiple DSI busses that are
connected to this peripheral. Each DSI host's output endpoint can be linked to
an input endpoint of the DSI peripheral.

Clean up the DRM header mess
----------------------------
Currently the DRM subsystem has only one global header, ``drmP.h``. This is
used both for functions exported to helper libraries and drivers and functions
only used internally in the ``drm.ko`` module. The goal would be to move all
header declarations not needed outside of ``drm.ko`` into
``drivers/gpu/drm/drm_*_internal.h`` header files. ``EXPORT_SYMBOL`` also
needs to be dropped for these functions.
This would nicely tie in with the below task to create kerneldoc after the API
is cleaned up. Or with the "hide legacy cruft better" task.
Note that this is well in progress, but ``drmP.h`` is still huge. The updated
plan is to switch to per-file driver API headers, which will also structure
the kerneldoc better. This should also allow more fine-grained ``#include``
directives.
The DRM subsystem originally had only one huge global header, ``drmP.h``. This
is now split up, but many source files still include it. The remaining part of
the cleanup work here is to replace any ``#include <drm/drmP.h>`` by only the
headers needed (and fixing up any missing pre-declarations in the headers).
In the end no .c file should need to include ``drmP.h`` anymore.

Hide legacy cruft better
------------------------
Way back DRM supported only drivers which shadow-attached to PCI devices with
userspace or fbdev drivers setting up outputs. Modern DRM drivers take charge
of the entire device, you can spot them with the DRIVER_MODESET flag.
Unfortunately there's still large piles of legacy code around which needs to
be hidden so that driver writers don't accidentally end up using it. And to
prevent security issues in those legacy IOCTLs from being exploited on modern
drivers. This has multiple possible subtasks:
* Extract support code for legacy features into a ``drm-legacy.ko`` kernel
module and compile it only when one of the legacy drivers is enabled.
This is mostly done, the only thing left is to split up ``drm_irq.c`` into
legacy cruft and the parts needed by modern KMS drivers.

Extend virtual test driver (VKMS)
---------------------------------
Create a virtual KMS driver for testing (vkms)
----------------------------------------------
With all the latest helpers it should be fairly simple to create a virtual KMS
driver useful for testing, or for running X or similar on headless machines
(to be able to still use the GPU). This would be similar to vgem, but aimed at
the modeset side.
Once the basics are there there's tons of possibilities to extend it.
See the documentation of :ref:`VKMS <vkms>` for more details. This is an ideal
internship task, since it only requires a virtual machine and can be sized to
fit the available time.

- Optimize CRC computation ``compute_crc()`` and plane blending ``blend()``
- Use the alpha value to blend vaddr_src with vaddr_dst instead of
overwriting it in ``blend()``.

- Add igt test to check extreme alpha values i.e. fully opaque and fully
