arm64: dts: meson-g12a-tanix-tx5max: add initial device tree
Browse files Browse the repository at this point in the history 
The Tanix TX5 Max is based on the Amlogic U200 reference design
using the S905X2 chipset. Hardware specification:

- 4GB LPDDR4 RAM
- 32GB eMMC storage
- 10/100/1000 Base-T Ethernet using External RGMII PHY
- 802.11 a/b/g/b/ac + BT 4.1 sdio wireless
- HDMI 2.0 (4k@60p) video
- Composite video + 2-channel audio output on 3.5mm jack
- S/PDIF audio output
- 1x USB 3.0
- 1x USB 2.0
- 1x micro SD card slot
