usb: kconfig: fix warning of select USB_OTG

2015-11-20T00:31:42+00:00

When choose randconfig for kernel build, it reports below warning:
"warning: (USB_OTG_FSM && FSL_USB2_OTG && USB_MV_OTG) selects USB_OTG
which has unmet direct dependencies (USB_SUPPORT && USB && PM)"

In fact, USB_OTG is visible symbol and depends on PM, so the driver
needs to depend on it to reduce dependency problem.

usb: Add device quirk for Logitech PTZ cameras

2015-10-04T10:01:13+00:00

Add a device quirk for the Logitech PTZ Pro Camera and its sibling the
ConferenceCam CC3000e Camera.
This fixes the failed camera enumeration on some boot, particularly on
machines with fast CPU.

Tested by connecting a Logitech PTZ Pro Camera to a machine with a
Haswell Core i7-4600U CPU @ 2.10GHz, and doing thousands of reboot cycles
while recording the kernel logs and taking camera picture after each boot.
Before the patch, more than 7% of the boots show some enumeration transfer
failures and in a few of them, the kernel is giving up before actually
enumerating the webcam. After the patch, the enumeration has been correct
on every reboot.

usb: otg: don't set a_alt_hnp_support feature for OTG 2.0 device

2015-10-04T09:51:58+00:00

Since a_alt_hnp_support is obsolete in OTG 2.0, HNP capable host should
send this set feature request only if the otg device is connecting to a
non-HNP port and it's compliant with OTG 1.x revision. This is done by
checking its otg descriptor length, OTG 2.0 uses usb_otg20_descriptor
which has different length than OTG 1.x using usb_otg_descriptor.
