From: Keshava Munegowda <Keshava_mgowda@ti.com>
For ehci and ohci hwmods,
the omap3 and omap4 I/O wakeup capablity is enabled.
In case of system global suspend, The ehci/ohci device
connection/disconnection and remote wakeup wakesup the system.
This patch series is based on
1. I/O pads initialization to ehci and ohci hwmod
2. Runtime PM support of usbhs of omap3 and omap4
These patches are avilable at branch kmg-usbhs-pm
code repository : git://gitorious.org/~kmg/mirrors/kmg-usbhs-pm.git
3. Kevin's pm branch
Keshava Munegowda (1):
arm: omap: usb: enable I/O wakeups of ehci and ohci hwmods of omap3
Kishon Vijay Abraham (1):
arm: omap: usb: enable I/O wakeups of ehci and ohci hwmods of omap4

Currently, the IO pad wakeup for these pins is enabled unconditionally. While having it enabled as a wakeup source by default is fine, it should not generate wakeups if the user has disable them by doing: $ echo disabled > /sys/devices/.../power/wakeup IOW, whether wakeups are enabled or not should depend on the driver checking device_may_wakeup() Kevin ^ permalink raw reply [flat|nested] 11+ messages in thread
