[PATCH 0/3] ARM: dts: sun5i: hsg-h702: Enable USB OTG and LRADC keys

[Chen-Yu Tsai]

Hi Maxime,

This series enables USB OTG and the volume buttons on the side of
the HSG-H702 tablet.

The third patch is just for reference, as the axp209 usb power supply
driver hasn't been merged yet.


Regards
ChenYu

Sorry, please ignore. Something bad happened when I split the patches.

PEBCAK .. The series doesn't compile because of the last patch.

Anyway, since you had some comments on the patches Hans posted, I'll
fix up the same issues in mine as well.
