| * MIPS: Alchemy: abstract USB block control register accessManuel Lauss2011-10-241-99/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Alchemy chips have one or more registers which control access to the usb blocks as well as PHY configuration. I don't want the OHCI/EHCI glues to know about the different registers and bits; new code hides the gory details of USB configuration from them.

* USB: automatically enable RHSC interruptsAlan Stern2008-08-211-1/+0
| | | | | | | | | | | | | | | | | This patch (as1069c) changes the way OHCI root-hub status-change interrupts are enabled. Currently a special HCD method, hub_irq_enable(), is called when the hub driver is finished using a root hub. This approach turns out to be subject to races, resulting in unnecessary polling. The patch does away with the method entirely. Instead, the driver automatically enables the RHSC interrupt when no more status changes are present. This scheme is safe with controllers using level-triggered semantics for their interrupt flags.

* Revert "USB: don't explicitly reenable root-hub status interrupts"Linus Torvalds2008-07-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | This reverts commit e872154921a6b5256a3c412dd69158ac0b135176. Andrey Borzenkov reports that it resulted in a totally hung machine for him when loading the OHCI driver. Extensive netconsole capture with SysRq output shows that modprobe gets stuck in ohci_hub_status_data() when probing and enabling the OHCI controller, see for example http://lkml.org/lkml/2008/7/5/236 for an analysis. The problem appears to be an interrupt flood triggered by the commit that gets reverted, and Andrey confirmed that the revert makes things work for him again.

* ohci: Rework bus glue integration to allow several at onceSylvain Munaut2007-02-071-16/+0
| | | | | | | | | | | | | | | | | The previous model had the module_init & module_exit function in the bus glue .c files themselves. That's a problem if several glues need to be selected at once and the driver is built has module. This case is quite common in embedded system where you want to handle both the integrated ohci controller and some extra controller on PCI. The ohci-hcd.c file now provide the module_init & module_exit and appropriate driver registering/unregistering is done conditionally, using #ifdefs.

* USB: Properly unregister reboot notifier in case of failure in ehci hcdAleksey Gorelov2006-09-271-0/+2
| | | | | | | | | | | | | | | | | | | | | | If some problem occurs during ehci startup, for instance, request_irq fails, echi hcd driver tries it best to cleanup, but fails to unregister reboot notifier, which in turn leads to crash on reboot/poweroff. The following patch resolves this problem by not using reboot notifiers anymore, but instead making ehci/ohci driver get its own shutdown method. For PCI, it is done through pci glue, for everything else through platform driver glue. One downside: sa1111 does not use platform driver stuff, and does not have its own shutdown hook, so no 'shutdown' is called for it now. I'm not sure if it is really necessary on that platform, though.

* USB: OHCI avoids root hub timer pollingDavid Brownell2006-09-271-4/+1
| | | | | | | | | | | | | | This teaches OHCI to use the root hub status change (RHSC) IRQ, bypassing root hub timers most of the time and switching over to the "new" root hub polling scheme. It's complicated by the fact that implementations of OHCI trigger and ack that IRQ differently (the spec is vague there). Avoiding root hub timers helps mechanisms like "dynamic tick" leave the CPU in lowpower modes for longer intervals.

* [PATCH] USB: au1200: EHCI and OHCI fixesDaniel Mack2006-07-121-0/+1
| | | | | | | | | | | | | | | | | | | | I received an DBAU1200 eval kit from AMD a few days ago and tried to enable the USB2 port, but the current linux-2.6 GIT did not even compile with CONFIG_SOC_1200, CONFIG_SOC_AU1X00, CONFIG_USB_EHCI and CONFIG_USB_OHCI set. Furthermore, in ehci-hcd.c, platform_driver_register() was called with an improper argument of type 'struct device_driver *' which of course ended up in a kernel oops. How could that ever have worked on your machines? Anyway, here's a trivial patch that makes the USB subsystem working on my board for both OHCI and EHCI. It also removes the /* FIXME use "struct platform_driver" */.

* [PATCH] USB: Rename hcd->hub_suspend to hcd->bus_suspendAlan Stern2005-10-281-2/+2
| | | | | | | | | | | | | | | | This patch (as580) is perhaps the only result from the long discussion I had with David about his changes to the root-hub suspend/resume code. It renames the hub_suspend and hub_resume methods in struct usb_hcd to bus_suspend and bus_resume. These are more descriptive names, since the methods really do suspend or resume an entire USB bus, and less likely to be confused with the hub_suspend and hub_resume routines in hub.c. It also takes David's advice about removing the layer of bus glue, where those methods are called. And it implements a related change that David made to the other HCDs but forgot to put into dummy_hcd.

* [PATCH] all HCDs provide root hub suspend/resume methodsDavid Brownell2005-10-281-0/+5
| | | | | | | | | | | | | | | | | | | | | This cleans up a small recent FIXME, ensuring that all the HCDs provide root hub suspend/resume methods. It also wraps the calls to those root suspend routines just like on the PCI "USB_SUSPEND not defined" cases, so non-PCI bus glue won't be as tempted to behave very differently. Several of the SOC based OHCI drivers forgot to list those methods; the patch also adds those missing declarations.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+284
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
