Subject: [PATCH v4 0/3] add support for the lmk04832

Hi,

The LMK04832 is an ultra-high performance clock conditioner with JEDEC
JESD204B support and is also pin compatible with the LMK0482x family of
devices.

This driver adds initial support to configure the LMK04832 clocks using
the clock framework.

This has been tested on a system using JESD204B subclass 1.

At the moment, the VCO rate has to be set manually from the devicetree
and a dclk (or sclk) rate change isn't propagated to the VCO
automatically.

Changes since v1:
- add yaml devicetree documentation,
- add links to datasheet,
- use {u8,u16,u32} instead of Uint_ variants,
- drop redundant debugfs code,
- use a pointer to device_info instead of struct copy,
- add of_device_id table,
- add support for SYSREF digital delay and JESD204B subclass 1

Changes since v2:
- fix dt-bindings documentation, apologies for the broken build
- fix property vendor prefixes
- split dt-bindings into a separate patch

Changes since v3:
- add missing properties in dt-bindings

Thanks for your time,
Liam
