Hi Hans,
This series fixes otg support on the A23 q8h tablets. It adds support
for the AXP's (AXP221/223 for now) VBUS detection function.
I've tested this with a USB wireless keyboard dongle, which works fine.
More importantly, I'm using this and your mainline kernel musb work plus
a few A23 dts patches to get musb working on my q8h tablet in host mode.
I have an ethernet dongle plugged in, which works reasonably well.
Note that U-Boot never calls musb_shutdown() to do proper cleanup, like
disabling VBUS, so the current state carries on into Linux.
Regards
ChenYu
