IIRC the policy we have is only add stuff that is actually used. I don't
see a follow up patch using these in any boards.

Also, please Cc LAKML for DT patches.

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.

Hans already submitted one. See:
