This series adds USB 3.0 support for the CAT874 platform, including a
new driver for the TI HD3SS3220 USB Type-C DRP port controller.

This patch series supports:
1) Host hotplug operation
2) Device hot plug operation
3) USB type-C data_role switch
   (Tested with 2 RZ/G2E boards connected with a Type-C cable)

This patchset is based on linux_next next-20190306 branch.

V1-->V2
  * Use USB role class instead of extcon to receive connect and disconnect
    events and also for the dual role switch.
  * Dropped patch 6
  * Squashed patch 8 and patch 9
