2012-11-11USB: EHCI: miscellaneous cleanups for the library conversionAlan Stern
This patch (as1630) cleans up a few minor items resulting from the split-up of the ehci-hcd driver: Remove the product_desc string from the ehci_driver_overrides structure. All drivers will use the generic "EHCI Host Controller" string. (This was requested by Felipe Balbi.) Allow drivers to pass a NULL pointer to ehci_init_driver() if they don't have to override any settings. Remove a #define symbol that is no longer used from the ChipIdea host driver. Rename overrides to pci_overrides in ehci-pci.c, for consistency with ehci-platform.c. Mark the *_overrides structures as __initdata.

2012-11-02USB: EHCI: fix build error by making ChipIdea host a normal EHCI driverAlan Stern
This patch (as1627) splits the ehci-hcd core code, which has become a separate library module, out from the ChipIdea host driver. Instead of #include-ing ehci-hcd.c directly, the ChipIdea module will now use the ehci-hcd library in a normal fashion. This fixes a build error caused by commit 3e0232039967d7a1a06c013d097458b4d5892af1 (USB: EHCI: prepare to make ehci-hcd a library module); I had forgotten about the unorthodox way the ChipIdea driver uses the ehci-hcd code.

2012-11-02USB: ohci-exynos: initialize registers pointer earlierVincent Palatin
In the former code, we have a race condition between the first interrupt and the regs field initilization in the usb_hcd structure. If the OHCI irq fires before hcd->regs is set, we are getting a null pointer dereference in ohci_irq. When calling usb_add_hcd(), it first executes the reset() callback, then enables the ohci interrupt, and finally executes the start() callback. So moving the ohci_init() call which actually initializes the reg field from start() to reset() should remove the race. Tested by enabling the external HSIC hub in the bootloader on an exynos5 machine and booting. With the former code, this triggers an early interrupt about 50% of the boots and a subsequent kernel panic in ohci_irq when trying to access the registers.

2012-11-01USB: EHCI: prepare to make ehci-hcd a library moduleAlan Stern
This patch (as1624) prepares ehci-hcd for being split up into a core library and separate platform driver modules. A generic ehci_hc_driver structure is created, containing all the "standard" values, and a new mechanism is added whereby a driver module can specify a set of overrides to those values. In addition the ehci_setup(), ehci_suspend(), and ehci_resume() routines need to be EXPORTed for use by the drivers. As a side effect of this change, a few routines no longer need to be marked __maybe_unused.

2012-10-31USB: EHCI: remove ehci_port_power() routineAlan Stern
This patch (as1623) removes the ehci_port_power() routine and all the places that call it. There's no reason for ehci-hcd to change the port power settings; the hub driver takes care of all that stuff. There is one exception: When the controller is resumed from hibernation or following a loss of power, the ports that are supposed to be handed over to a companion controller must be powered on first. Otherwise the handover won't work. This process is not visible to the hub driver, so it has to be handled in ehci-hcd.

2012-10-31USB: EHCI: remove unused Link Power Management codeAlan Stern
This patch (as1622) removes the USB-2.1 Link Power Management code from the ehci-hcd driver. This code was never integrated with usbcore, it is full of bugs, and it was not getting used by anybody. However, the debugging code for dumping the LPM-related fields in the EHCI registers is left in place. In theory it might be useful to see these values, even though we don't use them. This essentially amounts to a partial revert of commit aa4d8342988d0c1a79ff19b2ede1e81dfbb16ea5 (USB: EHCI: EHCI 1.1 addendum: preparation) and an almost full revert of commit 48f24970144479c29b8cee6d2e1dbedf6dcf9cfb (USB: EHCI: EHCI 1.1 addendum: Basic LPM feature support) plus its follow-ons.

2012-10-25xhci: Fix missing break in xhci_evaluate_context_result.Sarah Sharp
Coverity complains that xhci_evaluate_context_result() is missing a break statement after the COMP_EBADSLT switch case. It's not a big deal, since we wanted to return the same error code as the case statement below it does. The end result would be one that a Slot Disabled error completion code would also print the warning message associated with a Context State error code. No other bad behavior would result. It's not worth backporting to stable kernels, since it only fixes an issue with too much debugging. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>
2012-10-25xhci: Fix potential NULL ptr deref in command cancellation.Sarah Sharp
The command cancellation code doesn't check whether find_trb_seg() couldn't find the segment that contains the TRB to be canceled. This could cause a NULL pointer deference later in the function when next_trb is called. It's unlikely to happen unless something is wrong with the command ring pointers, so add some debugging in case it happens. This patch should be backported to stable kernels as old as 3.0, that contain the commit b63f4053cc8aa22a98e3f9a97845afe6c15d0a0d "xHCI: handle command after aborting the command ring".

This patch (as1619) improves the interface to the "hub_for_each_child" macro. The name clearly suggests that the macro iterates over child devices; it does not suggest that the loop will also iterate over unnconnected ports. The patch changes the macro so that it will skip over unconnected ports and iterate only the actual child devices. The two existing call sites are updated to avoid testing for a NULL child pointer, which is now unnecessary.

2012-10-22USB: move common alchemy USB routines to arch/mips/alchemy/common.cFlorian Fainelli
A previous patch converted the Alchemy platform to use the OHCI and EHCI platform drivers. 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. This change was suggested by Manuel Lauss.
