Sunxi kernel 4.9 usb not working

On banana pi latest snapshot USB not working.
Reason is not setting CONFIG_MFD_AXP20X_I2C

Pls fix !

Is this a new symbol? I took a quick look at the change history of the sunxi target and couldn't spot this symbol in the previous config-4.4.

Yes it looks like its not present in 4.4.
When enabled usb works

Thanks for the heads-up @bolvan - I committed the missing symbol with;a=commitdiff;h=f66fe0080abe322d949a5b44a47fc36cbb28d9e7.

I found the hint here :

I have filled a bug and also wrote here, but no one picked it, glad that someone implemented it
The reason comes from refactoring of AXP20X driver, they have decoupled the DRIVER from the BUS code
