As Maxime mentioned the other day [1]:
arch/arm/Kconfig:
config ARCH_SUNXI
	....
	select DM_KEYBOARD
	....
        select USB_KEYBOARD if DISTRO_DEFAULTS
Kconfig:
config DISTRO_DEFAULTS
        default y if ARCH_SUNXI || TEGRA

That is weird. Are you sure the USB port you connected the keyboard to
actually works? I found this to be a problem on some boards, due to
missing regulator support. I think I used the lower port on the Pine64
and that worked fine.

Cheers,
Andre.
