Description of problem:
BananaPi is an Allwinner A20/sunxi device.

The USB host controller is broken with kernel 4.6.3. I ehci-platform is loaded but I can't find any evidence the hardware's being activated, and nothing actually works on the USB ports.

Works fine with 4.5.7.

FAULTY:  kernel-4.6.3-300.fc24.armv7hl
WORKING: kernel-4.5.7-300.fc24.armv7hl

Attached are dmesgs from both kernels.

Comment 2 Clive Messer 2016-07-18 23:33:47 UTC 
Any progress on this?
Comment 3 Clive Messer 2016-07-19 17:58:23 UTC 
The culprit would seem to be....

-CONFIG_MFD_AXP20X=y
+CONFIG_MFD_AXP20X=m
+CONFIG_MFD_AXP20X_I2C=m
+CONFIG_MFD_AXP20X_RSB=m

ie. the axp20x module needs to be "force" loaded, as it is not auto loaded and isn't built into kernel anymore. (Well, actually the axp20x-i2c module, as that seems to be where the AXP209 is recognised. (It looks like the axp20x driver has had the I2C component, split into a separate module since 4.5 series kernels.)

For now I just added an /etc/dracut.conf.d/banana.conf

with contents....
force_drivers+="axp20x_i2c"
..... and rebuilt 4.6.4 initramfs from a working 4.5.7 kernel. 

Which had gotten my BananaPi's and Pro's back onto the network using USB wi-fi, now that USB is functional again.
Comment 4 James 2016-07-20 05:57:50 UTC 
I confirm that workaround works.
Comment 5 Peter Robinson 2016-09-08 09:46:52 UTC 
Thanks Clive, will take a look shortly.
Comment 6 Filip Bartmann 2016-10-12 09:57:27 UTC 
I have this problem on Banana Pi R1 with Fedora 25 Beta too. Is there any way to make it work with Fedora 25?

can you test the 4.8.2 kernel and let me know if that works?

Working with 4.8.2-300.fc25 on the Banana Pi.
Comment 9 Peter Robinson 2016-10-19 09:41:02 UTC 
So I've pushed the config changes to F24/23 so it'll be in the next kernel post 4.7.8 (likely 4.8.x) for those releases and 4.8.2-300.fc25 for F-25
