[PATCH V4 0/6] USB: OHCI: more bus glues as separate modules

[Manjunath Goudar]

These patches are for separating the SOC On-Chip ohci host controller
from ohci-hcd host code into its own driver module.
This work is part of enabling multi-platform kernels on ARM;
it would be nice to have in 3.12.

V2:
  In patch 5/6 and 6/6:
  -Set non-standard fields in hc_driver manually, rather than
   relying on an expanded struct ohci_driver_overrides.
  -Save orig_ohci_hub_control and orig_ohci_hub_status_data rather than
   relying on ohci_hub_control and hub_status_data being exported.

  In patch 1/6 to 4/6
  -ohci_setup() has been removed because it is called in .reset member
   of the ohci_hc_driver structure.

V3:
 In patch 5/6 and 6/6:
 -ohci_setup() has been removed because it is called in .reset member
  of the ohci_hc_driver structure.

 In patch 5/6:
 -The ohci_restart() function is not required in  current scenario,
  only discarding connection state of integrated transceivers is sufficient,
  for this directly handling ohci->hc_control.

 In patch 2/6 :
 -rewritten if (config->otg || config->rwc) block statements into
  two separate 'if blocks' to handle below scenarios
  1. config->otg set scenario.
  2. if any of these (config->otg, config->rwc) are set, this
     scenario should be handled only after ohci_setup()
 
 In patch 1/6 and 4/6:
  No change.

V4:
 In patch 1/6 and 4/6:
  No change.

 In patch 2/6 :
 -usb_remove_hcd() function is required a valid clock that is what
  omap_ohci_clock_power(0) is called after hcd shutdown.

 In patch 3/6 :
 -V3 modification revert back, only ohci->regs setting write()
  function has been removed because ohci->regs doesn't get set until
  usb_add_hcd.

 In patch 5/6 :
 - Removed extra space after "tristate".
 - Removed extra space between function name  and '(' characters.
 - MODULE_ALIAS line moved to last statement of ohci-at91 file.

 In patch 6/6 :
 - Removed extra space before the '='.
 - Moved  /* forward definitions */ line before the declarations of functions.

Manjunath Goudar (6):
