[PATCH 00/11] add debugfs consumers, tracepoints and rebuild QMU

[Chunfeng Yun]

In order to help debug, this series add more debugfs consumers,
introduce a few initial tracepoints;
And support new features introduced by USB3 Gen2 ISOC:
1. TXCSR/RXCSR registers are adjusted to support greater MULT
   and MAX_PKT
2. QMU format is also improved
last, some small problems are fixed.

  usb: mtu3: check return value of devm_extcon_register_notifier()
  usb: mtu3: print useful information also for device and host modes
  usb: mtu3: remove unnecessary local variable @req
  usb: mtu3: rebuild the code of getting vbus regulator
  usb: mtu3: fix transfer error of USB3 Gen2 isoc
  usb: mtu3: rebuild qmu_gpd struct to prepare to support new QMU format
  usb: mtu3: supports new QMU format
  usb: mtu3: add debugfs interface files
  usb: mtu3: move vbus and mode debugfs interfaces into mtu3_debugfs.c
  usb: mtu3: add tracepoints to help debug
  usb: mtu3: add a function to switch mailbox state to string
