On one board I found that: probe of 5-0028 returned 1 after 259547 usecs While some of this time is attributable to the pile of i2c transfers that we do at probe time, the lion's share (over 200 ms) is sitting waiting in the polling loop in sx9310_init_compensation() waiting for the hardware to indicate that it's done. There's no reason to block probe of all other devices on our probe. Turn on async probe.

2020-08-22iio:proximity:mb1232: Fix timestamp alignment and prevent data leak.Jonathan Cameron
One of a class of bugs pointed out by Lars in a recent review. iio_push_to_buffers_with_timestamp assumes the buffer used is aligned to the size of the timestamp (8 bytes). This is not guaranteed in this driver which uses a 16 byte s16 array on the stack As Lars also noted this anti pattern can involve a leak of data to userspace and that indeed can happen here. We close both issues by moving to a suitable structure in the iio_priv() data with alignment ensured by use of an explicit c structure. This data is allocated with kzalloc so no data can leak appart from previous readings. In this case the forced alignment of the ts is necessary to ensure correct padding on x86_32 where the s64 would only be 4 byte aligned.

2020-06-20iio: Move attach/detach of the poll func to the coreLars-Peter Clausen
All devices using a triggered buffer need to attach and detach the trigger to the device in order to properly work. Instead of doing this in each and every driver by hand move this into the core. At this point in time, all drivers should have been resolved to attach/detach the poll-function in the same order. This patch removes all explicit calls of iio_triggered_buffer_postenable() & iio_triggered_buffer_predisable() in all drivers, since the core handles now the pollfunc attach/detach. The more peculiar change is for the 'at91-sama5d2_adc' driver, since it's not immediately obvious that removing the hooks doesn't break anything. Eugen was able to test on at91-sama5d2-adc driver, sama5d2-xplained board. All seems to be fine.

There is a mix of trigger assignments with some iio device parent assignments that are removed via this patch. JC: A few more added via inspection of all parent = statements in drivers/iio. Some of these may just have crossed with this series, others were less obvious to scripting due to some cross file / module boundary calls.

2020-06-14iio: remove explicit IIO device parent assignmentAlexandru Ardelean
This patch applies the semantic patch: @@ expression I, P, SP; @@ I = devm_iio_device_alloc(P, SP); ... - I->dev.parent = P; It updates 302 files and does 307 deletions. This semantic patch also removes some comments like '/* Establish that the iio_dev is a child of the i2c device */' But this is is only done in case where the block is left empty. The patch does not seem to cover all cases. It looks like in some cases a different variable is used in some cases to assign the parent, but it points to the same reference. In other cases, the block covered by ... may be just too big to be covered by the semantic patch. However, this looks pretty good as well, as it does cover a big bulk of the drivers that should remove the parent assignment.

2020-05-21iio: proximity: ping: pass reference to IIO device as param to ping_read()Alexandru Ardelean
Since there will be some changes to how iio_priv_to_dev() is implemented, it could be that the helper becomes a bit slower, as it will be hidden away in the IIO core. But even without that rework, this looks like it can pass the 'indio_dev' object to ping_read() and obtain the state struct via iio_priv() which is a preferred practice than going back-n-forth (getting the state-struct, then using iio_priv_to_dev() to get the indio_dev object back).

2020-02-14iio: srf04: add power management featureAndreas Klinger
Add suspend and resume operations for being used by optional power management. The suspend function is switching off an GPIO which can be used by the hardware to switch power off. The resume function is switching the GPIO on and sleeps an adjustable time to give the device a chance to be up and running. If activated the driver gets into autosuspend after some time of inactivity.

2019-12-01iio: ping: add parallax ping sensorsAndreas Klinger
Add support for parallax ping and laser ping sensors with just one pin for trigger and echo signal. This driver is based on srf04. In contrast to it it's necessary to change direction of the pin and to request the irq just for the period when the echo is rising and falling. Because this adds a lot of cases there is this individual driver for handling this type of sensors. Add a new configuration variable CONFIG_PING to Kconfig and Makefile.

positions The iio_triggered_buffer_predisable() should be called last, to detach the poll func after the devices has been suspended. This change re-organizes things a bit so that the postenable & predisable are symmetrical. It also converts the preenable() to a postenable(). Not stable material as there is no known problem with the current code, it's just not consistent with the form we would like all the IIO drivers to adopt so as to allow subsystem wide changes.

2019-04-04iio: proximity: as3935: fix use-after-free on device removeSven Van Asbroeck
This driver's probe() uses a mix of devm_ and non-devm_ functions. This means that the remove order will not be the exact opposite of the probe order. Remove order: 1. remove() executes: iio_device_unregister iio_triggered_buffer_cleanup iio_trigger_unregister (A) 2. core frees devm resources in reverse order: free_irq iio_trigger_free iio_device_free In (A) the trigger has been unregistered, but the irq handler is still registered and active, so the trigger may still be touched via interrupt -> as3935_event_work. This is a potential use-after-unregister. Given that the delayed work is never canceled explicitly, it may run even after iio_device_free. This is a potential use-after-free. Solution: convert all probe functions to their devm_ equivalents. Add a devm callback, called by the core on remove right after irq_free, which explicitly cancels the delayed work. This will guarantee that all resources are freed in the correct order. As an added bonus, some boilerplate code can be removed.

This driver was originally written by ST in 2016 as a misc input device driver, and hasn't been maintained for a long time. I grabbed some code from it's API and reformed it into an iio proximity device driver. This version of driver uses i2c bus to talk to the sensor and polling for measuring completes, so no irq line is needed.
