[PATCH 1/3] drm/panel: Add RGB666 variant of Innolux AT070TN90

[Paul Kocialkowski]

This adds timings for the RGB666 variant of the Innolux AT070TN90 panel,
as found on the Ainol AW1 tablet.

The panel also supports RGB888 output. When RGB666 mode is used instead,
the two extra lanes per component are grounded.

In the future, it might become necessary to introduce a dedicated
device-tree property to specify the bus format and maybe specify it in
the mode description instead of panel description so that the
appropriate mode can be selected for each bus format.

[PATCH 2/3] ARM: dts: sun7i: Add RGB666 pins definition

[Paul Kocialkowski]

This adds the pins definition for RGB666 LCD panels on the A20. It was
inspired by the A33 definition, that concernes the same set of pins.

[PATCH 3/3] ARM: dts: sun7i: Add support for the Ainol AW1 tablet

[Paul Kocialkowski]

This adds support for the Ainol AW1, an A20-based 7" tablet from Ainol.

The following board-specific features are supported:
* LCD panel
* Backlight
* USB OTG
* Buttons
* Touchscreen (doesn't work without non-free firmware)
* Accelerometer
* Battery

The following are untested:
* Audio output
* Audio speakers
* USB via SPCI connector

The following are not supported:
* Wi-Fi
* Bluetooth
* NAND
* Audio via SPCI connector
* Audio via Bluetooth I2S

[PATCH 3/3] ARM: dts: sun7i: Add support for the Ainol AW1 tablet

[Paul Kocialkowski]

This adds support for the Ainol AW1, an A20-based 7" tablet from Ainol.

The following board-specific features are supported:
* LCD panel
* Backlight
* USB OTG
* Buttons
* Touchscreen (doesn't work without non-free firmware)
* Accelerometer
* Battery

The following are untested:
* Audio output
* Audio speakers
* USB via SPCI connector

The following are not supported:
* Wi-Fi
* Bluetooth
* NAND
* Audio via SPCI connector
* Audio via Bluetooth I2S

Mhh, looks like this should be lcd0_rgb666_pins.

I point you to this Thread and back:
https://lists.freedesktop.org/archives/dri-devel/2018-March/170688.html

I did the same for rgb888, so good part is discussed.

IMHO I would:
- call lcd0_rgb666_pins, since this is for LCD0 interface
- same as above, call lcd0-rgb666, take care about using "-" instad of 
"_" that can cause DTC warnings.
- remove @0 since only this set can achieve LCD0 RGB666, and I
   don't think there will be other combinations.

Kind regards

[PATCH 2/3] ARM: dts: sun7i: Add RGB666 pins definition

[Paul Kocialkowski]

This adds the pins definition for RGB666 LCD panels on the A20. It was
imported from the A33 definition, that concernes the same set of pins.
