Changes in v3:
- Removed 2nd ops struct for Octeon TX2 and removed "const" from the octeon_spi_ops declaration. This makes a more elegant switch to the Octeon TX2 functions possible, as suggested by Daniel
- Remove driver_data struct, as its not needed. The distinction between PCI based on non-PCI based probing can be made via a common Octeon TX & TX2 DT property can be made.
Changes in v2:
- Newly added to this series
- Removed inclusion of "common.h"
- Added "depends on DM_PCI" to Kconfig
- Tested on MIPS Octeon and ARM Octeon TX2
- Fixed issues with Octeon TX2 registration. Now only one driver is registered and the "ops" is overwritten in the Octeon TX2 case.
- Use dev_get_driver_data() to get the driver data struct
- Removed "struct pci_device_id" definition and U_BOOT_PCI_DEVICE() as its not needed for the PCI based probing on Octeon TX2
