Subject: [PATCH v2 0/2] usb: dwc2: Remove host and gadget only code from core

This series moves the host/gadget-specific code from core.c to hcd.c
and gadget.c so that they will be compiled only when their respective
configurations are selected, or in DRD.

This is mostly just a straight move of the code. I have also added
some comments to group related functions together.

Compiled and tested in all three modes.

This should also solve the issue reported here:
http://marc.info/?l=linux-usb&m=145591813410106&w=2

Although I wasn't able to test it... couldn't figure out how to
disable CONFIG_USB and enable DWC2 in gadget mode.

Felipe,

This should be applied after Doug's series on your testing/next
branch.

Regards,
John

v2:
* Addressed issues from Douglas Anderson
* Restored comments on dwc2_calc_frame_interval()
* Made some functions static and removed their prototypes from headers
