  • 0145b5056   iio/hid-sensors: Fix IIO_CHAN_INFO_RAW returning wrong values for signed numbers ... Browse Code »

    Before this commit sensor_hub_input_attr_get_raw_value() failed to take
    the signedness of 16 and 8 bit values into account, returning e.g.
    65436 instead of -100 for the z-axis reading of an accelerometer.

    This commit adds a new is_signed parameter to the function and makes all
    callers pass the appropriate value for this.

    While at it, this commit also fixes up some neighboring lines where
    statements were needlessly split over 2 lines to improve readability.

  • 50db2cd40   iio: orientation: hid-sensor-rotation: Drop unnecessary static ... Browse Code »

    Drop static on a local variable, when the variable is initialized before
    any possible use. Thus, the static has no benefit.

    The semantic patch that fixes this problem is as follows:
    (http://coccinelle.lip6.fr/)

    //
    @bad exists@
    position p;
    identifier x;

  • 00907c7a3   iio: hid-sensor-rotation: Add geomagnetic orientation sensor hid support. ... Browse Code »

    Geomagnetic orientation(AM) sensor is one kind of orientation 6dof sensor.
    It gives the device rotation in respect to the earth center and the
    magnetic north. The sensor is implemented through use of an accelerometer
    and magnetometer do not use gyroscope. It is a standard HID sensor.

    More information can be found in:
    http://www.usb.org/developers/hidpage/HUTRR59_-_Usages_for_Wearables.pdf

    Geomagnetic orientation(AM) sensor and dev rotation sensor have same
    channel and share channel usage id. So the most of the code for relative
    orientation sensor can be reused.

    Relative orientation(AG) sensor is a 6dof orientation sensor,
    it depends on acceleration and gyroscope sensor data. It gives
    a quaternion describing the orientation of the device relative
    to an initial orientation. It is a standard HID sensor.

  • 8af644a7d   iio: orientation: hid-sensor-rotation: Add PM function (fix non working driver) ... Browse Code »

    This fix makes newer ISH hubs work. Previous ones worked by lucky
    coincidence.

    Rotation sensor function does not work due to miss PM function.
    Add common hid sensor iio pm function for rotation sensor.

    Further clarification from Srinivas:

    If CONFIG_PM is not defined, then this prevents this sensor to
    function. So above commit caused this.

    This sensor was supposed to be always on to trigger wake up in prior
    external hubs. But with the new ISH hub this is not the case.

  • b3f4737d0   HID: hid-sensor-hub: Extend API for async reads ... Browse Code »

    Add additional flag to read in async mode. In this mode the caller will get
    reply via registered callback for capture_sample. Callbacks can be registered
    using sensor_hub_register_callback function. The usage id parameter of the
    capture_sample can be matched with the usage id of the requested attribute.

    Added usage id processing for device rotation. This uses IIO
    interfaces for triggered buffer to present data to user
    mode.This uses HID sensor framework for registering callback
    events from the sensor hub.
    Data is exported to user space in the form of quaternion rotation
