Start clocks on rising edge of the Vbus signal, stop clocks on falling edge of the Vbus signal. Add suspend/resume with wakeup support. This series is based on linux-next and depends on this complete series: https://lkml.org/lkml/2015/1/12/209 which is currently only partially pushed to linux-next, the following patch should be pushed along with this series: https://lkml.org/lkml/2015/1/12/212 Changes since v5: * Some boards does not support configuring a GPIO interrupt on a specific edge (rising only or falling only). As suggested added a config boolean to distinguish between boards with and without support * Added a missing mutex_lock()/unlock() in usba_udc_suspend(), we need to protect usba_stop() because usba_start() and usba_stop() can still be called by Vbus IRQ handler. * Rebased the full series on linux-next * Patch cleaning with the help of checkpatch.pl Changes since v4: * Now using IRQ_NOAUTOEN flag to remove the unused check for udc->driver is not NULL in the Vbus IRQ. * Reworked the start/stop of clocks on Vbus edges to prepare for suspend/resume support, factorised start and stop procedures * New patch, suspend/resume for USBA with wakeup support Changes since v3: * Added stable tag for the first patch * As suggested, removed the unused check for udc->driver is NULL in Vbus IRQ by requesting IRQ after udc->driver is set and by releasing IRQ before udc->driver is cleared * Rebased the core patch of this series against the just explained changes Changes since v2: * Use spin_lock_irqsave/unlock_irqrestore instead of spin_lock/unlock in threaded interrupt because we are not in irq context anymore * Removed useless and probably harmful IRQF_NO_SUSPEND from devm_request_threaded_irq() flags Changes since v1: * Using a threaded irq and mutex instead of spinclock as suggested * Moved a silently fixed bug in a separate patch (1/2) Sylvain Rochet (5): USB: gadget: atmel_usba_udc: Fixed vbus_prev initial state USB: gadget: atmel_usba_udc: Request an auto disabled Vbus signal IRQ instead of an auto enabled IRQ request followed by IRQ disable USB: gadget: atmel_usba_udc: Start clocks on rising edge of the Vbus signal, stop clocks on falling edge of the Vbus signal USB: gadget: atmel_usba_udc: Prepare for IRQ single edge support USB: gadget: atmel_usba_udc: Add suspend/resume with wakeup support drivers/usb/gadget/udc/atmel_usba_udc.c | 244 +++++++++++++++++++++++--------- drivers/usb/gadget/udc/atmel_usba_udc.h | 9 +- 2 files changed, 188 insertions(+), 65 deletions(-) -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
