[PATCH 2/4] dt-bindings: iio: accel: bma255: Add bosch,bmc156_accel

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

 



BMC156 is very smilar to BMC150, but it has only one accelerometer
interrupt pin. It would make sense if only INT1 was exposed but someone
at Bosch was crazy and decided to only have an INT2 pin.

In this case, it does not make sense if the first interrupt pin is
treated as INT1 (since that pin does not exist). Add a note to the
bindings that the first interrupt pin is treated as INT2 for BMC156.
