usb: define HCD_USB31 speed option for hosts that support USB 3.1 features

2015-10-04T09:34:17+00:00

Hosts that support USB 3.1 Enhaned SuperSpeed can set their speed to
HCD_USB31 to let usb core and host drivers know that the controller
supports new USB 3.1 features.

make sure usb core handle HCD_USB31 hosts correctly, for now similar
to HCD_USB3.

usb: hcd.h: Fix the values of SetHubDepth and GetPortErrorCount to match USB 3.1 specification

2015-08-08T22:17:31+00:00

>From the usb 3.1 spec available at http://www.usb.org/developers/docs/
table 10-7 (Hub Class Requests) specifies the values for SetHubDepth and
GetPortErrorCount as:

Request			bmRequestType	bRequest		wValue		wIndex	wLength	Data
SetHubDepth		00100000B	SET_HUB_DEPTH		Hub Depth	Zero	Zero	None
GetPortErrorCount	10100011B	GET_PORT_ERR_COUNT	Zero		Port	Two	Number of Link Errors on this port

Fix these two values to match the spec.

USB: hcd.h : Removed an unnecessary function prototype usb_find_interface_driver()

2015-05-31T06:51:23+00:00

This function is used to call in early version of linux kernel in order
to find out the interface used by a usb device. But now it's use is
completely abolished. So,it would be relevant to remove this obselete
function from kernel mainline.

USB: add flag for HCDs that can't receive wakeup requests (isp1760-hcd)

2015-01-31T17:05:06+00:00

Currently the USB stack assumes that all host controller drivers are
capable of receiving wakeup requests from downstream devices.
However, this isn't true for the isp1760-hcd driver, which means that
it isn't safe to do a runtime suspend of any device attached to a
root-hub port if the device requires wakeup.

This patch adds a "cant_recv_wakeups" flag to the usb_hcd structure
and sets the flag in isp1760-hcd.  The core is modified to prevent a
direct child of the root hub from being put into runtime suspend with
wakeup enabled if the flag is set.
