Merge tag 'iio-for-5.4b-take3' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Second set of new device support, cleanups and features for IIO in the 5.4 cycle Revised pull request to fix up a missing Signed-off-by and roll in a fix in the lsm9ds1 support after I broke it when applying. Revised again because the fix changed a hash meaning a fix that previously followed it now had the wrong fixes tag. A few fixes in here that could have gone a faster path but aren't quite worth the rush for 5.3. New device support * ad7606 - Support the ad7606b which adds a software controlled mode alongside the pin controlled only approach of the ad7606. Including dt-bindings. * lsm6dsx - Add support for the gyro and accelerometer part of the lsm9ds1 which is a compound device also including a magnetometer (st_sensors driver). Includes bindings and precursor rework of the driver. Features * ad7192 - Add support for low pass filter control. - DT binding docs. Cleanups and minor fixes * MAINTAINERS - Fix a typo in a path. - Add entry for ad7606 * ad5380 - Fix a failure to dereference a pointer before atempting to assign the value. * ad7192 - Drop platform data as not used in mainline and we now have full DT bindings. * ad7606 - YAML conversion for dt-bindings. * adis16240 - Rework write_raw to make it more readable using GENMASK. * adis16460 - Fix and issue with an unsigned variable holding potential negatives. * cros_ec - Fix missing default of calibration vector so that we get 'something' before calibration is complete on a given axis. * hid-sensors - Use int_pow instead of opencoding. * isl29501 - rename dt-binding docs to include renesas inline with other renesas parts and general current convention. * kxcjk1013 - Improve comments on the 'unusual' ACPI ids used to identify which sensor is which in certain laptops. * lsm6dsx - Add one bit to the fifo status masks for a number of parts. - Drop a reserved entry from the sensitivity values to tidy up interface. - Use core conversion macro from G to m/s^2 for lsm9ds1 to make it easier to relate to the datasheet and consistent with other parts supported. * max1027 - Use device managed APIs to avoid manual error handling and cleanup. * rfd77402 - Typo in Kconfig help. * sc27xx - Switch to polling mode from interrupts as interrupt handling typically to slow for very short sleeps. * st-sensors - Fix some missing selects for regmap. * tools - Add a .gitignore containing the binary outputs. * tag 'iio-for-5.4b-take3' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (27 commits) iio: imu: st_lsm6dsx: rely on IIO_G_TO_M_S_2 for gain definition for LSM9DS1 iio: imu: st_lsm6dsx: remove invalid gain value for LSM9DS1 iio: cros_ec: set calibscale for 3d MEMS to unit vector iio: dac: ad5380: fix incorrect assignment to val iio: imu: st_lsm6dsx: Fix FIFO diff mask for tagged fifo dt-bindings: iio: imu: st_lsm6dsx: add lsm9ds1 device bindings iio: imu: st_lsm6dsx: add support for accel/gyro unit of lsm9ds1 iio: imu: st_lsm6dsx: move register definitions to sensor_settings struct iio: imu: st_lsm6dsx: introduce update_fifo function pointer dt-bindings: iio: light: isl29501: Rename bindings documentation file Kconfig: Fix the reference to the RFD77402 ToF sensor in the 'help' section iio: st_sensors: Fix build error dt-bindings: iio: adc: Add AD7606B ADC documentation dt-bindings: iio: adc: Migrate AD7606 documentation to yaml MAINTAINERS: Add Beniamin Bia for AD7606 driver iio: adc: ad7606: Add support for AD7606B ADC tools: iio: add .gitignore iio: adc: sc27xx: Change to polling mode to read data iio: hid-sensor-attributes: Convert to use int_pow() iio: adc: max1027: Use device-managed APIs ...

Note the binding is st,lsm9ds1-imu. This device is effectively two separate devices in the same package. (separate addreses, chip selects etc) The magnetometer is already supported as lsm9ds1-mag. imu may not be the best name but it's the best that anyone has yet come up with for a gyro and accel part.

The LSM9DS1's accelerometer / gyroscope unit and it's magnetometer (separately supported in iio/magnetometer/st_magn*) are located on a separate i2c addresses on the bus. For the datasheet, see https://www.st.com/resource/en/datasheet/lsm9ds1.pdf Treat it just like the LSM6* devices and, despite it's name, hook it up to the st_lsm6dsx driver, using it's basic functionality. accelerometer and gyroscope are not independently clocked. It runs at the gyro frequencies if both are enabled, see chapter 7.12 of the datasheet. We could have handled this as a single IIO device but we have split it up to be more consistent with the other more flexible devices. Despite supporting and testing the LSM9DS1, we call the gyro channels iio_chan_spec struct "st_lsm6ds0_gyro_channels" because the register description is equal. This suggests that supporting LSM6DS0 should be trivial to do. Signed-off-by:

The problem is in gb_lights_request_handler(). If we get a request to change the config then we release the light with gb_lights_light_release() and re-allocated it. However, if the allocation fails part way through then we call gb_lights_light_release() again. This can lead to a couple different double frees where we haven't cleared out the original values: gb_lights_light_v4l2_unregister(light); ... kfree(light->channels); kfree(light->name); I also made a small change to how we set "light->channels_count = 0;". The original code handled this part fine and did not cause a use after free but it was sort of complicated to read. Fixes: 2870b52b ("greybus: lights: add lights implementation") Signed-off-by:

As Joe Perches suggested [1], err = bio_add_page(bio, page, PAGE_SIZE, 0); - if (unlikely(err != PAGE_SIZE)) { + if (err != PAGE_SIZE) { err = -EFAULT; goto err_out; } The initial assignment to err is odd as it's not actually an error value -E<FOO> but a int size from a unsigned int len. Here the return is either 0 or PAGE_SIZE. This would be more legible to me as: if (bio_add_page(bio, page, PAGE_SIZE, 0) != PAGE_SIZE) { err = -EFAULT; goto err_out; } [1] https://lore.kernel.org/r/74c4784319b40deabfbaea92468f7e3ef44f1c96.camel@perches.com/Signed-off-by:Gao Xiang <gaoxiang25@huawei.com> Link: https://lore.kernel.org/r/20190829171741.225219-1-gaoxiang25@huawei.comSigned-off-by:

Before moving greybus core out of staging and moving header files to include/linux some greybus header files were missing the necessary includes.

With the advent of a recent Google Summer of Code project, and a number of new devices in the works from various companies, it is time to get the core greybus code out of staging as it really is going to be with us for a while.
