dpll: Add basic Microchip ZL3073x support

2025-07-10T02:08:52Z

Microchip Azurite ZL3073x represents chip family providing DPLL and optionally PHC (PTP) functionality. The chips can be connected be connected over I2C or SPI bus. They have the following characteristics: * up to 5 separate DPLL units (channels) * 5 synthesizers * 10 input pins (references) * 10 outputs * 20 output pins (output pin pair shares one output) * Each reference and output can operate in either differential or single-ended mode (differential mode uses 2 pins) * Each output is connected to one of the synthesizers * Each synthesizer is driven by one of the DPLL unit The device uses 7-bit addresses and 8-bits values. It exposes 8-, 16-, 32- and 48-bits registers in address range <0x000,0x77F>. Due to 7bit addressing, the range is organized into pages of 128 bytes, with each page containing a page selector register at address 0x7F. For reading/writing multi-byte registers, the device supports bulk transfers. Add basic functionality to access device registers, probe functionality both I2C and SPI cases and add devlink support to provide info and to set clock ID parameter.

ixgbe: add initial devlink support

2025-04-15T14:36:32Z

Add an initial support for devlink interface to ixgbe driver. Similarly to i40e driver the implementation doesn't enable devlink to manage device-wide configuration. Devlink instance is created for each physical function of PCIe device. Create separate directory for devlink related ixgbe files and use naming scheme similar to the one used in the ice driver. Add a stub for Documentation, to be extended by further patches. Change struct ixgbe_adapter allocation to be done by devlink (Przemek), as suggested by Jiri.

i40e: Align devlink info versions with ice driver and add docs

2023-10-19T16:03:56Z

Align devlink info versions with ice driver so change 'fw.mgmt' version to be 2-digit version [major.minor], add 'fw.mgmt.build' that reports mgmt firmware build number and use '"fw.psid.api' for NVM format version instead of incorrect '"fw.psid'. Additionally add missing i40e devlink documentation.
