ARM devicetrees were moved into subdirectories, so this patch will need
to be rebased.

axp209.dtsi is already included by sunxi-itead-core-common.dtsi. You
don't need to include it again here.

Extra blank line here and above otg_sram.

The mini-USB port is always powered, and the ID pin isn't hooked up in a
usable way, so this should be "host".

The board's power supply is only connected to the ACIN pins of the
AXP209, not the USBVBUS pin (which is pulled to 3.3V for some reason).
So usb_power_supply should not be enabled or used below.

The ID pin is connected to N_VBUSEN on the PMIC, not this GPIO. Per the
schematic, this GPIO is not connected to anything.

Per the schematic, this GPIO is not connected to anything.

As explained above, please remove this property.
