* USB: EHCI: make ehci_read_frame_index platform independentAlan Stern2012-10-24
| | | | | | | | | | | | | | | | In preparation for splitting the ehci-hcd driver into a core library and separate platform-specific driver modules, this patch (as1617) changes the way ehci_read_frame_index() is handled. Since the same core library will have to work with both PCI and non-PCI platforms, the quirk handler routine will be compiled unconditionally. The decision about whether to call it or simply to read the frame index register is made at run time, based on whether the frame_index_bug quirk flag is set.

| | | | | | | | | | | In preparation for splitting the ehci-hcd driver into a core library and separate platform-specific driver modules, this patch (as1616) moves the console logging macros from ehci-dbg.c to ehci.h, where they will be available to the platform drivers.

* USB: EHCI: add condition for delay during the resumePeter Chen2012-10-24
| | | | | | | | | | | | | | | | Without this condition, all controllers will do this delay, and increase the resume time. Only enabled and unsuspended port needs this delay, but Some buggy hardware(like Synopsys usb controller) will clear suspend bit once they receive/send resume signal, so it takes resume bit as consideration. Tested it at Freescale i.mx6q Sabrelite board.

* USB: OHCI: make ohci-platform use devm_request_and_ioremap helperFlorian Fainelli2012-10-22
| | | | | | | | | | | | | | This patch changes the ohci-platform driver to use the device managed helper function for requesting memory region and ioremapping memory resources. As a result the error path in the probe function is simplified, and the platform driver remove callback does no longer need to release and iounmap memory resources. devm_request_and_ioremap() will use either the ioremap() or ioremap_nocache() handler depending on the resource's CACHEABLE flag, so we are good with this change.

As a result, all the common logic to handle USB present in drivers/usb/host/alchemy-common.c has no reason to remain here, so we move it to arch/mips/alchemy/common/usb.c which is a more appropriate place.
