* | USB: EHCI: improvements to unlink_empty_async_suspended()Alan Stern2016-02-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | unlink_empty_async_suspended() is marked __maybe_unused. This is because its caller, ehci_bus_suspend(), is protected by "#ifdef CONFIG_PM". We should use the same protection here instead of __maybe_unused. unlink_empty_async_suspended() gets called only when the root hub is suspended. It's silly for it to call start_iaa_cycle() at such a time; the IAA mechanism doesn't work when the root hub isn't running. It should call end_unlink_async() instead. But even this isn't necessary, since there already is a call to end_iaa_cycle() right before the call to unlink_empty_async_suspended(). All we have to do is interchange the two subroutine calls.

* | USB: EHCI: add a delay when unlinking an active QHAlan Stern2016-02-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Michael Reutman reports that an AMD/ATI EHCI host controller on one of his computers does not stop transferring data when an active bulk QH is unlinked from the async schedule. Apparently that host controller fails to implement the IAA mechanism correctly when an active QH is unlinked. This leads to data corruption, because the controller continues to update the QH in memory when the driver doesn't expect it. As a result, the next URB submitted for that QH can hang, because the link pointers for the TD queue have been messed up. This misbehavior is observed quite regularly. To be fair, the EHCI spec (section 4.8.2) says that active QHs should not be unlinked. It goes on to recommend a procedure that involves waiting for the QH to go inactive before unlinking it. In the real world this is impractical, not least because the QH may _never_ go inactive. (What were they thinking?) Sometimes we have no choice but to unlink an active QH. In an attempt to avoid the problems that can ensue, this patch changes how the driver decides when the unlink is complete. In addition to waiting through two IAA cycles, in cases where the QH was not known to be inactive beforehand we now wait until a 2-ms period has elapsed with the host controller making no change to the QH data structure (the hw_current and hw_token fields in particular). The intuition here is that after such a long period, the endpoint must be NAKing and hopefully the QH has been dropped from the host controller's internal cache. There's no way to know if this reasoning is really valid -- the spec is no help in this regard -- but at least this approach fixes Michael's problem. The test for whether the QH is already known to be inactive involves the reason for unlinking the QH originally. If it was unlinked because it had halted, or it stopped in response to a short read, or it overlaid a dummy TD (a silicon bug), then it certainly is inactive. If it was unlinked because the TD queue was empty and no TDs have been added to the queue in the meantime, then it must be inactive. Or if the hardware status indicates that the QH is currently halted (even if that wasn't the reason for unlinking it), then it is inactive. Otherwise, if none of those checks apply, we go through the 2-ms delay.

* | USB: EHCI: improve handling of the ehci->iaa_in_progress flagAlan Stern2016-02-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch improves the way ehci-hcd handles the iaa_in_progress flag. The current code is somewhat careless in this regard: The flag is meaningless when the root hub isn't running, most particularly after the root hub has been suspended. But in start_iaa_cycle(), the driver checks the flag before checking the root hub's state. They should be checked in the opposite order. That routine also sets the flag too early, before it has definitely committed to starting an IAA cycle. The flag is turned off in end_unlink_async(). Upcoming changes will call that routine at other times, not just at the end of an IAA cycle. The two actions are logically separate (although related), so we separate out a new routine to be called in place of end_unlink_async() whenever an IAA cycle ends: end_iaa_cycle(). iaa_in_progress should be turned off when the root hub is suspended -- we certainly don't want it still to be set when the root hub resumes. Therefore the call to end_unlink_async() in ehci_bus_suspend() should also be replaced with a call to end_iaa_cycle().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The default value for the 'transceiver select' field of the PORTSC register may not always be correct. Previously the phy-msm-usb driver would do this for us, but since ehci-msm can now be instantiated standalone without any PHY driver, the register needs to be explicitly initialized to ULPI mode to properly communicate with the PHY. This is not readily apparent, as firmware or bootloader code also happen to pre-initialize this for us. However, it can manifest when performing a driver unbind/rebind as follows: cd /sys/bus/platform/drivers/msm_hsusb_host echo QCOM8040:00 > unbind echo QCOM8040:00 > bind The EHCI core executes a controller reset as part of this, and as a result the register in question would revert to its default state and must be re-initialized properly. Furthermore this may be useful in the future when adding PM suspend/resume support.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For historic reasons, the tegra platform selects USB_ULPI from architecture code, but that hasn't really made sense for a long time, as the only user of that code is the Tegra EHCI driver that has its own Kconfig symbol. This removes the 'select' statements from mach-tegra and drivers/soc/tegra and adds them with the device driver that actually needs them.
