git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging Pull staging / IIO driver updates from Greg KH: "Here is the big staging and iio driver update for 5.2-rc1. Lots of tiny fixes all over the staging and IIO driver trees here, along with some new IIO drivers. The "counter" subsystem was added in here as well, as it is needed by the IIO drivers and subsystem. Also we ended up deleting two drivers, making this pull request remove a few hundred thousand lines of code, always a nice thing to see. Both of the drivers removed have been replaced with "real" drivers in their various subsystem directories, and they will be coming to you from those locations during this merge window. There are some core vt/selection changes in here, that was due to some cleanups needed for the speakup fixes. Those have all been acked by the various subsystem maintainers (i.e. me), so those are ok. We also added a few new drivers, for some odd hardware, giving new developers plenty to work on with basic coding style cleanups to come in the near future. Other than that, nothing unusual here. All of these have been in linux-next for a while with no reported issues, other than an odd gcc warning for one of the new drivers that should be fixed up soon" [ I fixed up the warning myself - Linus ] * tag 'staging-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging: (663 commits) staging: kpc2000: kpc_spi: Fix build error for {read,write}q Staging: rtl8192e: Remove extra space before break statement Staging: rtl8192u: ieee80211: Fix if-else indentation warning Staging: rtl8192u: ieee80211: Fix indentation errors by removing extra spaces staging: most: cdev: fix chrdev_region leak in mod_exit staging: wlan-ng: Fix improper SPDX comment style staging: rtl8192u: ieee80211: Resolve ERROR reported by checkpatch staging: vc04_services: bcm2835-camera: Compress two lines into one line staging: rtl8723bs: core: Use !x in place of NULL comparison. staging: rtl8723bs: core: Prefer using the BIT Macro. staging: fieldbus: anybus-s: fix wait_for_completion_timeout return handling staging: kpc2000: fix up build problems with readq() staging: rtlwifi: move remaining phydm .h files staging: rtlwifi: strip down phydm .h files staging: rtlwifi: delete the staging driver staging: fieldbus: anybus-s: rename bus id field to avoid confusion staging: fieldbus: anybus-s: keep device bus id in bus endianness Staging: sm750fb: Change *array into *const array staging: rtl8192u: ieee80211: Fix spelling mistake staging: rtl8192u: ieee80211: Replace bit shifting with BIT macro ...
2019-05-07Merge tag 'pidfd-v5.2-rc1' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux Pull pidfd updates from Christian Brauner: "This patchset makes it possible to retrieve pidfds at process creation time by introducing the new flag CLONE_PIDFD to the clone() system call. Linus originally suggested to implement this as a new flag to clone() instead of making it a separate system call. After a thorough review from Oleg CLONE_PIDFD returns pidfds in the parent_tidptr argument. This means we can give back the associated pid and the pidfd at the same time. Access to process metadata information thus becomes rather trivial. As has been agreed, CLONE_PIDFD creates file descriptors based on anonymous inodes similar to the new mount api. They are made unconditional by this patchset as they are now needed by core kernel code (vfs, pidfd) even more than they already were before (timerfd, signalfd, io_uring, epoll etc.). The core patchset is rather small. The bulky looking changelist is caused by David's very simple changes to Kconfig to make anon inodes unconditional. A pidfd comes with additional information in fdinfo if the kernel supports procfs. The fdinfo file contains the pid of the process in the callers pid namespace in the same format as the procfs status file, i.e. "Pid:\t%d". To remove worries about missing metadata access this patchset comes with a sample/test program that illustrates how a combination of CLONE_PIDFD and pidfd_send_signal() can be used to gain race-free access to process metadata through /proc/<pid>. Further work based on this patchset has been done by Joel. His work makes pidfds pollable. It finished too late for this merge window. I would prefer to have it sitting in linux-next for a while and send it for inclusion during the 5.3 merge window" * tag 'pidfd-v5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: samples: show race-free pidfd metadata access signal: support CLONE_PIDFD with pidfd_send_signal clone: add CLONE_PIDFD Make anon_inodes unconditional

2019-04-25counter: 104-quad-8: Add Generic Counter interface supportWilliam Breathitt Gray
This patch adds support for the Generic Counter interface to the 104-QUAD-8 driver. The existing 104-QUAD-8 device interface should not be affected by this patch; all changes are intended as supplemental additions as perceived by the user. Generic Counter Counts are created for the eight quadrature channel counts, as well as their respective quadrature A and B Signals (which are associated via respective Synapse structures) and respective index Signals. The new Generic Counter interface sysfs attributes are intended to expose the same functionality and data available via the existing 104-QUAD-8 IIO device interface; the Generic Counter interface serves to provide the respective functionality and data in a standard way expected of counter devices.

2019-04-14iio: adc: ad7616: Add support for AD7616 ADCBeniamin Bia
The AD7616 is a 12-bit ADC with 16 channels. The AD7616 can be configured to work in hardware mode by controlling it via gpio pins and read data via spi. No support for software mode yet, but it is a work in progress. This device requires a reset in order to update oversampling, so chip info has got a new attribute to mark this. The current assumption that this driver makes for AD7616, is that it's working in Hardware Mode with Serial, Burst and Sequencer modes activated. To activate them, following pins must be pulled high: -SER/PAR -SEQEN And following must be pulled low: -WR/BURST -DB4/SEQEN Datasheets: Link: https://www.analog.com/media/en/technical-documentation/data-sheets/ad7616.pdf Signed-off-by: Beniamin Bia <beniamin.bia@analog.com> Signed-off-by: Alexandru Ardelean <alexandru.ardelean@analog.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2019-04-14iio: adc: ad7606: Move oversampling options in chip info and rework *_avail ↵Stefan Popa
attributes Available oversampling ratios and scales can be shown by calling a common ad7606_show_avail function which takes as parameters the array which stores the values, together with the size of the array. Oversampling options are now defined in chip info structure and they are loaded at probe. Has_Oversampling attribute was removed because oversampling_num was added and it is not needed anymore. The purpose of this patch is to deal with the scale_avail and oversampling_avail arrays in a generic way. This makes it easier to add support for new devices which will work with different scales and oversampling ratios. It is also an intermediate step for adding support for ad7616 which has different oversampling sampling ratios available.

2019-04-04iio: ad_sigma_delta: Properly handle SPI bus locking vs CS assertionLars-Peter Clausen
For devices from the SigmaDelta family we need to keep CS low when doing a conversion, since the device will use the MISO line as a interrupt to indicate that the conversion is complete. This is why the driver locks the SPI bus and when the SPI bus is locked keeps as long as a conversion is going on. The current implementation gets one small detail wrong though. CS is only de-asserted after the SPI bus is unlocked. This means it is possible for a different SPI device on the same bus to send a message which would be wrongfully be addressed to the SigmaDelta device as well. Make sure that the last SPI transfer that is done while holding the SPI bus lock de-asserts the CS signal.
