Add support for Microchip Azurite DPLL/PTP/SyncE chip family that provides DPLL and PTP functionality. This series bring first part that adds the common MFD driver that provides an access to the bus that can be either I2C or SPI.
The next series will bring the DPLL driver that will covers DPLL functionality. And another ones will bring PTP driver and flashing capability via devlink.
Testing was done by myself and by Prathosh Satish on Microchip EDS2 development board with ZL30732 DPLL chip connected over I2C bus.
Patch breakdown =============== Patch 1 - Common DT schema for DPLL device and pin Patch 3 - Basic support for I2C, SPI and regmap Patch 4 - Devlink registration Patches 5-6 - Helpers for accessing device registers Patches 7-8 - Component versions reporting via devlink dev info Patches 9-10 - Helpers for accessing register mailboxes Patch 11 - Clock ID generation for DPLL driver Patch 12 - Export strnchrnul function for modules (used by next patch) Patch 13 - Support for MFG config initialization file Patch 14 - Fetch invariant register values used by DPLL and later by PTP driver
