The BananaPi M4 Berry is a development board using the Allwinner H618
SoC. It comes with the following specs:
- Allwinner H618 SoC (4 * Arm Cortex-A53 cores, 1MB L2 cache)
- 2 GiB LPDDR4 DRAM
- 8 GiB eMMC flash
- AXP313a PMIC
- Gigabit Ethernet, using RTL8211 PHY
- RTL8821CU USB WiFi chip
- HDMI port
- 4 * USB 2.0 ports, via an on-board hub chip
- microSD card slot
- 3.5mm A/V port
- power supply and USB-OTG via USB-C connector
Add a devicetree file describing the components that we already have
bindings for, that excludes audio and video at the moment.
