#1367053 — [PATCH v6 0/3] usb: otg-fsm: Add documentation and some trivial cleanups

Hi,

Add documentation for struct otg_fsm with some trivial cleanups.
All patches have been Acked by otg-fsm maintainer (Peter Chen).

cheers,
-roger

#1367054 — [PATCH v6 3/3] usb: otg-fsm: Prevent build warning "VDBG" redefined

If usb/otg-fsm.h and usb/composite.h are included together
then it results in the build warning [1].

Prevent that by using dev_vdbg() instead.

Also get rid of MPC_LOC which doesn't seem to be used
by anyone.

#1367059 — [PATCH v6 1/3] usb: otg-fsm: Add documentation for struct otg_fsm

struct otg_fsm is the interface to the OTG state machine.

Document the input, output and internal state variables.
Definations are taken from Table 7-2 and Table 7-4 of
the USB OTG & EH Specification Rev.2.0

Re-arrange some of the members as per use case for more
clarity.

Patch 3 might cause a build failure for drivers/usb/phy/phy-fsl-usb.c

I will send a revised patch 3 that locally defines VDBG for phy-fsl-usb.c
