Subject: [RFC PATCH 3/9] arm64: dts: meson: add initial device-trees for X96-AIR
Date:   Tue, 30 Nov 2021 06:05:17 +0000

The Amediatek X96-AIR is based on Amlogic S905X3 reference board
designs and ships in multiple configurations:

– 4GB DDR3 + 64GB eMMC + WiFi a/b/g/n/ac + BT + Gb Ethernet
– 4GB DDR3 + 32GB eMMC + WiFi a/b/g/n/ac + BT + Gb Ethernet
– 4GB DDR3 + 32GB eMMC + WiFi b/g/n (no BT) + 10/100 Ethernet
– 2GB DDR3 + 16GB eMMC + WiFi b/g/n (no BT) + 10/100 Ethernet
...
- HDMI 2.1 video
- S/PDIF optical output
- AV output
- 2x USB 2.0 inc. OTG port
- 1x USB 3.0 port
- IR receiver
- 1x micro SD card slot (internal)
- 1x Reset/Update button (in AV jack)
- 7-segment VFD

The device-tree with -100 suffix supports models with 10/100 Ethernet
and with -1000 suffix supports models with Gigabit Ethernet.
