s='logsubject'>usb: dwc3: apple: Only support a single reset controllerSven Peter As pointed out by Philipp, Apple's dwc3 controller only uses a single reset line and there's thus no need to use reset controller array functions. The only functional change here is replacing devm_reset_control_array_get_exclusive with devm_reset_control_get_exclusive. The rest are only cosmetic changes to replace "resets" with "reset".

Specifically, the PHY first has to go through initial bringup (which requires knowledge of the lane mode and orientation) before dwc3 itself can be brought up and can then finalize the PHY configuration. Additionally, dwc3 has to be teared down and re-initialized whenever the cable is changed due to hardware quirks that prevent a new device from being recognized and due to the PHY being unable to switch lane mode or orientation while dwc3 is up and running. These controllers also have a Apple-specific MMIO region after the common dwc3 region where some controls have to be updated. PHY bringup and shutdown also requires SUSPHY to be enabled for the ports to work correctly. In the future, this driver will also gain support for USB3-via-USB4 tunneling which will require additional tweaks. Add a glue driver that takes of all of these constraints.
