2017-04-18usb: fix some references for /proc/bus/usbMauro Carvalho Chehab
Since when we got rid of usbfs, the /proc/bus/usb is now elsewhere. Fix references for it. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com> Acked-by: Serge Hallyn <serge@hallyn.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2016-11-03usb: ch9: make usb_endpoint_maxp() return only packet sizeFelipe Balbi
Now that we have a helper to gather periodic endpoints' multiplier bits from wMaxPacketSize and every driver is using it, we can safely make sure that usb_endpoint_maxp() returns only bits 10:0 of wMaxPacketSize which is where the actual packet size lies.

2016-10-31usb: add helper to extract bits 12:11 of wMaxPacketSizeFelipe Balbi
According to USB Specification 2.0 table 9-4, wMaxPacketSize is a bitfield. Endpoint's maxpacket is laid out in bits 10:0. For high-speed, high-bandwidth isochronous endpoints, bits 12:11 contain a multiplier to tell us how many transactions we want to try per uframe. This means that if we want an isochronous endpoint to issue 3 transfers of 1024 bytes per uframe, wMaxPacketSize should contain the value: 1024 | (2 << 11) or 5120 (0x1400). In order to make Host and Peripheral controller drivers' life easier, we're adding a helper which returns bits 12:11. Note that no care is made WRT to checking endpoint type and gadget's speed. That's left for drivers to handle. Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>

2016-03-04usb: ch9: Add size macro for SSP dev cap descriptorJohn Youn
The SuperspeedPlus Device Capability Descriptor has a variable size depending on the number of sublink speed attributes. This patch adds a macro to calculate that size. The macro takes one argument, the Sublink Speed Attribute Count (SSAC) as reported by the descriptor in bmAttributes[4:0]. See USB 3.1 9.6.2.5, Table 9-19.

2016-02-14usb: Add USB 3.1 Precision time measurement capability descriptor supportMathias Nyman
USB 3.1 devices that support precision time measurement have an additional PTM cabaility descriptor as part of the full BOS descriptor Look for this descriptor while parsing the BOS descriptor, and store it in struct usb_hub_bos if it exists.

2016-02-14usb: Add USB3.1 SuperSpeedPlus Isoc Endpoint Companion descriptorMathias Nyman
USB3.1 specifies a SuperSpeedPlus Isoc endpoint companion descriptor which is returned as part of the devices complete configuration descriptor. It contains number of bytes per service interval which is needed when reserving bus time in the schedule for transfers over 48K bytes per service interval. If bmAttributes bit 7 is set in the old SuperSpeed Endpoint Companion descriptor, it will be ollowed by the new SuperSpeedPlus Isoc Endpoint Companion descriptor.

Add a new USB_SPEED_SUPER_PLUS device speed, and make sure usb core can handle the new speed. In most cases the behaviour is the same as with USB_SPEED_SUPER SuperSpeed devices. In a few places we add a "Plus" string to inform the user of the new speed. Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2013-01-24usb: Using correct way to clear usb3.0 device's remote wakeup feature.Lan Tianyu
Usb3.0 device defines function remote wakeup which is only for interface recipient rather than device recipient. This is different with usb2.0 device's remote wakeup feature which is defined for device recipient. According usb3.0 spec 9.4.5, the function remote wakeup can be modified by the SetFeature() requests using the FUNCTION_SUSPEND feature selector. This patch is to use correct way to disable usb3.0 device's function remote wakeup after suspend error and resuming. This should be backported to kernels as old as 3.4, that contain the commit 623bef9e03a60adc623b09673297ca7a1cdfb367 "USB/xhci: Enable remote wakeup for USB3 devices."
