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

Le mardi 10 avril 2018 à 23:31 +0200, Paul Kocialkowski a écrit :

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

This version didn't use the dedicated binding for the panel and will be fixed in v2 and onwards.

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
