Hi, The Lctech Pi F1C200s is a small development board with the eponymous Allwinner SoC. It ships with SPI NAND flash, but I couldn't get that to work: ============ spi-nand spi0.0: unknown raw ID 00000000 spi-nand: probe of spi0.0 failed with error -524 ============ I leave in the DT node anyway (minus partitions), matching the schematic. The boards has two USB-C ports, one of which is connected to a USB serial adapter chip. Since the other one (connected to the MUSB controller) lacks any CC pin connections, I need to fix the OTG role here, and went with peripheral. Forcing host mode worked as well, but requires a separate power supply (although the other USB port works for that as well). The board was apparently also sold under the "Cherry Pi" brand before. Patches 1 and 2 add the required DT bindings for the vendor and board name strings, patch 3 adds the .dts file. Please have a look!
