Things are little complicated here :-). Currently qcom,echi-host is
supposed to control host role. Not tested this completely, but this how
is handled also by down stream kernel ( In this
repo there are even 2 slightly different versions of the driver.

And OTG and PHY control situations is even ... Currently this
functionality is handled by phy-msm-usb. There is a separate gadget
driver downstream, which seems to be used in production targets.

My plan is to first port minimal set of changes form downstream kernel
to phy-msm-usb, which will bring up peripheral role.
