Hello,
This series first adds support for parts missing from mcp4531 driver
(MCP454x, MCP456x, MCP464x and MCP466x). It then introduces the necessary
device tree binding to perform DT boot.
Tested with MCP4561-103 and MCP4561-503 (DT boot).
Best regards,
Florian

Add the device tree documentation for all the supported parts. Apart the
compatible string and standard I2C binding, no other binding is currently
needed.

I was not aware that the i2c subsystem had a facility to match the compatible
string against i2c_device_id. Good to know.

Your compatible string is missing the vendor ID (microchip). This is the only
objection that I can see to your proposition. Let's wait to hear from a DT
maintainer.
