* USB: OHCI: remove OHCI SH platform driverFlorian Fainelli2012-10-221-141/+0
| | | | | | | | | All users have been converted to use the OHCI platform driver instead, thus making ohci-sh obsolete, so remove it. Signed-off-by: Florian Fainelli <florian@openwrt.org> Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* USB: ohci-sh.c: remove err() usageGreg Kroah-Hartman2012-04-271-4/+4
| | | | | | | | | err() was a very old USB-specific macro that I thought had gone away. This patch removes it from being used in the driver and uses dev_err() instead. CC: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* OHCI: remove uses of hcd->stateAlan Stern2011-11-181-1/+0
| | | | | | | | | This patch (as1500) removes all uses of the objectionable hcd->state variable from the ohci-hcd family of drivers. It is replaced by a private ohci->rh_state field, just as in uhci-hcd and ehci-hcd. Signed-off-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* usb: ohci-sh: Set IRQ as shared.Paul Mundt2010-11-011-1/+1
| | | | | | | | The SH USB interface has both OHCI and EHCI modes that share the same interrupt. Flag the OHCI IRQ as shared in preparation for EHCI support. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* 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.

* usb host: fix platform driver hotplug/coldplugKay Sievers2008-04-111-0/+1
| | | | | | | | | | | | | Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable USB HCDs, to allow re-enable auto loading.
