[PATCH]usb:host:xhci AMD Promontory USB disable port support

2017-05-25 Thread Jiahau Chang
There is some limitation for AMD Promontory xHCI host to disable USB port function. It will enable USB wake-up function then cause USB disable port feature to fail. Workaround this issue on Promontory xHCI host is clear PORT_WAKE_BITS. Signed-off-by: Jiahau Chang --- drivers/usb/host/xhci-hu
