[PATCH 0/8] ARM: sun9i: a80: Add display support

[Chen-Yu Tsai <wens@csie.org>]

Hi everyone,

This series adds basic support for the display pipelines found on the
Allwinner A80 SoC. Currently only parallel RGB output via TCON0 is
supported. TCON1 drives the HDMI encoder, which I've not been able to
get working yet.

Patch 1 adds device tree bindings for the TCONs on the A80. In
particular, TCON0 requires the eDP reset control in addition to its own.

Patch 2 adds a device tree binding for the Detail Enhancement Unit found
only on the A80.

Patch 3 adds driver support for the TCONs.

Patch 4 adds compatible strings to the device tree bindings for all the 
remaining peripherals covered by this series.

Patch 5 adds support for the compatible strings from the previous patch
to the sun4i-drm driver.

Patch 6 adds the display pipeline device nodes to the A80 .dtsi file.

Patch 7 adds a pinmux setting for RGB888 output for TCON0.

Patch 8 enables VGA output on the Cubieboard4 via an external DAC and
an I2C bus from the SoC for DDC.


I've had these patches for quite some time now, rebasing them as more
features were added to sun4i-drm. Please have a look.


Regards
ChenYu
