[PATCH v2 1/2] dt-bindings: arm: amlogic: add support for the WeTek Core 2

[Christian Hewitt]

The WeTek Core 2 is a commercial Android device based on the Amlogic Q200
reference design using the S912-H chipset. Specs:

3GB DDR3 RAM
32GB eMMC storage
10/100 Ethernet using Realtek RTL8152 (internal USB)
802.11 a/b/g/n/ac + BT 4.1 sdio wireless module (AP6356S)
2x single colour LEDs to indicate power
1x power button
1x reset button on the underside of the box
HDMI 2.0 (4k@60p) video
Composite video + 2-channel audio output on 3.5mm jack
S/PDIF audio output
2x USB 2.0 ports
1x USB OTG port (internal)
1x micro SD card slot
UART pins (internal)
IR Sensor

[PATCH v2 2/2] arm64: dts: meson: add support for the WeTek Core 2

[Christian Hewitt]

The WeTek Core2 is a commercial device based on the Amlogic Q200 reference
design but with the following differences:

- 3GB RAM, 32GB eMMC
- Blue and Red LEDs used to signal on/off status
- uart_AO can be accessed after opening the case; soldering required
- USB OTG is not accessible (inside the case)
- Realtek RTL8152 Ethernet (internal USB connection)
