The Libre Computer ALL-H3-IT board is a small single board computer that is roughly the same size as the Raspberry Pi Zero, or around 20% smaller than a credit card. The board features: - H2, H3, or H5 SoC from Allwinner - 2 DDR3 DRAM chips - Realtek RTL8821CU based WiFi module - 128 Mbit SPI-NOR flash - micro-SD card slot - micro HDMI video output - FPC connector for camera sensor module - generic Raspberri-Pi style 40 pin GPIO header - additional pin headers for extra USB host ports, ananlog audio and IR receiver Only H5 variant test samples were made available, but the vendor does have plans to include at least an H3 variant. Thus the device tree is split much like the ALL-H3-CC, with a common dtsi file for the board design, and separate dts files including the common board file and the SoC dtsi file. The other variants will be added as they are made available. The device tree was synced over from the Linux kernel, along with other H3/H5 changes, in a previous patch. Thus only the defconfig and an entry to the MAINTAINERS file is added.
