Merge tag 'iio-for-4.8b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Second round of new iio device support, features and cleanups in the 4.8 cycle Firstly some contact detail updates: * NXP took over freescale. Update the mma8452 header to reflect this. * Martin Kepplinger email address change in mma8452 header. * Adriana Reus has changed email address. Update .mailmap. * Matt Ranostay has changed email address. Update .mailmap. New Device Support * max1363 - add the missing i2c_device_ids for a couple of parts so they can actually be used. * ms5867 - add device ids for ms5805 and ms5837 parts. New Features * ad5755 - DT support. This one was a bit controversial and under review for a long time. Still no one could come up with a better solution. * stx104 - add gpio support * ti-adc081c - Add ACPI device ID matching. Core changes * Refuse to register triggers with duplicate names. There is no way to distinguish between them so this makes no sense. A few drivers do not generate unique names for each instance of the device present. We can't fix this without changing ABI so leave them and wait for someone to actually take the rare step of two identical accelerometers on the same board. * buffer-dma - use ARRAY_SIZE in a few appropriate locations. Tools * Fix the fact that the --trigger-num option in generic_buffer didn't allow 0 which is perfectly valid in the ABI. Cleanups * as3935 - improve error reporting. - remove redundant zeroing of a field in iio_priv. * gp2ap020a00f - use the iio_device_claim_*_mode helpers rather than open coding locking around mode changes. * isl29125 - use the iio_device_claim_*_mode helpers rather than open coding locking. * lidar - use the iio_device_claim_*_mode helpers rather than open coding locking. * mma8452 - more detail in devices supported description in comments (addresses and similar) * sca3000 - add a missing error check. * tcs3414 - use the iio_device_claim_*_mode helpers rather than open coding locking. * tcs3472 - use the iio_device_claim_*_mode helpers rather than open coding locking.

gcc warns about a potentially uninitialized variable use in as3935_event_work: drivers/iio/proximity/as3935.c: In function ‘as3935_event_work’: drivers/iio/proximity/as3935.c:231:6: error: ‘val’ may be used uninitialized in this function [-Werror=maybe-uninitialized] This case specifically happens when spi_w8r8() fails with a negative return code. We check all other users of this function except this one. As the error is rather unlikely to happen after the device has already been initialized, this just adds a dev_warn(). Another warning already exists in the same function, but is missing a trailing '\n' character, so I'm fixing that too. Signed-off-by:

The layer abstracting the building of commands and extracting responses is currently based on macros that shift and mask the command fields and requires exposing offset/size values as macro parameters and makes the code harder to read. For clarity and maintainability, instead use an implementation based on mapping the MC command definitions to C structures. These structures contain the hardware command fields (which are naturally-aligned) and individual fields are little-endian ordering (the byte ordering of the hardware). As such, there is no need to perform the conversion between core and hardware (LE) endianness in mc_send_command(), but instead each individual field in a command will be converted separately if needed by the function building the command or extracting the response. This patch does not introduce functional changes, both the hardware ABIs and the APIs exposed for the DPAA2 objects remain the same. Signed-off-by:

For an MSI domain the hwirq is an arbitrary but unique id to identify an interrupt. Previously the hwirq was set to the MSI index of the interrupt, but that only works if there is one DPRC. Additional DPRCs require an expanded namespace. Use both the ICID (which is unique per DPRC) and the MSI index to compose a hwirq value. Signed-off-by:

An mc_io represents a mapped MC portal. Previously, an mc_io was created for the root dprc in fsl_mc_bus_probe() and for child dprcs in dprc_probe(). But the free of that data structure happened in the general bus remove callback. This asymmetry resulted in some bugs due to unwanted destroys of mc_io object in some scenarios (e.g. vfio). Fix this bug by making things symmetric-- mc_io created in fsl_mc_bus_probe() is freed in fsl_mc_bus_remove(). The mc_io created in dprc_probe() is freed in dprc_remove(). Signed-off-by:

The semaphore 'close_exit_sync' does not serve any purpose other than delaying the deregistration of the device which it is trying to protect from shared access. 'up' is called only when a subdevice is closed and not when it is opened. So, the semaphore count only goes up when the device is used. Signed-off-by:
