From: Icenowy Zheng <uwu@xxxxxxxxxx> PopStick is a minimal Allwinner F1C200s dongle, with its USB controller wired to a USB Type-A plug, 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.
