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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
