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The current model of Ion heap registration is based on the outdated model of board files.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:

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

Gstreamer's v4l2src reacted poorly to certain outputs from the bcm2835 video driver's ioctl ops function vidioc_enum_framesizes, so a workaround was created that could be activated by user input. This workaround would replace the driver's ioctl ops struct with another, similar struct--only with no function pointed to by vidioc_enum_framesizes. With no response, gstreamer would attempt to continue with some default settings that happened to work better. However, this bug has been fixed in gstreamer since 2014, so we shouldn't include this workaround in the stable version of the driver. Signed-off-by:

Driver SDIO code uses helper functions to do IO to the SDIO device. Current helpers handle IO of a single byte as well as multi-byte. Driver predominately uses single byte IO. If the common case is made simple it simplifies the whole driver. The common case can be made simple by splitting the multi-byte and single byte calls into separate functions, i.e 4 functions in total, read single byte, read multi-byte, write single byte, write multi-byte. Also, we need to handle the debug code. Currently debug calls after read/write fail access the IO buffer. This buffer, at best, does not hold useful data on the error path, at worst is uninitialized and holds garbage. Split read/write helper functions into two functions each, one for single byte IO and one for multi-byte IO. Fix all call sites. Do not change the program logic. Signed-off-by:

Currently driver uses a hardware information struct description to group some SDIO related functionality (work, work queue, sdio private data pointer). This structure is then embedded in the device private data structure. Having nested structures described in different header files means that to view the device private data programmers must open two header files. This structure could be embedded anonymously in the device private data and achieve the same result (grouping of function specific to SDIO) without the need to open multiple headers. However, the SDIO private data structure already has various different data and pointers, adding the embedded structure adds little extra meaning and lengthens all the dereferences throughout the driver, often meaning addition line breaks and braces. We can increase readability and reduce code complexity by moving the hardware information data and pointers to directly be within the device private data structure description. While preparing for this refactoring it was noted that the identifier currently used for the delayed work is 'rw_wq', this is confusing since the 'wq' suffix typically means 'work queue'. This identifier would be more meaningful if it used the suffix 'dwork' as does the declaration of queue_delayed_work() (include/linux/workqueue.h). The identifier for the work queue is currently 'ks7010sdio_wq'. This identifier can be shortened without loss of meaning because there is only one work queue within the driver. Identifier 'wq' is typical within in-tree driver code and aptly describes the pointer. Current pointer to the SDIO private data is identified by 'sdio_card', this is sufficiently meaningful from within the hw_info structure but once the hw_info_t structure is removed the pointer would be better to have a prefix appended to it to retain the prior level of meaning. Move members from struct hw_info_t to struct ks_wlan_private. Rename identifiers; struct delayed_work pointer 'rw_wq' to 'rw_dwork'. struct workqueue_struct pointer 'ks7010sdio_wq' to 'wq'. struct ks_sdio_card pointer 'sdio_card' to 'ks_sdio_card'. Remove structure description hw_info_t. Fix init/destroy calls. Fix all call sites, SDIO private data access calls, and queuing calls. Signed-off-by:

Currently a pointer to the tasklet_struct used for bottom half processing on the receive path is within the hw_info_t structure. This structure is then embedded in the device private data structure. Having the tasklet_struct nested does not add meaning to the device private data, device private data already (and typically) has various data relating to the device, there is no real need to separate the tasklet_struct to a SDIO specific structure. While not adding allot of extra meaning having the nested structure means the programmer must open two header files to read the description of the device private data, the code would be easier to read if the device private data struct description was not spread over two files. Move tasklet_struct out of sdio header file and into the device private data structure description. Signed-off-by:
