Form is [be|le]:[s|u]bits/storagebits[>>shift]. be or le specifies big or little endian. s or u specifies if signed (2's complement) or unsigned. bits is the number of bits of data and storagebits is the space (after padding) that it occupies in the buffer. shift if specified, is the shift that needs to be applied prior to masking out unused bits. Some devices put their data in the middle of the transferred elements with additional information on both sides. Note that some devices will have additional information in the unused bits so to get a clean value, the bits value must be used to mask the buffer output value appropriately. The storagebits value also specifies the data alignment. So s48/64>>2 will be a signed 48 bit integer stored in a 64 bit location aligned to a 64 bit boundary. To obtain the clean value, shift right 2 and apply a mask to zero the top 16 bits of the result. For other storage combinations this attribute will be extended appropriately.

Note these are not dependent on what is enabled and may not be contiguous. Thus for user-space to establish the full layout these must be used in conjunction with all _en attributes to establish which channels are present, and the relevant _type attributes to establish the data storage format.
