As mentioned in the other patch, if that is the case, I don't think we need to bother about the version number in the filename and compatible strings, especially if a v1.0 will never be upstreamed. If there are users of the internal version still, they can use an explicit "v1.0" in their downstream versions. So apart from what Krzysztof and Clement already mentioned, the DT itself looks fine to me otherwise. I also ran dt-validate on it, and used it as a base for another F1C200s board.

PopStick is a minimal Allwinner F1C200s dongle, with its USB controller wired to a USB Type-A port, a SD slot and a SPI NAND flash on board, and an on-board CH340 USB-UART converted connected to F1C200s's UART0. Add a device tree for it. As F1C200s is just F1C100s with a different DRAM chip co-packaged, directly use F1C100s DTSI here. This commit covers the v1.1 version of this board, which is now shipped. v1.0 is some internal sample that have not been shipped at all.
