[PATCH 00/18] drm/sun4i: Allwinner MIPI-DSI support

[Maxime Ripard]

Hi,

Here is an preliminary version of the MIPI-DSI support for the Allwinner
SoCs.

This controller can be found on a number of recent SoCs, such as the
A31, A33 or the A64.

Given the sparse documentation, there's a number of obscure areas, but
the current implementation has been tested with a 4-lanes DSI panel on
an A33.

In order to support properly the DSI controller, we also had to rework a
bit the TCON code to ease the encoders support. The support is a bit rough
around the edges at the time, and some artifacts are still shown on the
screen for some reasons. Wider testing with different display will
hopefully nail those down.

It depends for the moment on the clock protection serie sent by Jerome
Brunet:

Let me know what you think,
Maxime
