* | | | USB: EHCI: remove ehci_port_power() routineAlan Stern2012-10-3116-106/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | | | USB: EHCI: remove unused Link Power Management codeAlan Stern2012-10-317-239/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | | xhci: Fix missing break in xhci_evaluate_context_result.Sarah Sharp2012-10-251-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| * | | xhci: Fix potential NULL ptr deref in command cancellation.Sarah Sharp2012-10-251-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch modifies the ohci platform driver to accept the num_ports parameter to be set via platform_data. Setting the number of ports must be done after the call to ohci_hcd_init().

* | | USB: EHCI: add no_io_watchdog platform_data parameter to ehci-platformFlorian Fainelli2012-10-221-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Enhance the ehci-platform driver to also accept no_io_watchdog as a platform data parameter. When no_io_watchdog is set to 1, the ehci controller will set ehci->need_io_watchdog to 0. Since most EHCI controllers do need the I/O watchdog to be on, only let those which need it to turn the watchdog off. Make sure that we change need_io_watchdog after the call to ehci_setup() because ehci_setup() will unconditionnaly set need_io_watchdog to 1.

* | | OHCI: implement new semantics for URB_ISO_ASAPAlan Stern2012-10-222-6/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1614) updates the isochronous scheduling in ohci-hcd to match the new semantics for URB_ISO_ASAP. Testing revealed a hardware bug in the way my OHCI controller handles expired isochronous TDs; consequently the patch tries hard to avoid creating them (unlike the ehci-hcd and uhci-hcd drivers).
