> 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.

"make dtbs_check" is not happy with cells and partitions. Do we really need 
them? If yes, then binding needs to be updated beforehand.
