/** * IIO_CONST_ATTR_SCAN_EL_TYPE - attr to specify the data format of a scan el * @name: the scan el name (may be more general and cover a set of scan elements * @_sign: either s or u for signed or unsigned * @_bits: number of actual bits occuplied by the value * @_storagebits: number of bits _bits is padded to when read out of buffer **/ #define IIO_CONST_ATTR_SCAN_EL_TYPE(_name, _sign, _bits, _storagebits) \ IIO_CONST_ATTR(_name##_type, #_sign#_bits"/"#_storagebits); There are cases where bits < storagebits and the result is not alligned to the LSB. Lets say we have an 10-bit ADC. The output is stored in a 16-bit word, with four leading zeros, then the 10-bit datum, followed by 2 don't care bits. So it would be good to provide an additional shift value? Or how shall we handle these cases?
