[PATCH 0/2] usb: override hub device bInterval with device node

[Ikjoon Jang]

This patchset enables hard wired hub device to use different bInterval
from its descriptor when the hub has a combined device node.

When we know the specific hard wired hub supports changing its polling
interval, we can adjust hub's interval to reduce the time of waking up
from autosuspend or connect detection of HIDs.

  dt-bindings: usb: add "hub,interval" property
  usb: overridable hub bInterval by device node
