Commit Message

Jisheng Zhang Feb. 11, 2024, 8:17 a.m. UTC 
The Sipeed Longan SoM 3H is a system on module based on the Allwinner
H618 SoC. The SoM features:

- Four ARM Cortex-A53 cores, Mali-G31 MP2 GPU
- 2/4 GiB LPDDR4 DRAM SoMs
- AXP313a PMIC
- eMMC

The Sipeed Longan PI 3H is a development board based on the above SoM.
The board features:
- Longan SoM 3H
- Raspberry-Pi-1 compatible GPIO header
- 2 USB 2.0 host port
- 1 USB 2.0 type C port (power supply + OTG)
- MicroSD slot
- 1Gbps Ethernet port (via RTL8211 PHY)
- HDMI port
- WiFi/BT chip

Add the devicetree file describing the currently supported features,
namely PMIC, LEDs, UART, SD card, eMMC, USB and Ethernet.

Hi Jisheng,

thanks for the changes, and for spotting the 5V/3.3V issue yourself,
which I missed. This looks good to me now.
