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.
