Subject: Re: [PATCH net-next v4 11/12] microchip: lan865x: add driver support
 for Microchip's LAN865X MAC-PHY

Ok this tripped me up.

Initially I set compatible = "microchip,lan8650", and did not get the
driver to probe, so I got carried away with adding things that were not
necessary.

I dropped my patch and tested again.
What does work is setting:

compatible = "microchip,lan8651"

 - or - 

compatible = "microchip,lan8651", "microchip,lan8650"

but just compatible = "lan8650" does not work.

Also I'm getting the output
[    0.125056] SPI driver lan8650 has no spi_device_id for microchip,lan8651

As Conor pointed out setting the define DRV_NAME to "lan8651" fixes
that.
Setting the define to "lan8650" yet gets the spi module to log the 'no spi_device id..'.

I don't really have an opinion here, but I think there is a risk that
more than one dev might stumble on the same thing as me and expect that
either or should work.
