	xHCI misc cleanup patches for 3.10

	Hi Greg,

	Here's three cleanup patches for 3.10.  Nothing big here, just some debugging
	output changes, a macro rename, and a math macro change that should have no
	behavioral effects.

	Tested on the Intel Panther Point xHCI host, with USB storage and mouse, with
	xHCI debugging turned on.  I don't have the TI host that causes the debugging
	output changes to trigger.

      USB: EHCI: make ehci-msm a separate driver · 8c68e84f
      Manjunath Goudar authored 
      Separate the  Qualcomm QSD/MSM on-chip host controller driver from
ehci-hcd host code so that it can be built as a separate driver module.
This work is part of enabling multi-platform kernels on ARM;
however, note that other changes are still needed before Qualcomm QSD/MSM
can be booted with a multi-platform kernel, which is not expected before
3.11.

With the infrastructure added by Alan Stern in patch 3e023203
"USB: EHCI: prepare to make ehci-hcd a library module", we can
avoid this problem by turning a bus glue into a separate
module, as we do here for the msm bus glue.

In V5 (arnd):
 - add FIXME about missing usb_add_hcd() or usb_remove_hcd() calls

In V3:
 - Detailed commit message added here describing why this patch is required.
 - Arranged  #include's in alphabetical order.
 - driver.name initialized hcd_name[] = "ehci-msm" in platform_driver
   structure initialization instead of "msm-ehci", which was the reason
   why it broke in EHCI USB testing

In V2:
Tegra patch related changes removed from this patch.

      USB: EHCI: make ehci-atmel a separate driver · 97736961
      Manjunath Goudar authored 
      Separate the Atmel host controller driver from ehci-hcd host code
so that it can be built as a separate driver module.
This work is part of enabling multi-platform kernels on ARM;
however, note that other changes are still needed before Atmel can be
booted with a multi-platform kernel. This is currently planned for
Linux-3.11.

"USB: EHCI: prepare to make ehci-hcd a library module", we can
avoid this problem by turning a bus glue into a separate

In V4 (arnd):
 - reordered #include statements.
 - removed call to ehci_shutdown and the corresponding export

In V3:
 - Detailed commit message added here about why this patch is required.
 - Replaced hcd_name string "ehci-atmel" to "atmel-ehci".
 - Inserted blank line in the Makefile to separate the EHCI drivers from
   the following non-EHCI drivers.
 - Exported ehci_shutdown symbol as it is needed by the Atmel driver.
 - Eliminated ehci_atmel_setup routine because hcd registers
   can be directly set in the ehci_atmel_drv_probe function.

In V2:
  Resolved below compiler error.

host code so that it can be built as a separate driver module.
This work is part of enabling multi-platform kernels on ARM;

In V4 (arnd)
 - revert some of the pointless changes.
 - fix allocation of s5p specific data structure.

In V3:
 - Detailed commit message added here, why this patch is required.
 - MODULE_LICENSE is GPL v2.
 - Added .extra_priv_size to eliminate the separate allocation of
   the s5p_ehci_hcd structure and removed .reset function pointer
   initialization.
 - Arranged  #include's in alphabetical order.
 - After using extra_priv_size initialization, struct usb_hcd *hcd
   is redundant and can be removed from the probe function.
 - Eliminated s5p_ehci_phy_enable,contents of statements moved
   into the s5p_ehci_probe
 - Eliminated s5p_ehci_phy_disable, contents of statements moved into
   the s5p_ehci_remove.

      USB: EHCI: make ehci-spear a separate driver · 7675d6ba
      Manjunath Goudar authored 
      Separate the SPEAr host controller driver from ehci-hcd host code
so that it can be built as a separate driver module.
This work is part of enabling multi-platform kernels on ARM;
however, note that other changes are still needed before SPEAr can be
booted with a multi-platform kernel, but they are queued in the
arm-soc tree for 3.10.

With the infrastructure added by Alan Stern in patch 3e023203
"USB: EHCI: prepare to make ehci-hcd a library module", we can
avoid this problem by turning a bus glue into a separate
module, as we do here for the SPEAr bus glue.

In V4 (arnd):
 - renamed all 'struct spear_ehci' pointers from 'ehci' to the
   less ambiguous 'sehci'.
 - folded trivial spear_start_ehci/spear_stop_ehci functions into
   callers.
 - brought back initialization of ehci->caps.

In V3:
 - Detailed commit message added here about why this patch is required.
 - Eliminated ehci_spear_setup routine because hcd registers can
   be directly set in the spear_ehci_hcd_drv_probe function.
 - spear_overrides struct initialized.
 - Converted to using .extra_priv_size for allocating spear_ehci,
   and updated all users of that structure.
 - to_spear_ehci() macro modified for spear_ehci.

In V2:
 - Replaced spear as SPEAr everywhere, leaving functions/variables/config options.

      USB: EHCI: make ehci-orion a separate driver · a76dd463
      Manjunath Goudar authored 
      Separate the Orion host controller driver from ehci-hcd host
code into its own driver module because of following reason.

With the multiplatform changes in arm-soc tree, it becomes
possible to enable the mvebu platform (which uses
ehci-orion) at the same time as other platforms that require
a conflicting EHCI bus glue. At the moment, this results
in a warning like

drivers/usb/host/ehci-hcd.c:1297:0: warning: "PLATFORM_DRIVER" redefined [enabled by default]
drivers/usb/host/ehci-hcd.c:1277:0: note: this is the location of the previous definition
drivers/usb/host/ehci-orion.c:334:31: warning: 'ehci_orion_driver' defined but not used [-Wunused-variable]

and an ehci driver that only works on one of them.

With the infrastructure added by Alan Stern in patch 3e023203
"USB: EHCI: prepare to make ehci-hcd a library module", we can
avoid this problem by turning a bus glue into a separate
module, as we do here for the orion bus glue.

An earlier version of this patch was included in 3.9 but caused
a regression there, which has subsequently been fixed.

While we are here, use the opportunity to disabiguate the two
Marvell EHCI controller implementations in Kconfig.

In V4 (arnd):
- Improve Kconfig text

In V3:
- More detail provided in commit message regarding this patch.
- Replaced hcd_name string "ehci-orion" into "orion-ehci".
- MODULE_LICENSE is GPL v2.
- In ehci_init_driver calling second argument passed  as NULL instead of
  ehci_orion_overrides because ehci_orion_overrides is removed.

In V2:
- Tegra patch related changes removed from this patch.

      xhci - clarify compliance mode debug messages · 58b1d799
      Tony Camuso authored 
      There are no functional changes in this patch. However, because the
compliance mode timer can be deleted in more than one function, it
seemed expedient to include the function name in the debug strings.

Also limited the use of capitals to the first word in the compliance
mode debug messages, except after a function name where all words
start with lower case, in keeping with the style prevalent elsewhere
in xhci.c.
