[PATCH 1/2] dt-bindings: iio: light: ltrf216a: Document LTR-308 support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Document LiteOn LTR-308 support in LTR-F216A bindings.

The two devices seem to have almost identical register map, except that
the LTR-308 does not have three CLEAR_DATA registers, which are unused
by this driver. Furthermore, LTR-308 and LTR-F216A use different lux
calculation constants, 0.6 and 0.45 respectively.
