provided by a separate driver for other hardware (e.g.

Description:

Some devices have internal clocks. This parameter sets the
|
|
|
|
resulting sampling frequency. In many devices this
|
|
|
|
parameter has an effect on input filters etc rather than
|
|
|
|
simply controlling when the input is sampled. As this
|
|
|
|
effects datardy triggers, hardware buffers and the sysfs
|
|
|
|
direct access interfaces, it may be found in any of the
|
|
|
|
relevant directories. If it effects all of the above
|
|
|
|
then it is to be found in the base device directory as here.

Description of the scan element data storage within the buffer
|
2010-11-23 00:31:16 +01:00
|
|
|
and hence the form in which it is read from user-space.
|
|
|
|
Form is [s|u]bits/storagebits[>>shift]. 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 a64 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.
