OMAP4: USBHS: Enable remote wakeup using I/O pads
This patch implements remote wakeup using I/O pads of
USB ports. When there is no device connected to USB
host (EHCI/OHCI) the clocks are disabled in the bus
suspend path. The clocks are enabled when I/O
interrupt triggers. The USBHS clock and port clocks
are enabled using workqueue triggered by PRCM
interrupt handler of I/O.
omap_hwmod API's are used to configure mux settings
and to enable IO pad wakeup capability for EHCI/OHCI.
Also omap_hwmod API is used to check for IO-PAD wakeup
event status.
