  • 6f174fd31   iio: imu: inv_mpu6050: Add compatibity with MPU6500 ... Browse Code »

    Adding MPU6500 in target list for this driver.

    Description:
    Source
    Document: MPU-6500 Register Map and Descriptions Revision 2.1
    Section 3: Register Map

    This section describes difference in terms device programmability
    between MPU6050 and MPU6500.
    These are different registers, which differs between MPU6050 and
    MPU6500.

    Addr Name
    ---------------------
    1E LP_ACCEL_ODR
    6C PWR_MGMT_2
    77 XA_OFFSET_H
    78 XA_OFFSET_L
    7A YA_OFFSET_H
    7B YA_OFFSET_L
    7D ZA_OFFSET_H
    7E ZA_OFFSET_L

    But the current MPU6050 driver doesn't use registers which are different
    except PWR_MGMT_2. The difference is support of "LP_WAKE_CTRL" at bit6-7
    in MPU6050 mode. In MPU6500 they are not defined.
    In current mpu6050 driver, only values used for this register are for
    standby mode for gyro and accelerometer.
    In both case frequency of wakeups is set to default and not using
    bit 6-7.

    So this driver van as well support MPU6500. In addition MPU6500 can
    run MPU6050 mode by changing device trim settings.

    So changing config comments to allow MPU6500 to use this driver.
    When the driver is enhanced to support more functions, i2c driver
    data INV_MPU6500 or "WHO_AM_I" register can be used to add additional
    functionality.

    2

    A single channel in this driver was using the IIO_ST macro.
    This does not provide a parameter for setting the endianness of
    the channel. Thus this channel will have been reported as whatever
    is the native endianness of the cpu rather than big endian. This
    means it would be incorrect on little endian platforms.

  • 1e9663c62   iio:trigger: Introduce iio_tigger_{set,get}_drvdata ... Browse Code »

    Introduce iio_tigger_{set,get}_drvdata which allows to attach driver specific
    data to a trigger. The functions wrap access to the triggers private_data field
    and all current users are updated to use iio_tigger_{set,get}_drvdata instead of
    directly accessing the private_data field. This is the first step towards
    removing the private_data field from the iio_trigger struct.

    The following coccinelle script has been used to update the drivers:

    @@
    struct iio_trigger *trigger;
    expression priv;
    @@
    -trigger->private_data = priv
    +iio_trigger_set_drv_data(trigger, priv)

    @@
    struct iio_trigger *trigger;
    @@
    -trigger->private_data

    …/iio into staging-next

    Jonathan writes:

    First set of IIO new drivers and cleanup for the 3.10 cycle.

    New stuff

    1) Add OF support for specifying mappings between iio devices and their
    in kernel consumers.
    2) Driver for AD7923 (extra functionality and support for ad7904, ad7914 and
    ad7924 added later in series)
    3) Driver for Exynos adc (dt suppor for phy added later in series).
    4) Make iio_push_event save IRQ context - necessary if it is to be used
    within an interrupt handler. Users of this functionality to follow.
    5) For iio use the device tree node name to provide the hwmon name attribute
    if available.

    Removal and moves out of staging

    1) Drop the adt7410 driver from IIO now that there is a hmwon driver with
    equivalent support. This device is very much targeted at hardware
    monitoring so hwmon is a more appropriate host for the driver.
    2) Move iio_hwmon driver to drivers/hwmon.

    Cleanups

    1) Minor cleanup in ST common library.
    2) Large set of patches to break the info_mask element which previously used
    odd and even bits to specify if a channel attribute was either shared across
    similar channels or specific to only one. Now we have two bitmaps, one for
    those parameters that are specific to this channel and one for those shared
    by all channels with the same type as this one. This has no effect on the
    userspace abi. It simplifies the core code and provides more space for new
    channel parameters. It has been on the todo list for a long time!

    channels, three magnetometer channels, one temperature channels and one
    barometric pressure channel.

  • 7ba8a04dc   iio:adis16400: Add support for the 52.85 Hz base sampling rate ... Browse Code »

    The adis16400 and similar have two different base sampling rate available, from
    which the actual sampling rate is derived. 1638 Hz and 52.85 Hz, switching to
    the lower base sampling rate allows to support lower sampling rates.

    This patch adds support for switching to the lower base sampling rate if the
    requested sampling frequency is outside of the range which can be supported by
    the higher base sampling rate.

    The function which is used to read the current sampling rate already has support
    for the lower sampling rate, so no changes are required there.

    Smatch complains that snprintf() returns the number of characters,
    not counting the NUL terminator, which *would* have been printed if
    there were enough space. In other words the return value could be more
    than sizeof(buf).

    In this case, we are printing something like "ff.ff\n" which is at most
    6 characters and a NUL so that's not an issue. I changed snprintf() to
    scnprintf() to silence the warning.

    But since the buffer doesn't include space for the NUL terminator, we
    need to make it bigger or the "\n" will be truncated off.
