Hi all,

Thanks for the feedback on v4 [1].

This patchset aims to support flags for e.g. over-current active low or port
permanantly attached which are provided in the USB3 glue layer.

In v4 the patchset depends on Lucas' i.MX8MP power-domains patchset [2].
Because of that the 'phy' clock usage can be dropped, as now power domains
take care of the clocks. Due to powering up/down the glue layer settings
will have to be reapplied during resume.

Changes in v5:
* Added Reviewed-by: Li Jun to PATCH 1 & 4
* Added Reviewed-by: Rob Herring to PATCH 2
* Added comment in PATCH 3 why reprogramming is necessary in resume

Changes in v4:
* Depends on Lucas' i.MX8MP power-domains patchset
* removed 'phy' clock usage from dwc3-imx8mp.c
* Reapply glue layer settings upon resume

Changes in v3:
* Rename existing member for clarity
* Moved feature implementation from phy-fsl-imx8mq-usb.c to dwc3-imx8mp.c
