2019-05-11iio: adc: ti-ads8688: fix timestamp is not updated in bufferSean Nyekjaer1-1/+1
When using the hrtimer iio trigger timestamp isn't updated. If we use iio_get_time_ns it is updated correctly.

2019-05-11iio: dac: ds4422/ds4424 fix chip verificationRuslan Babayev1-1/+1
The ds4424_get_value function takes channel number as it's 3rd argument and translates it internally into I2C address using DS4424_DAC_ADDR macro. The caller ds4424_verify_chip was passing an already translated I2C address as its last argument.

2019-05-11iio: stmpe-adc: Reset possible interruptsPhilippe Schenker1-0/+5
Clear any interrupt that still is on the device on every channel this driver is activated for in probe and specific channels in the timeout handler. Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
2019-05-11iio: stmpe-adc: Use wait_for_completion_timeoutPhilippe Schenker1-12/+4
Use wait_for_completion_timeout instead of wait_for_completion_interuptible_timeout. The interruptible variant gets constantly interrupted if a user program is compiled with the -pg option. The killable variant was not used due to the fact that a second program, reading on this device, that gets killed is then also killing that wait.

2019-05-11iio: stmpe-adc: Enable all stmpe-adc interrupts just oncePhilippe Schenker1-3/+3
This commit will enable the interrupts of all channels handled by this driver only once in the probe function. This will improve performance because one byte less has to be written over i2c on each read out of the adc. On the fastest ADC mode this will improve read out speed by 15%.

2019-05-11iio: stmpe-adc: Reinit completion struct on begin conversionPhilippe Schenker1-0/+4
In some cases, the wait_completion got interrupted. This caused the error-handling to mutex_unlock the function. The before turned on interrupt then got called anyway. In the ISR then completion() was called causing wrong adc-values returned in a following adc-readout. Reinitialise completion struct to make sure the counter is zero when beginning a new adc-conversion.

2019-05-07Merge tag 'staging-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/stagingLinus Torvalds99-2265/+5285
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 git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linuxLinus Torvalds1-1/+0
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

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.
