[PATCH V2] USB: EHCI: make ehci-w90X900 a separate driver
Separate the W90X900(W90P910) 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 W90X900(W90P910) can be booted with a multi-platform kernel and an ehci driver that only works on one of them. With the infrastructure added by Alan Stern in patch 3e0232039 "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 w90X900 bus glue. This patch is rebased on greghk/usb-next 3.12 rc1.

[PATCH V2] USB: EHCI: make ehci-w90X900 a separate driver
Separate the W90X900(W90P910) 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 W90X900(W90P910) can be booted with a multi-platform kernel and an ehci driver that only works on one of them. With the infrastructure added by Alan Stern in patch 3e0232039 "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 w90X900 bus glue.

This work is part of enabling multi-platform kernels on ARM; however, note that other changes are still needed before W90X900(W90P910) can be booted with a multi-platform kernel and an ehci driver that only works on one of them. With the infrastructure added by Alan Stern in patch 3e0232039 "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 w90X900 bus glue.

[PATCH V2] USB: EHCI: make ehci-w90X900 a separate driver
Separate the W90X900(W90P910) 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 W90X900(W90P910) can be booted with a multi-platform kernel and an ehci driver that only works on one of them. With the infrastructure added by Alan Stern in patch 3e0232039 "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 w90X900 bus glue.

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

Separate the OHCI NXP host controller driver from ohci-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. Many place function name and struct name started with usb, current scenario replaced usb with ohci for proper naming.

[PATCH] USB: EHCI: make ehci-w90X900 a separate driver
Separate the W90X900(W90P910) 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 W90X900(W90P910) can be booted with a multi-platform kernel and an ehci driver that only works on one of them. With the infrastructure added by Alan Stern in patch 3e0232039 "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 w90X900 bus glue.

[PATCH V4 11/11] USB: OHCI: Properly handle ohci-spear suspend
Suspend scenario in case of ohci-spear glue was not properly handled as it was not suspending generic part of ohci controller. Calling explicitly the ohci_suspend() routine in spear_ohci_hcd_drv_suspend() will ensure proper handling of suspend scenario.
