The Maxim max30101 irs the replacement for the max30105, which is no
longer recommended for future designs.

The max30101 does not require new properties, and it can be described
with the existing ones for the max30105.

Given there were no driver changes, is it fully compatible?
i.e. Should we have a fallback compatible here?

properties:
  compatible:
    oneOf:
       - items:
           - const: maxim,max30101
           - const: maxim,max30105
       - enum:
           - maxim,max30102
           - maxim,max30105

So that a DTS file could use
compatible = "maxim,max30101", "maxim,max30105"
and work with older kernels as well as new ones that understand the new ID?

According to the manufacturer, it is fully compatible, and apart from
the pinout, I could not find any difference beyond the device description.

I like the idea of having a fallback compatible for older kernels, so I
will add it to v2 as you suggested.

Thanks and best regards,
