Description:
- If CONFIG_PM_RUNTIME is set and a USB 2.0 lpm-capable device
- is plugged in to a xHCI host which support link PM, it will
- perform a LPM test; if the test is passed and host supports
- USB2 hardware LPM (xHCI 1.0 feature), USB2 hardware LPM will
- be enabled for the device and the USB device directory will
- contain a file named power/usb2_hardware_lpm. The file holds
- a string value (enable or disable) indicating whether or not
- USB2 hardware LPM is enabled for the device. Developer can
- write y/Y/1 or n/N/0 to the file to enable/disable the
- feature.
