* ohci: Rework bus glue integration to allow several at onceSylvain Munaut2007-02-071-12/+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-s3c2410.c: clock now usb-bus-hostBen Dooks2006-09-271-1/+1
| | | | | | | | | | | | | | | | | | | | With the newer Samsung S3C2412 and S3C2413 SoC devices, the 48MHz USB clock has been given an individual gate into the USB OHCI and gadget blocks. This clock is called usb-bus-clock, and we need to replace the old use of the USB PLL (upll) directly with the new usb-bus-host. The S3C2410 clock driver has been updated already to provide a virtual clock which is a child of the UPLL to maintain compatibility. The S3C2412 clock driver correctly enables the PLL when either usb-bus clock is active. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* USB: OHCI avoids root hub timer pollingDavid Brownell2006-09-271-0/+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: S3C2410: use clk_enable() to ensure 48MHz to OHCI coreBen Dooks2006-04-141-8/+24
| | | | | | | | | | | | | | Get the "usb-bus" clock and ensure it is enabled when the OHCI core is in use. It seems that a few bootloaders do not enable the UPLL at startup, which stops the OHCI core having a 48MHz bus clock. The improvements to the clock framework for the s3c24xx now allow the USB PLL to be started and stopped when being used.

* [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/+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.
