There is already a glue layer driver dwc3-imx8mp, but unfortunately this driver does not use the glue area at all, it only handles wakeup-support which is done in the HSIO BLK_CTRL area (0x32f10100), accordingly the driver only uses the hsio clock. The driver which actually uses the USB3 glue area is phy-fsl-imx8mq-usb. As the name indicates PHY is configured in the corresponding registers, which are part of the USB3 glue layer. This make is it unclear for me which driver should handle the required features above. dwc3-imx8mp, the glue layer driver, does not touch the glue area at all, but the HSIO BLK_CTRL area. phy-fsl-imx8mq-usb only touches the PHY registers in the glue layer. Neither does map the USB3 control register from the glue layer.
