iio: accel: sca3300: Add inclination channels
Different from SCA3300, SCL3300 can output inclination angles.
Angles are formed from acceleration with following equations:
ANG_X = atan2(accx , sqrt(pow(accy , 2) + pow(accz , 2)))
ANG_Y = atan2(accy , sqrt(pow(accx , 2) + pow(accz , 2)))
ANG_Z = atan2(accz , sqrt(pow(accx , 2) + pow(accy , 2)))
The commit adds the output of the raw value, scale
and scale_available of angles.
New interfaces:
in_incli_scale
in_incli_scale_available
in_incli_x_raw
in_incli_y_raw
in_incli_z_raw
Data converted by application of scale to degrees.
