2013-12-08usb: hcd: move controller wakeup setting initialization to individual driverPeter Chen64-16/+92
Individual controller driver has different requirement for wakeup setting, so move it from core to itself. In order to align with current etting the default wakeup setting is enabled (except for chipidea host). Pass compile test with below commands: make O=outout/all allmodconfig make -j$CPU_NUM O=outout/all drivers/usb Signed-off-by: Peter Chen <peter.chen@freescale.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2013-12-08usb: hcd: Initialize USB phy if neededValentine Barshak1-0/+18
This adds external USB phy support to USB HCD driver that allows to find and initialize external USB phy, bound to the HCD, when the HCD is added. The usb_add_hcd function returns -EPROBE_DEFER if the USB phy, bound to the HCD, is not ready. If no USB phy is bound, the HCD is initialized as usual.

2013-12-08usb: hcd: Remove USB phy if neededValentine Barshak2-1/+14
This adds remove_phy flag to the HCD structure. If the flag is set and if hcd->phy is valid, the phy is shutdown and released whenever usb_add_hcd fails or usb_hcd_remove is called. This can be used by the HCD drivers to auto-remove the external USB phy when it is no longer needed.
