[PATCH 3/3] dts: arm64: sunxi: add initial dts for T95 AXP313 tv box

From: Kamil Kasperski
Date: Mon Mar 11 2024 - 13:49:00 EST


T95 is a most commonly known for being a box with a pre-installed malware.
It uses Allwinner H616 and comes with eMMC and DDR3 memory.

Those TV boxes usually come with common hardware:
- Allwinner H616 SoC
- 2/4 GB DDR3 SDRAM (Hynix H5TQ2G43BFR)
- 16/32/64 GB eMMC
- microSD slot
- AXP305 or AXP313 PMIC depending on board revision
- 3.5mm A/V output
- HDMI port
- 2x USB 2.0 ports
- 100M ETH using Internal PHY
- 7-segment display
- DC 5V barrel jack port

The board contains holes hor UART header wired to &uart0.
>From the DRAM specification its operation voltage is 1.5V.
