This patchset is composed with : - bindings of the PHYs - bindings of the USB Control Glue - PHY Drivers - USB Control Glue driver Device Tree nodes will be added in a separate patchset. The Amlogic G12A USB Complex is composed of : - 2 USB Controllers : * DWC3 for USB2 and USB3 Host functionality * DWC2 for USB2 Peripheral functionality - 2 USB2 OTG PHYs, only a single one will be routed to either DWC2 to DWC3 - 1 USB3 PHY shared with PCIE funcionnality - A Glue to control PHY routing, setup and OTG detection The Glue configures the UTMI 8bit interfaces for the USB2 PHYs, including routing of the OTG PHY between the DWC3 and DWC2 controllers, and setups the on-chip OTG mode selection for this PHY. The PHYs are children of the Glue node since the Glue controls the interface with the PHY, not the DWC3 controller. The PHY interconnect is handled into ports subnodes, which eases describing which PHY is enabled (like the USB3 shared PHY) and futures layouts on derivatives of the G12A Family. This drivers supports the on-probe setup of the OTG mode, and manually via a debugfs interface. The IRQ mode change detect is yet to be added in a future patchset, mainly due to lack of hardware to validate on.
