The H-A133L board is an industrial development board made by Liontron. It contains a number of dedicated JST connectors, to connect external peripherals. It features: - Allwinner A133 SoC (4 * Arm Cortex-A53 cores at up to 1.6 GHz) - 1 GiB, 2 GiB or 4 GiB of LPDDR4 DRAM - between 16 and 128 GiB eMMC flash - AXP707 PMIC (compatible to AXP803) - 100 Mbit/s RJ45 Ethernet socket, using an JLSemi JL1101 PHY - XR829 WIFI+Bluetooth chip - 2 * USB 2.0 USB-A ports, plus three sets of USB pins on connectors (connected via a USB hub connected to USB1 on the SoC) - microSD card slot - 3.5mm A/V port - 12V power supply - connectors for an LVDS or MIPI-DSI panel Add the devicetree describing the board's peripherals and their connections. Despite being a devboard, the manufacturer does not publish a schematic (I asked), so the PMIC rail assignments were bases on BSP dumps, educated guesses and some experimentation. Dropping the always-on property from any of the rails carrying it will make the board hang as soon as the kernel turns off unused regulators.
