[PATCH V9 00/24] drm: sun4i: add Display Engine 3.3 (DE33) support

[Chris Morgan]

From: Chris Morgan <macromorgan at hotmail.com>

I've spoken with Ryan and he agreed to let me take over this series to
get the display engine working on the Allwinner H616. I've taken his
previous patch series for Display Engine 3.3 and combined it with the
LCD controller patch series. I've also fixed a few additional bugs and
made some changes to the device tree bindings.

Changes since V8:
 - Combined the DE33 [1] series and the LCD [2] series to better track
   all patches necessary to output to an LCD display for the Allwinner
   H700.
 - Added a required LVDS reset as requested here [3].
 - Added compatible strings with a fallback for
   allwinner,sun50i-h616-display-engine, allwinner,sun50i-h616-tcon-top,
   and allwinner,sun50i-h616-sram-c.
 - Added binding documentation for the LCD controller.
 - Renamed the de3_sram device tree node to de33_sram.
 - Corrected the LVDS reset for the LCD controller binding.
 - Removed the PWM pins from the pincontroller bindings, as PWM is not
   yet supported.
 - Reordered the patches so that a binding or a device tree node is not
   referenced before it is defined.
