Hi, You're right on that these pins aren't currently in use by any .dts file, but the manufacturer, Sinovoip, should be submitting a .dts file for the board soon, and if they don't, I'm sure the Linux-Sunxi community will do. You can see a work-in-progress device tree at: https://github.com/BPI-SINOVOIP/BPI-Mainline-kernel/blob/master/arch/arm/boot/dts/sun6i-a31s-bananapi-m2.dts Apologies in advance if some of what I've written is against any rule, I read them, but something might be wrong because this is my first attempt to submit a patch. Cheers, Luis Araneda.
