Hey Hans,
I've tried getting your musb stuff working on a cubietruck, but i
don't seem to see this patch on your linux-sunxi/sunxi-wip branch on
github? Is your github branch fully functional at the moment?
What I have done so far, is build the kernel using sunxi_defconfig
and enabled USB_MUSB_SUNXI with its dependancies (musb isn't enabled
there by default): USB_SUPPORT [=y] && USB_MUSB_HDRC [=y] &&
ARCH_SUNXI [=y] && NOP_USB_XCEIV [=y] && PHY_SUN4I_USB [=y] && EXTCON
[=y] && GENERIC_PHY [=y] Selects: SUNXI_SRAM [=y]
I changed the dts from dr_mode='otg' to dr_mode='host', a) we only
need host mode anyway (the id pin isn't properly connected)
If you change the dr_mode to host then you _must_ also remove any
id_det and vbus_det
gpio settings from the usb_phy node in the dts, as the sun4i phy code
detects
host vs otg mode by checking for the presence of these.
Yes, this fixes it and makes it work. Thanks.
Also I apologize for not noticing this patch in your queue before :)
Looks like everything is all ready in your WIP branch.
Now, I see that Chen-Yu found the same problems here:

So far, with your mentioned changes to remove the id and vbus gpio's you
can have my

quick and easy way.
Dmesg produces the following related to musb.

The usb_phy_generic missing shouldn't be too bad? But the usb0-vbus
being disabled obviously might be related to the musb port not working?
Correct.
For starters I would try the dts changes I suggested above.
Yep that fixed it.

Hans
