2011-10-28EHCI: fix direction handling for interrupt data togglesAlan Stern
commit e04f5f7e423018bcec84c11af2058cdce87816f3 upstream. This patch (as1480) fixes a rather obscure bug in ehci-hcd. The qh_update() routine needs to know the number and direction of the endpoint corresponding to its QH argument. The number can be taken directly from the QH data structure, but the direction isn't stored there. The direction is taken instead from the first qTD linked to the QH. However, it turns out that for interrupt transfers, qh_update() gets called before the qTDs are linked to the QH. As a result, qh_update() computes a bogus direction value, which messes up the endpoint toggle handling. Under the right combination of circumstances this causes usb_reset_endpoint() not to work correctly, which causes packets to be dropped and communications to fail. Now, it's silly for the QH structure not to have direct access to all the descriptor information for the corresponding endpoint. Ultimately it may get a pointer to the usb_host_endpoint structure; for now, adding a copy of the direction flag solves the immediate problem. This allows the Spyder2 color-calibration system (a low-speed USB device that sends all its interrupt data packets with the toggle set to 0 and hance requires constant use of usb_reset_endpoint) to work when connected through a high-speed hub. Thanks to Graeme Gill for supplying the hardware that allowed me to track down this bug.

2011-10-28EHCI: only power off port if over-current is activeSergei Shtylyov
commit 81463c1d707186adbbe534016cd1249edeab0dac upstream. MAX4967 USB power supply chip we use on our boards signals over-current when power is not enabled; once it's enabled, over-current signal returns to normal. That unfortunately caused the endless stream of "over-current change on port" messages. The EHCI root hub code reacts on every over-current signal change with powering off the port -- such change event is generated the moment the port power is enabled, so once enabled the power is immediately cut off. I think we should only cut off power when we're seeing the active over-current signal, so I'm adding such check to that code. I also think that the fact that we've cut off the port power should be reflected in the result of GetPortStatus request immediately, hence I'm adding a PORTSCn register readback after write...

2011-10-28USB: EHCI: go back to using the system clock for QH unlinksAlan Stern
commit 004c19682884d4f40000ce1ded53f4a1d0b18206 upstream. This patch (as1477) fixes a problem affecting a few types of EHCI controller. Contrary to what one might expect, these controllers automatically stop their internal frame counter when no ports are enabled. Since ehci-hcd currently relies on the frame counter for determining when it should unlink QHs from the async schedule, those controllers run into trouble: The frame counter stops and the QHs never get unlinked. Some systems have also experienced other problems traced back to commit b963801164618e25fbdc0cd452ce49c3628b46c8 (USB: ehci-hcd unlink speedups), which made the original switch from using the system clock to using the frame counter. It never became clear what the reason was for these problems, but evidently it is related to use of the frame counter. To fix all these problems, this patch more or less reverts that commit and goes back to using the system clock. But this can't be done cleanly because other changes have since been made to the scan_async() subroutine. One of these changes involved the tricky logic that tries to avoid rescanning QHs that have already been seen when the scanning loop is restarted, which happens whenever an URB is given back. Switching back to clock-based unlinks would make this logic even more complicated. Therefore the new code doesn't rescan the entire async list whenever a giveback occurs. Instead it rescans only the current QH and continues on from there. This requires the use of a separate pointer to keep track of the next QH to scan, since the current QH may be unlinked while the scanning is in progress. That new pointer must be global, so that it can be adjusted forward whenever the _next_ QH gets unlinked. (uhci-hcd uses this same trick.) Simplification of the scanning loop removes a level of indentation, which accounts for the size of the patch. The amount of code changed is relatively small, and it isn't exactly a reversion of the b963801164 commit. This fixes Bugzilla #32432.

2011-10-28USB: OHCI: fix another regression for NVIDIA controllersAlan Stern
commit 6ea12a04d295235ed67010a09fdea58c949e3eb0 upstream. The NVIDIA series of OHCI controllers continues to be troublesome. A few people using the MCP67 chipset have reported that even with the most recent kernels, the OHCI controller fails to handle new connections and spams the system log with "unable to enumerate USB port" messages. This is different from the other problems previously reported for NVIDIA OHCI controllers, although it is probably related. It turns out that the MCP67 controller does not like to be kept in the RESET state very long. After only a few seconds, it decides not to work any more. This patch (as1479) changes the PCI initialization quirk code so that NVIDIA controllers are switched into the SUSPEND state after 50 ms of RESET. With no interrupts enabled and all the downstream devices reset, and thus unable to send wakeup requests, this should be perfectly safe (even for non-NVIDIA hardware). The removal code in ohci-hcd hasn't been changed; it will still leave the controller in the RESET state. As a result, if someone unloads ohci-hcd and then reloads it, the controller won't work again until the system is rebooted. If anybody complains about this, the removal code can be updated similarly. This fixes Bugzilla #22052.
