[PATCH v5 0/5] phy: fsl-imx8mq-usb: few improvements

[Xu Yang]

This patchset is a continuous of v2, it mainly resolves some concerns
reported by sashiko-bot.

Patch #1 fix Type-C switch resource leak if probe() fails.
Patch #3 add runtime PM support to avoid register access issue if the
      USB controller enters into runtime suspended state, in this state
      accessing USB PHY register may lack some resources. This will also
      avoid regulator leak if power_on() fails.
Patch #4 add debug control register regmap
Patch #5 correct i.MX8MP USB runtime wakeup issue after introduce runtime
      PM support.
