- - Device configuration version customized by OEM
- Flash Update
- ============
- The ``zl3073x`` driver implements support for flash update using the
- ``devlink-flash`` interface. It supports updating the device flash using a
- combined flash image ("bundle") that contains multiple components (firmware
- parts and configurations).
- During the flash procedure, the standard firmware interface is not available,
- so the driver unregisters all DPLLs and associated pins, and re-registers them
- once the flash procedure is complete.
- The driver does not support any overwrite mask flags.
