Revert "HACK: libsensors: Initial attempt at MotionApps 5.1 for MPU6050 + AKM8975"
Need to revert this.
The new iio hal breaks the build for other devices.
I first need understand the dependencies.
This reverts commit c0aca57ba5869c883bb8ce2dd1d90db86c8212f9.

-protective as the terms of this Section. Licensee will exercise at least the
-same amount of diligence in preserving the secrecy of the Confidential
-Information as it uses in preserving the secrecy of its own most valuable
-confidential information, but in no event less than reasonable diligence.
-Information shall not be considered Confidential Information if and to the
-extent that it: (i) was in the public domain at the time it was disclosed or
-has entered the public domain through no fault of Licensee; (ii) was known to
-Licensee, without restriction, at the time of disclosure as proven by the
-files of Licensee in existence at the time of disclosure; or (iii) becomes
-known to Licensee, without restriction, from a source other than InvenSense

-SPECIAL, OR CONSEQUENTIAL DAMAGES, HOWEVER CAUSED AND ON ANY THEORY OF
-LIABILITY, WHETHER FOR BREACH OF CONTRACT, TORT (INCLUDING NEGLIGENCE) OR
-OTHERWISE, ARISING OUT OF THIS AGREEMENT, INCLUDING BUT NOT LIMITED TO LOSS
-OF PROFITS, EVEN IF SUCH PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES. IN NO EVENT WILL INVENSENSE'S LIABILITY WHETHER IN CONTRACT, TORT
-(INCLUDING NEGLIGENCE), OR OTHERWISE, EXCEED THE AMOUNT PAID BY LICENSEE FOR
-SOFTWARE UNDER THIS AGREEMENT. THESE LIMITATIONS SHALL APPLY NOTWITHSTANDING
-ANY FAILURE OF ESSENTIAL PURPOSE OF ANY LIMITED REMEDY.
-
-7. MISCELLANEOUS
-
-7.1. Export Regulations. YOU UNDERSTAND AND AGREE THAT THE SOFTWARE IS
-SUBJECT TO UNITED STATES AND OTHER APPLICABLE EXPORT-RELATED LAWS AND
-REGULATIONS AND THAT YOU MAY NOT EXPORT, RE-EXPORT OR TRANSFER THE SOFTWARE

-benefit of the parties and their respective successors and assigns, provided,
-however that Licensee may not assign this Agreement or any rights or
-obligation hereunder, directly or indirectly, by operation of law or
-otherwise, without the prior written consent of InvenSense, and any such
-attempted assignment shall be void. Notwithstanding the foregoing, Licensee
-may assign this Agreement to a successor to all or substantially all of its
-business or assets to which this Agreement relates that is not a competitor
-of InvenSense.
-
-7.3. Governing Law; Venue. This Agreement shall be governed by the laws of
-California without regard to any conflict-of-laws rules, and the United
-Nations Convention on Contracts for the International Sale of Goods is hereby
-excluded. The sole jurisdiction and venue for actions related to the subject
-matter hereof shall be the state and federal courts located in the County of
-Orange, California, and both parties hereby consent to such jurisdiction and
-venue.
-
-7.4. Severability. All terms and provisions of this Agreement shall, if
-possible, be construed in a manner which makes them valid, but in the event
-any term or provision of this Agreement is found by a court of competent
-jurisdiction to be illegal or unenforceable, the validity or enforceability
-of the remainder of this Agreement shall not be affected if the illegal or
-unenforceable provision does not materially affect the intent of this
-Agreement. If the illegal or unenforceable provision materially affects the
-intent of the parties to this Agreement, this Agreement shall become
-terminated.
-
-7.5. Equitable Relief. Licensee hereby acknowledges that its breach of this
-Agreement would cause irreparable harm and significant injury to InvenSense
-that may be difficult to ascertain and that a remedy at law would be
-inadequate. Accordingly, Licensee agrees that InvenSense shall have the right
-to seek and obtain immediate injunctive relief to enforce obligations under
-the Agreement in addition to any other rights and remedies it may have.
-
-7.6. Waiver. The waiver of, or failure to enforce, any breach or default
-hereunder shall not constitute the waiver of any other or subsequent breach
-or default.
-
-7.7. Entire Agreement. This Agreement sets forth the entire Agreement
-between the parties and supersedes any and all prior proposals, agreements
-and representations between them, whether written or oral concerning the
-Software. This Agreement may be changed only by mutual agreement of the
-parties in writing.

+ *
+ * The available data sets are:
+ *
+ * - INV_ROTATION_MATRIX :
+ * Returns an array of nine data points representing the rotation
+ * matrix generated from all available sensors.
+ * This requires that ML_SENSOR_FUSION be enabled.
+ * The array format will be R11, R12, R13, R21, R22, R23, R31, R32,
+ * R33, representing the matrix:
+ * <center>R11 R12 R13</center>
+ * <center>R21 R22 R23</center>
+ * <center>R31 R32 R33</center>
+ * <b>Please refer to the "9-Axis Sensor Fusion Application Note" document,
+ * section 7 "Sensor Fusion Output", for details regarding rotation
+ * matrix output</b>.
+ *
+ * - INV_QUATERNION :
+ * Returns an array of four data points representing the quaternion
+ * generated from all available sensors.
+ * This requires that ML_SENSOR_FUSION be enabled.
+ *
+ * - INV_EULER_ANGLES_X :
+ * Returns an array of three data points representing roll, pitch, and
+ * yaw using the X axis of the gyroscope, accelerometer, and compass as
+ * reference axis.
+ * This is typically the convention used for mobile devices where the X
+ * axis is the width of the screen, Y axis is the height, and Z the
+ * depth. In this case roll is defined as the rotation around the X
+ * axis of the device.
+ * The euler angles convention for this output is the following:
+ * <TABLE>
+ * <TR><TD><b>EULER ANGLE</b></TD><TD><b>ROTATION AROUND</b></TD></TR>
+ * <TR><TD>roll </TD><TD>X axis </TD></TR>
+ * <TR><TD>pitch </TD><TD>Y axis </TD></TR>
+ * <TR><TD>yaw </TD><TD>Z axis </TD></TR>
+ * </TABLE>
+ * INV_EULER_ANGLES_X corresponds to the INV_EULER_ANGLES output and is
+ * therefore the default convention.
+ *
+ * - INV_EULER_ANGLES_Y :
+ * Returns an array of three data points representing roll, pitch, and
+ * yaw using the Y axis of the gyroscope, accelerometer, and compass as
+ * reference axis.
+ * This convention is typically used in augmented reality applications,
+ * where roll is defined as the rotation around the axis along the
+ * height of the screen of a mobile device, namely the Y axis.
+ * The euler angles convention for this output is the following:
+ * <TABLE>
+ * <TR><TD><b>EULER ANGLE</b></TD><TD><b>ROTATION AROUND</b></TD></TR>
+ * <TR><TD>roll </TD><TD>Y axis </TD></TR>
+ * <TR><TD>pitch </TD><TD>X axis </TD></TR>
+ * <TR><TD>yaw </TD><TD>Z axis </TD></TR>
+ * </TABLE>
+ *
+ * - INV_EULER_ANGLES_Z :
+ * Returns an array of three data points representing roll, pitch, and
+ * yaw using the Z axis of the gyroscope, accelerometer, and compass as
+ * reference axis.
+ * This convention is mostly used in application involving the use
+ * of a camera, typically placed on the back of a mobile device, that
+ * is along the Z axis. In this convention roll is defined as the
+ * rotation around the Z axis.
+ * The euler angles convention for this output is the following:
+ * <TABLE>
+ * <TR><TD><b>EULER ANGLE</b></TD><TD><b>ROTATION AROUND</b></TD></TR>
+ * <TR><TD>roll </TD><TD>Z axis </TD></TR>
+ * <TR><TD>pitch </TD><TD>X axis </TD></TR>
+ * <TR><TD>yaw </TD><TD>Y axis </TD></TR>
+ * </TABLE>
+ *
+ * - INV_EULER_ANGLES :
+ * Returns an array of three data points representing roll, pitch, and
+ * yaw corresponding to the INV_EULER_ANGLES_X output and it is
+ * therefore the default convention for Euler angles.
+ * Please refer to the INV_EULER_ANGLES_X for a detailed description.
+ *
+ * - INV_LINEAR_ACCELERATION :
+ * Returns an array of three data points representing the linear
+ * acceleration as derived from both gyroscopes and accelerometers.
+ * This requires that ML_SENSOR_FUSION be enabled.
+ *
+ * - INV_LINEAR_ACCELERATION_WORLD :
+ * Returns an array of three data points representing the linear
+ * acceleration in world coordinates, as derived from both gyroscopes
+ * and accelerometers.
+ * This requires that ML_SENSOR_FUSION be enabled.
+ *
+ * - INV_GRAVITY :
+ * Returns an array of three data points representing the direction
+ * of gravity in body coordinates, as derived from both gyroscopes
+ * and accelerometers.
+ * This requires that ML_SENSOR_FUSION be enabled.
+ *
+ * - INV_ANGULAR_VELOCITY :
+ * Returns an array of three data points representing the angular
+ * velocity as derived from <b>both</b> gyroscopes and accelerometers.
+ * This requires that ML_SENSOR_FUSION be enabled, to fuse data from
+ * the gyroscope and accelerometer device, appropriately scaled and
+ * oriented according to the respective mounting matrices.
+ *
+ * - INV_RAW_DATA :
+ * Returns an array of nine data points representing raw sensor data
+ * of the gyroscope X, Y, Z, accelerometer X, Y, Z, and
+ * compass X, Y, Z values.
+ * These values are not scaled and come out directly from the devices'
+ * sensor data output. In case of accelerometers with lower output
+ * resolution, e.g 8-bit, the sensor data is scaled up to match the
+ * 2^14 = 1 gee typical representation for a +/- 2 gee full scale
+ * range.
+ *
+ * - INV_GYROS :
+ * Returns an array of three data points representing the X gyroscope,
+ * Y gyroscope, and Z gyroscope values.
+ * The values are not sensor fused with other sensor types data but

+ * The INV_GYROS values are scaled to ensure 1 dps corresponds to 2^16
+ * codes.
+ *
+ * - INV_ACCELS :
+ * Returns an array of three data points representing the X
+ * accelerometer, Y accelerometer, and Z accelerometer values.
+ * The values are not sensor fused with other sensor types data but

+ * codes.
+ *
+ * - INV_MAGNETOMETER :
+ * Returns an array of three data points representing the compass
+ * X, Y, and Z values.
+ * The values are not sensor fused with other sensor types data but
+ * reflect the orientation from the mounting matrices in use.
+ * The INV_MAGNETOMETER values are scaled to ensure 1 micro Tesla (uT)
+ * corresponds to 2^16 codes.
+ *
+ * - INV_GYRO_BIAS :
+ * Returns an array of three data points representing the gyroscope
+ * biases.
+ *
+ * - INV_ACCEL_BIAS :
+ * Returns an array of three data points representing the
+ * accelerometer biases.

+ * Returns an array of three data points representing the compass
+ * biases.
+ *
+ * - INV_GYRO_CALIBRATION_MATRIX :
+ * Returns an array of nine data points representing the calibration
+ * matrix for the gyroscopes:
+ * <center>C11 C12 C13</center>

+ *
+ * - INV_PRESSURE :
+ * Returns a single value representing the pressure in Pascal
+ *
+ * - INV_HEADING :
+ * Returns a single number representing the heading of the device
+ * relative to the Earth, in which 0 represents North, 90 degrees
+ * represents East, and so on.
+ * The heading is defined as the direction of the +Y axis if the Y
+ * axis is horizontal, and otherwise the direction of the -Z axis.
+ *
+ * - INV_MAG_BIAS_ERROR :
+ * Returns an array of three numbers representing the current estimated
+ * error in the compass biases. These numbers are unitless and serve
+ * as rough estimates in which numbers less than 100 typically represent
+ * reasonably well calibrated compass axes.
+ *
+ * @pre MLDmpOpen() or MLDmpPedometerStandAloneOpen()

+
+/**
+ * @defgroup MLDMP
+ * @brief
+ *
+ * These are the top level functions that define how to load the MPL. In order
+ * to use most of the features, the DMP must be loaded with some code. The
+ * loading procedure takes place when calling inv_dmp_open with a given DMP set
+ * function, after having open the serial communication with the device via
+ * inv_serial_start().
+ * The DMP set function will load the DMP memory and enable a certain
+ * set of features.
+ *
+ * First select a DMP version from one of the released DMP sets.
+ * These could be:
+ * - DMP default to load and use the default DMP code featuring pedometer,
+ * gestures, and orientation. Use inv_dmp_open().
+ * - DMP pedometer stand-alone to load and use the standalone pedometer
+ * implementation. Use inv_open_low_power_pedometer().
+ * <!-- - DMP EIS ... Use inv_eis_open_dmp(). -->
+ *
+ * After inv_dmp_openXXX any number of appropriate initialization and configuration
+ * routines can be called. Each one of these routines will return an error code
+ * and will check to make sure that it is compatible with the the DMP version
+ * selected during the call to inv_dmp_open.
+ *
+ * Once the configuration is complete, make a call to inv_dmp_start(). This will
+ * finally turn on the DMP and run the code previously loaded.
+ *
+ * While the DMP is running, all data fetching, polling or other functions can
+ * be called and will return valid data. Some parameteres can be changed while
+ * the DMP is runing, while others cannot. Therefore it is important to always
+ * check the return code of each function. Check the error code list in mltypes
+ * to know what each returned error corresponds to.
+ *
+ * When no more motion processing is required, the library can be shut down and
+ * the DMP turned off. We can do that by calling inv_dmp_close(). Note that
+ * inv_dmp_close() will not close the serial communication automatically, which will
+ * remain open an active, in case another module needs to be loaded instead.
+ * If the intention is shutting down the MPL as well, an explicit call to
+ * inv_serial_stop() following inv_dmp_close() has to be made.
+ *
+ * The MPL additionally implements a basic state machine, whose purpose is to
+ * give feedback to the user on whether he is following all the required
+ * initialization steps. If an anomalous transition is detected, the user will
+ * be warned by a terminal message with the format:
+ *
+ * <tt>"Error : illegal state transition from STATE_1 to STATE_3"</tt>
