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. Signed-off-by:

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.

Add system sleep power management support to st_lsm6dsx driver. In particular during suspend phase each sensor is disabled and hw fifo is configured in bypass in order to avoid subsequent I/O operations. The patch has been tested on HiKey board device Signed-off-by:

isl29030 is basically the same chip. The only difference is the chip's first pin. For isl29028 its named ADDR0 and can be used to change the chip's i2c address. For isl29030 on the other hand that pin is named Ials and is an analog current output proportional to ALS/IR. This change is irrelevant for the Linux driver. This has been tested on Motorola Droid 4.

Ensure that when an invalid value in ret or value is found -EINVAL is returned.

Use the local uapi headers to keep in sync with "recently" added enum values like IIO_UVINDEX. Build tested using: $ make -C <kernelsrcdir> tools/iio $ make -C <kernelsrcdir>/tools iio $ make -C <kernelsrcdir>/tools/iio This follows a strategy similar to that used by tools/hv, tools/net and tools/leds among others.

This patch fixes the sensor platform data initialisation for st_pressure and st_accel device drivers. Without this patch, the driver fails to register the sensors when the user removes and re-loads the driver. 1. Unload the kernel modules for st_pressure $ sudo rmmod st_pressure_i2c $ sudo rmmod st_pressure 2. Re-load the driver $ sudo insmod st_pressure $ sudo insmod st_pressure_i2c Signed-off-by:

The sysfs attribute in_proximity_sampling_frequency_available currently shows the values 1 3 5 10 13 20 83 100. These values are supposed to correspond to the sleep values 800 400 200 100 75 50 12.5 0 (all in ms). When passing in a sampling frequency of 3, it actually uses a sleep time of 200ms instead of the expected 400ms value. This patch changes the value shown by this sysfs attribute to use fixed-point numbers so that the correct sampling frequency is shown to the user. This patch also changes the code that updates the proximity sampling frequency to only allow values that are shown in the _available sysfs attribute. The original code showed the value 83 that corresponds to the sleep time 12 ms. The data sheet actually lists 12.5 ms as the sleep time, so the proximity frequency was updated to 80. Signed-off-by:

ion_handle was introduced as an abstraction to represent a reference to a buffer via an ion_client. As frameworks outside of Ion evolved, the dmabuf emerged as the preferred standard for use in the kernel. This has made the ion_handle an unnecessary abstraction and prone to race conditions. ion_client is also now only used internally. We have enough mechanisms for race conditions and leaks already so just drop ion_handle and ion_client. This also includes ripping out most of the debugfs infrastructure since much of that was tied to clients and handles. The debugfs infrastructure was prone to give confusing data (orphaned allocations) so it can be replaced with something better if people actually want it. Signed-off-by:

The current model of Ion heap registration is based on the outdated model of board files. The replacement for board files (devicetree) isn't a good replacement for what Ion wants to do. In actuality, Ion wants to show what memory is available in the system for something else to figure out what to use. Switch to a model where Ion creates its device unconditionally and heaps are registed as available regions. Currently, only system and CMA heaps are converted over to the new model. Carveout and chunk heaps can be converted over when someone wants to figure out how. Signed-off-by:

Several of the Ion ioctls were designed in such a way that they necessitate compat ioctls. We're breaking a bunch of other ABIs and cleaning stuff up anyway so let's follow the ioctl guidelines and clean things up while everyone is busy converting things over anyway. As part of this, also remove the useless alignment field from the allocation structure. Signed-off-by:

Laura Abbott authored
When CMA was first introduced, its primary use was for DMA allocation and the only way to get CMA memory was to call dma_alloc_coherent. This put Ion in an awkward position since there was no device structure readily available and setting one up messed up the coherency model. These days, CMA can be allocated directly from the APIs. Switch to using this model to avoid needing a dummy device. This also mitigates some of the caching problems (e.g. dma_alloc_coherent only returning uncached memory). Signed-off-by:

Merge tag 'iio-fixes-for-4.11e' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Fifth set of IIO fixes for the 4.11 cycle. As these are rather late in the cycle, they may sneak over into 4.12. There is a fix for a regression caused by another fix (hid sensors hardware seems to vary a lot in how various corner cases are handled). * ad7303 - fix channel description. Numeric values were being passed as characters presumably leading to garbage from the userspace interface. * as3935 - the write data macro was wrong so fix it. * bmp280 - incorrect handling of negative values as being unsigned broke humidity calculation. * hid-sensor - Restore the poll and hysteresis values after resume as some hardware doesn't do it. * stm32-trigger - buglet in reading the sampling frequency
