  19                 generalize well and hence are not documented in this file.

  40 Description:
  41                 Some devices have internal clocks.  This parameter sets the
  42                 resulting sampling frequency.  In many devices this
  43                 parameter has an effect on input filters etc. rather than
  44                 simply controlling when the input is sampled.  As this
  45                 effects data ready triggers, hardware buffers and the sysfs
  46                 direct access interfaces, it may be found in any of the
  47                 relevant directories.  If it effects all of the above
  48                 then it is to be found in the base device directory.

1018 Description:
1019                 Description of the scan element data storage within the buffer
1020                 and hence the form in which it is read from user-space.
1021                 Form is [be|le]:[s|u]bits/storagebits[>>shift].
1022                 be or le specifies big or little endian. s or u specifies if
1023                 signed (2's complement) or unsigned. bits is the number of bits
1024                 of data and storagebits is the space (after padding) that it
1025                 occupies in the buffer. shift if specified, is the shift that
1026                 needs to be applied prior to masking out unused bits. Some
1027                 devices put their data in the middle of the transferred elements
1028                 with additional information on both sides.  Note that some
1029                 devices will have additional information in the unused bits
1030                 so to get a clean value, the bits value must be used to mask
1031                 the buffer output value appropriately.  The storagebits value
1032                 also specifies the data alignment.  So s48/64>>2 will be a
1033                 signed 48 bit integer stored in a 64 bit location aligned to
1034                 a 64 bit boundary. To obtain the clean value, shift right 2
1035                 and apply a mask to zero the top 16 bits of the result.
1036                 For other storage combinations this attribute will be extended
1037                 appropriately.
