iio: imu: adis16480: Fix acceleration scale factor for adis16480

2017-08-30T08:26:41Z

commit fdd0d32eb95f135041236a6885d9006315aa9a1d upstream. According to the datasheet, the range of the acceleration is [-10 g, + 10 g], so the scale factor should be 10 instead of 5.

iio: imu: inv_mpu6050: add accel lpf setting for chip >= MPU6500

2017-06-03T08:40:40Z

Starting from MPU6500, accelerometer dlpf is set in a separate register named ACCEL_CONFIG_2. Add this new register in the map and set it for the corresponding chips. Signed-off-by: Jean-Baptiste Maneyrol Cc: stable@vger.kernel.org Signed-off-by: Jonathan Cameron

Third set of new device support, cleanups and features for IIO in the 4.12 cycle Somewhat dominated in patch numbers of last of the outreachy application window related patches (they are still coming, despite window being closed which is good to see!) Good set of new drivers as well. New device support * ASPEED ADC - new driver * cpcap PMIC ADC - new driver * hid-humidity - driver for HID compatible humidity sensors. * ltc2497 ADC - new driver * mpu6050 - bring bindings up to date and add trivial support for 9250 * rockchip-saradc - update bindings to cover rk3328 * vl6180 light, proximity and time of flight sensor. - new driver Features * meson-saradc - add calibration Cleanup and minor fixes * ad5504 - constify attribute_group structure - drop casting of void * * ad7150 - replace some shifts of 1 by BIT macro usage * ad7152 - blank lines between function definitions * ad7280a - octal permissions. * ad7606 - replace use of core mlock mutex with a local lock * ad7746 - replace some shifts of 1 by BIT macro usage - function parameter alignment - drop some excessive brackets (introduced in last pull request) * ad7753 - white space cleanup * ad7754 - includes in alphabetical order and groupped appropriately. - change from missuse of internal mlock mutex to using the buffer lock to also protect values during frequency update. * ad779x - constify attribute_group structures * ad9832 - octal permissions * adis16060 - remove use of core mlock mutex in favour of adding a local _spi_write_then_read which can use the local buffer protection lock. - fix naming of above function. * adis16203 - remove locking during reads of calibbias that doesn't protect anything not protected elsewhere. * adis16209 - remove unnecessary braces in single statement if * adis16240 - remove unnecessary braces in single statement if * adt7136 - drop excess blank lines and put some in between functions. * ams-iaq - replace comma with semi colon. Not actual bug, just unusual syntax. * apds9960 - constify attribute group structure * as3935 - constify attribute group structure * bm1750 - constify attribute group structure * cros_ec - devm version of triggered buffer setup to simplify code. * exynos - drop casting of void * * hdc100x - constify attribute_group structure * hid-accel - fix wrong scale for newly introduced gravity sensor. * hts221 - drop casting of void * * hx711 - constify attribute_group structure * imx7d_adc - drop casting of void * * lm35333 - constify attribute_group structure * lsm6dsx - drop casting of void * - hold ODR configuration until enabling to avoid a race condition. * max1027 - drop casting of void * * max11100 - fix a comma where semicolon was intended (no actual bug, just odd) * max1363 - constify attribute_group structure * ms sensors - drop casting of void * * rockchip_saradc - drop casting of void * * sun4i-gpadc - fix missing dependency on THERMAL or presence of stubs (issue only introduced in pervious set) - drop casting of void * * tsl2x7x - fix wrong standard deviation calc. Note these aren't actually used for anything at the moment so bug didn't really matter. - constify attribute group structure. * vf610adc - drop casting of void * * vz89x - replace comma with semicolon. Not actual bug, just odd syntax. * zpa2326 - drop casting of void *

iio: imu: st_lsm6dsx: do not apply ODR configuration in write_raw handler

2017-04-02T13:36:06Z

This patch allows to avoid a transitory that occurs when a given sensor has been already enabled (e.g. gyroscope) and the user is configuring the sample frequency of the other one (e.g. accelerometer). The transitory lasts until the accelerometer is enabled. During that time slice the gyroscope ODR is incorrectly modified as well. At the end of the transitory both sensors work at the right frequency. Fix it introducing st_lsm6dsx_check_odr() routine to check ODR consistency in write_raw handler in order to apply frequency configuration just in st_lsm6dsx_set_odr() Fixes: 290a6ce11d93 (iio: imu: add support to lsm6dsx driver) Signed-off-by: Lorenzo Bianconi Signed-off-by: Jonathan Cameron

iio:imu:mpu6050 add explicit mpu9250 support

2017-04-02T09:12:08Z

The mpu9250 is a SIP containing an mpu6500 and an ak8975. If this was all there was too it there would be no need for explicit handling in the driver. Arguably the bindings would also only reflect the presence of an mpu6500 with the ak8975 hanging off it, as the kernel doesn't care that they are in one package. However, the WHOAMI value changes as well so best to add explicit support. Signed-off-by: Jonathan Cameron

iio: imu: inv_mpu6050: Add OF device ID table

2017-03-19T10:54:43Z

The driver doesn't have a struct of_device_id table but supported devices are registered via Device Trees. This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF.
