There's no power/persist file for hubs. And CONFIG_USB_PERSIST was removed in v2.6.26. Update the description of power/persist accordingly. Also remove the line on its default value. It is not entirely correct, as CONFIG_USB_DEFAULT_PERSIST and the USB_QUIRK_RESET flag influence the default. It is not needed to understand this file anyhow.

Resuming a powered down port sometimes results in the port state being stuck in the training sequence. hub 3-0:1.0: debounce: port 1: total 2000ms stable 0ms status 0x2e0 port1: can't get reconnection after setting port power on, status -110 hub 3-0:1.0: port 1 status 0000.02e0 after resume, -19 usb 3-1: can't resume, status -19 hub 3-0:1.0: logical disconnect on port 1 In the case above we wait for the port re-connect timeout of 2 seconds and observe that the port status is USB_SS_PORT_LS_POLLING (although it is likely toggling between this state and USB_SS_PORT_LS_RX_DETECT). This is indicative of a case where the device is failing to progress the link training state machine. It is resolved by issuing a warm reset to get the hub and device link state machines back in sync. hub 3-0:1.0: debounce: port 1: total 2000ms stable 0ms status 0x2e0 usb usb3: port1 usb_port_runtime_resume requires warm reset hub 3-0:1.0: port 1 not warm reset yet, waiting 50ms usb 3-1: reset SuperSpeed USB device number 2 using xhci_hcd After a reconnect timeout when we expect the device to be present, force a warm reset of the device. Note that we can not simply look at the link status to determine if a warm reset is required as any of the training states USB_SS_PORT_LS_POLLING, USB_SS_PORT_LS_RX_DETECT, or USB_SS_PORT_LS_COMP_MOD are valid states that do not indicate the need for warm reset by themselves.

When a USB device is disconnected, usb_unbind_interface is called, which tries to enable and disable LPM. usb_enable_lpm also try to send a control command SET SEL to the device. Since device is already disconnected, therefore it does not make sense to execute usb_(en/dis)able_lpm. This patch returns from usb_(en/dis)able_lpm, if device was not in default state atleast.

As best case, a host controller should support U0 to U1 switching for the devices connected below any tier of hub level supported by usb specification. Therefore xhci_check_tier_policy should always return success as default implementation. A host should be able to issue LGO_Ux after the timeout calculated as per definition of system exit latency defined in C.1.5.2. Therefore xhci_calculate_ux_timeout returns ux_params.sel as the default implementation. Use default calculation in absence of any vendor specific limitations.
