The Maxim max30101 is the replacement for the max30105, which is no
longer recommended for new designs [1].
The max30101 is described as a pulse oximeter and heart-rate sensor,
as opposed to the max30105, which is described as an optical sensor for
smoke detection applications. In the end, the internal structure is
identical, as well as the register map, voltages and sensitivity. Only
the pinout has changed, which is not relevant for the driver.
A new compatible has been added, but the logic used for the max30105 can
be re-used for the new part.

The Maxim max30101 is 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, which will be used as a
fallback compatible.

The Maxim max30101 is the replacement for the max30105, which is no
longer recommended for future designs.
Their internal structure is identical, as well as the register map,
configuration options and sensitivity, which allows for code recycling.

Thanks,
Series applied to the togreg branch of iio.git and initially pushed out
as testing to get it some build testing from 0-day.
Thanks,
