This patchset must go on top of Paolo Pisoli's "fpga: lattice machxo2: Add Lattice MachXO2 support" Don't set or use drvdata in the FPGA common manager/bridge/region code. Change API for manager, bridge, and region to each include functions for create, free, register, and unregister. This involved adding new create/free functions and changing the existing register/unregister functions to take the corresponding manager/bridge/region struct as the only parameter. Setting drvdata is fine for DT based devices which have one manager, bridge, or region device per platform device. However, PCIe based devices may have multiple FPGA mgr/bridge/regions under one PCIe device. Without these changes, PCIe-based solutions have to create an extra device for each child mgr/bridge/region to hold drvdata.
