| 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. |
