* Remove bogus detach routinesJohn Baldwin2024-11-051-1/+0
| | | | | | | | | These drivers are not bus drivers, and would need proper detach routines that tore down state stored in the softc. Better to just fail detach outright instead of an incorrect success. Reviewed by: imp Differential Revision: https://reviews.freebsd.org/D47389
* sff: Add SFP driver (fdt-based draft)Dmitry Salychev2023-08-182-0/+190
This basic version of the driver obtains properties of the "sff,sfp" compatible devices and implements a simple interface to provide an I2C bus device for the rest of the drivers (e.g. to implement SIOCGI2C). Both of the interface and driver are subjects for a further generalization to be used in case of non-FDT and non-arm64 platforms.
