<type>Y[_name]_thresh[_(rising|falling)]_hysteresis. 841 If separate attributes exist for the two directions, but 842 direction is not specified for this attribute, then a single 843 hysteresis value applies to both directions. 844 For falling events the hysteresis is added to the _value attribute for 845 this event to get the upper threshold for when the event goes back to 846 normal, for rising events the hysteresis is subtracted from the _value 847 attribute. E.g. if in_voltage0_raw_thresh_rising_value is set to 1200 848 and in_voltage0_raw_thresh_rising_hysteresis is set to 50. The event 849 will get activated once in_voltage0_raw goes above 1200 and will become 850 deactivated again once the value falls below 1150. 851 852What:

This is a rotation matrix which 1600 informs userspace about sensor chip's placement relative to the 1601 main hardware it is mounted on. 1602 Main hardware placement is defined according to the local 1603 reference frame related to the physical quantity the sensor 1604 measures. 1605 Given that the rotation matrix is defined in a board specific 1606 way (platform data and / or device-tree), the main hardware 1607 reference frame definition is left to the implementor's choice 1608 (see below for a magnetometer example). 1609 Applications should apply this rotation matrix to samples so 1610 that when main hardware reference frame is aligned onto local 1611 reference frame, then sensor chip reference frame is also 1612 perfectly aligned with it. 1613 Matrix is a 3x3 unitary matrix and typically looks like 1614 [0, 1, 0; 1, 0, 0; 0, 0, -1]. Identity matrix 1615 [1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and main hardware 1616 are perfectly aligned with each other. 1617 1618 For example, a mounting matrix for a magnetometer sensor informs 1619 userspace about sensor chip's ORIENTATION relative to the main 1620 hardware. 1621 More specifically, main hardware orientation is defined with 1622 respect to the LOCAL EARTH GEOMAGNETIC REFERENCE FRAME where : 1623 * Y is in the ground plane and positive towards magnetic North ; 1624 * X is in the ground plane, perpendicular to the North axis and 1625 positive towards the East ; 1626 * Z is perpendicular to the ground plane and positive upwards. 1627 1628 An implementor might consider that for a hand-held device, a 1629 'natural' orientation would be 'front facing camera at the top'. 1630 The main hardware reference frame could then be described as : 1631 * Y is in the plane of the screen and is positive towards the 1632 top of the screen ; 1633 * X is in the plane of the screen, perpendicular to Y axis, and 1634 positive towards the right hand side of the screen ; 1635 * Z is perpendicular to the screen plane and positive out of the 1636 screen. 1637 Another example for a quadrotor UAV might be : 1638 * Y is in the plane of the propellers and positive towards the 1639 front-view camera; 1640 * X is in the plane of the propellers, perpendicular to Y axis, 1641 and positive towards the starboard side of the UAV ; 1642 * Z is perpendicular to propellers plane and positive upwards. 1643 1644What: /sys/bus/iio/devices/iio:deviceX/in_electricalconductivity_raw 1645KernelVersion: 4.8 1646Contact: linux-iio@vger.kernel.org 1647Description: 1648 Raw (unscaled no offset etc.) electric conductivity reading that 1649 can be processed to siemens per meter. 1650 1651What: /sys/bus/iio/devices/iio:deviceX/in_countY_raw 1652KernelVersion: 4.10 1653Contact: linux-iio@vger.kernel.org 1654Description: 1655 Raw counter device counts from channel Y.
