Since the usb-phy clocks are not connected to the 32khz clock-in, they only have 24Mhz as the clock source. If we want to wake up system via usb device, we should hold the 24Mhz osc during suspend. This Patch has tested on chromebook jerry board, with another patch[0], we can wakeup system via usb keyboard.
