Return the same clock for usbh and usbd on BCM6318 to prevent the clock getting disabled despite being supposed to be enabled, e.g. by the following sequence: clk_enable(usbh); <- usbh->usage = 1, enabled clk_enable(usbd); <- usbd->usage = 1, enabled (no effect) clk_disable(usbd); <- usbd->usage = 0, -> disabled!
