Hi all, I've pasted the following in directly as diffs of these files are somewhat hard to comment on and it's more or less rewritten. The basic principal here was to move towards cleanly documenting every attribute we have. This involved firstly moving to X Y Z for numeric indexing and adding multiple What: lines to the file to list everything. Basically we want people to be able to grep when they come across an attribute and wonder what it does. There are a few omissions in here at the moment (rot, angl, hyst) but those are mainly because I'm not quite sure what they are and haven't datasheet dived as yet. I have also cut out a few things that we agreed interfaces for but which are not currently used by any drivers (meanperiod for example) A couple of our drivers aren't currently compliant with this spec (including some of mine ;) The other addition that will come is that of inY_thresh_above_en and inY_thresh_below_en. This was suggested in a sensor outside iio that is matching our abi (more or less) and seems a sensible and clear way of handling 'level' type interrupts (that is those that will retrigger if the interrupt is cleared and they are still true). All comments welcome! Lets get this nice and clean once and for all. I haven't rolled in the light sensor attributes as yet, but will look at how simple that is after we have the current content cleaned up. Thanks, Jonathan ... What: /sys/bus/iio/devices/deviceX KernelVersion: 2.6.35 Contact: linux-iio@xxxxxxxxxxxxxxx Description: Hardware chip or device accessed by on communication port. Corresponds to a grouping of sensor channels. X is the IIO index of the device. What: /sys/bus/iio/devices/triggerX KernelVersion: 2.6.35 Contact: linux-iio@xxxxxxxxxxxxxxx Description: An event driven driver of data capture to an in kernel buffer. May be provided by a device driver that also has an IIO device based on hardware generated events (e.g. data ready) or provided by a separate driver for other hardware (e.g. periodic timer, gpio or high resolution timer). Contains trigger type specific elements. These do not generalize well and hence are not documented in this file. X is the IIO index of the trigger. What: /sys/bus/iio/devices/deviceX:buffer KernelVersion: 2.6.35 Contact: linux-iio@xxxxxxxxxxxxxxx Description: Link to /sys/class/iio/deviceX/deviceX:buffer.

What: /sys/bus/iio/devices/deviceX/sampling_frequency KernelVersion: 2.6.35 Contact: linux-iio@xxxxxxxxxxxxxxx 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.

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 transfered 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.

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. -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
