2023-03-11iio: Rename iio_trigger_poll_chained and add kernel-docMehdi Djait1-1/+1
Rename the function to iio_trigger_poll_nested. Add kernel-doc with a note on the context where the function is expected to be called.

2022-02-18iio:pressure:zpa2326: Move exports into IIO_ZPA2326 namespaceJonathan Cameron1-6/+6
In order to avoid unnecessary pollution of the global symbol namespace move the common/library functions into a specific namespace and import that into the bus specific device drivers that use them.

2021-05-17iio: core: move @id from struct iio_dev to struct iio_dev_opaqueJonathan Cameron1-1/+2
Continuing from Alexandru Ardelean's introduction of the split between driver modifiable fields and those that should only be set by the core. This could have been done in two steps to make the actual move after introducing iio_device_id() but there seemed limited point to that given how mechanical the majority of the patch is. Includes fixup from Alex for missing mxs-lradc-adc conversion.

2020-06-20iio: Move attach/detach of the poll func to the coreLars-Peter Clausen1-17/+10
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.

2020-06-14iio: remove explicit IIO device parent assignmentAlexandru Ardelean1-1/+0
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.

2019-10-22iio: pressure: zpa2326: fix iio_triggered_buffer_postenable positionAlexandru Ardelean1-7/+9
The iio_triggered_buffer_{predisable,postenable} functions attach/detach the poll functions. The iio_triggered_buffer_postenable() should be called before (to attach the poll func) and then the The iio_triggered_buffer_predisable() function is hooked directly without anything, which is probably fine, as the postenable() version seems to also do some reset/wake-up of the device. This will mean it will be easier when removing it; i.e. it just gets removed.

2017-09-25iio: pressure: zpa2326: Remove always-true check which confuses gccGeert Uytterhoeven1-7/+3
With gcc 4.1.2: drivers/iio/pressure/zpa2326.c: In function ‘zpa2326_wait_oneshot_completion’: drivers/iio/pressure/zpa2326.c:868: warning: ‘ret’ may be used uninitialized in this function When testing for "timeout < 0", timeout is already guaranteed to be strict negative, so the branch is always taken, and ret is thus always initialized. But (some version of) gcc is not smart enough to notice. Remove the check to fix this. As there is no other code in between assigning the error codes and returning them, the error codes can be returned immediately, and the intermediate variable can be dropped. Drop the "else" to please checkpatch.
