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.
