This patch moves the part of code that initializes the PHY bus width.
This results in simpler code and removes the need to check whether

When the driver is removed s3c_hsotg_phy_disable is called three times
instead of once. This results in decreasing of the phy reference counter
below zero and thus consecutive inserts of the module fails.
This patch removes calls to s3c_hsotg_phy_disable from s3c_hsotg_remove

In the Generic PHY Framework a NULL phy is considered to be a valid phy
thus the "if (hsotg->phy)" check does not give us the information whether

In addition to the above this patch also removes phy_init from probe and
phy_exit from remove. T

Instead of building all of the xHCI code into a single module, separate
it out into the core (xhci-hcd), PCI (xhci-pci, now selected by the new
config option CONFIG_USB_XHCI_PCI), and platform (xhci-plat) drivers.
Also update the PCI/platform drivers with module descriptions/licenses
and have them
In preparation for allowing the xHCI host controller drivers to be built
as separate modules, export symbols from the xHCI core that may be used
by the host controller drivers.

Instead of calling xhci_compliance_mode_recovery_timer_quirk_check() again
in the PCI suspend path, just check for XHCI_COMP_MODE_QUIRK which will
have been set based on xhci_compliance_mode_recovery_timer_quirk_check()
in xhci_init().

Since the struct hc_driver is mostly the same across the xhci-pci,
xhci-plat, and the upcoming xhci-tegra driver, introduce the function
xhci_init_driver() which will populate the hc_driver with the default
xHCI operations. The caller must supply a setup function which will
be used as the hc_drive

It was suggested in the review of the Tegra xHCI driver [1] that we
allow xHCI drivers to be built as individual modules (like EHCI) instead
of building them all into the single xhci-hcd module as they are today.
Patches 1-3 prepare for making the xHCI PCI and platform drivers able
to be built as

I applied your two patches to current Fedora core 20 kernel sources, built,
remembered to remove the work-around boot-params and run grub2-mkconfig, and
rebooted. My Novatel GPS is recognized on plug-in to my USB2 ports and appears
to work correctly.

Set the default EP max packet value as 8 bytes, because in the case
of low-speed, 'ep_mps' is not set. Thus, the default value of 'ep_mps'
should be considered for the case of low-speed.
