2013-12-09usb: hcd: move controller wakeup setting initialization to individual driverPeter Chen1-1/+3
Individual controller driver has different requirement for wakeup setting, so move it from core to itself. In order to align with current etting the default wakeup setting is enabled (except for chipidea host). Pass compile test with below commands: make O=outout/all allmodconfig make -j$CPU_NUM O=outout/all drivers/usb Signed-off-by: Peter Chen <peter.chen@freescale.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2008-08-21USB: automatically enable RHSC interruptsAlan Stern1-1/+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.

2008-07-06Revert "USB: don't explicitly reenable root-hub status interrupts"Linus Torvalds1-0/+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.

2007-02-08ohci: Rework bus glue integration to allow several at onceSylvain Munaut1-16/+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.

2006-09-27USB: OHCI avoids root hub timer pollingDavid Brownell1-4/+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.

2005-10-29[PATCH] USB: Rename hcd->hub_suspend to hcd->bus_suspendAlan Stern1-2/+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.

2005-10-29[PATCH] all HCDs provide root hub suspend/resume methodsDavid Brownell1-0/+1
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.

2005-04-17Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+289
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!
