The hardware supports dithering on TCON channel 0 which is used for LCD
panels.
Dithering is a method of approximating a color from a mixture of other
colors when the required color isn't available. It reduces color
banding artifacts that can be observed when displaying gradients
(e.g. grayscale gradients). This may occur when the image that needs
to be displayed is 24-bit but the LCD panel is a lower bit depth and
does not perform dithering on its own.

sun4i_tcon0_mode_set_cpu() currently accepts struct mipi_dsi_device *
as its second parameter. This is derived from drm_encoder.
The DSI encoder is tied to the CPU interface mode of the TCON as a
special case. In theory, if hardware were available, we could also
support normal CPU interface modes. It is better to pass the generic
encoder instead of the specialized mipi_dsi_device, and handle the
differences inside the function.
Passing the encoder would also enable the function to pass it, or any
other data structures related to it, to other functions expecting it.
One such example would be dithering support that will be added in a
later patch, which looks at properties tied to the connector to
determine whether dithering should be enabled or not.

Big amount of changes from Laurent, reworking the driver towards the

of the operations on the display pipeline. The aim of this work is to
allow omapdrm to use the common DRM panels and bridges. Not all of the

The only change visible to the user should be the change in module
dependencies: e.g. earlier a panel module depended on an encoder module,
but now the encoder module depends on the panel module, which affects
the order in which to unload the modules.

Future gen reduce the number of bits we will have available to
differentiate between contexts, so reduce the lifetime of the ID
assignment from that of the context to its current active cycle (i.e.
only while it is pinned for use by the HW, will it have a constant ID).
This means that instead of a max of 2k allocated contexts (worst case
before fun with bit twiddling), we instead have a limit of 2k in flight
contexts (minus a few that have been pinned by the kernel or by perf).
To reduce the number of contexts id we require, we allocate a context id
on first and mark it as pinned for as long as the GEM context itself is,
that is we keep it pinned it while active on each engine. If we exhaust
our context id space, then we try to reclaim an id from an idle context.
In the extreme case where all context ids are pinned by active contexts,
we force the system to idle in order to recover ids.
We cannot reduce the scope of an HW-ID to an engine (allowing the same
gem_context to have different ids on each engine) as in the future we
will need to preassign an id before we know which engine the
context is being executed on.

There are two issues with the current RPCS programming for Icelake:
Expansion of the slice count bitfield has been missed, as well as the
required programming workaround for the subslice count bitfield size
limitation.
1)
Bitfield width for configuring the active slice count has grown so we need
to program the GEN8_R_PWR_CLK_STATE accordingly.
Current code was always requesting eight times the number of slices (due
writing to a bitfield starting three bits higher than it should). These
requests were luckily a) capped by the hardware to the available number of
slices, and b) we haven't yet exported the code to ask for reduced slice
configurations.
Due both of the above there was no impact from this incorrect programming
but we should still fix it.
2)
Due subslice count bitfield being only three bits wide and furthermore
capped to a maximum documented value of four, special programming
workaround is needed to enable more than four subslices.
With this programming driver has to consider the GT configuration as
2x4x8, while the hardware internally translates this to 1x8x8.
A limitation stemming from this is that either a subslice count between
one and four can be selected, or a subslice count equaling the total
number of subslices in all selected slices. In other words, odd subslice
counts greater than four are impossible, as are odd subslice counts
greater than a single slice subslice count.
This also had no impact in the current code base due breakage from 1)
always reqesting more than one slice.
While fixing this we also add some asserts to flag up any future bitfield
overflows.
