The AD7150 family of devices power up in continues conversion mode. We can stay in this mode, unless power consumption becomes a real issue. Actually the event generation as well as the running average relies on continues conversion mode, so we better stay there. Signed-off-by:

Minimal changes to code layout as going to do chan spec conversion shortly. Otherwise, there are numerous code sharing opportunities in here and abi elements that are uterly non compliant. Signed-off-by:

Straight forward change in the core, but required some drivers to not use the IIO_CHAN macro as that doesn't allow setting this bit (and is going away anyway). Hence the churn. Tested on max1363 with a couple of supported parts. V2: differential bit in code got 7 bits and direction 1. Reversed that. Issue spotted by Michael - thanks! Signed-off-by:

Should always have been IIO_EV_DIR_MAX as that's what it actually controls. Also reduced the number to 4 as not yet seen a case needing more and this is not userspace visible anyway. Signed-off-by:

Makes unusual event related attributes look a lot more like the core ones. V2: Make sure the utils that set these up can handle the codes. V3: rebase Reported-by:

This set also includes quite a number of bug fixes of particularly remove functions. Necessary due to issue pointed out in Bart Van Assche's patch: docs/driver-model: Document device.groups V2: Rebase due to patch reordering. V3: Pull various error fixes and cleanups out into their own patches. Signed-off-by:

This costs us nothing in event storage (as we are carrying a 64 bit timestamp in the structure) and gives us lots more room to play with. Also allows for more channels which some parts need. V2: Cleanup some loose ends (such as the switch with only one option now). Signed-off-by:

This is as light as possible on changes to current drivers. Some drivers make assumptions that their masks fit in a single long. Given they were previously working this is clearly valid if not tidy. The max1363 is an example where there should be no such assumptions. V2: Add the new ad5933 Signed-off-by:

The scan mask will be dynamically assigned in register, so don't use it before that. In adis16260 I've moved it as I know this driver has userspace code. Same for sca3000 where it is cost free due to hardware buffer. Can do that for the others, but in theory userspace code should always have been checking these and setting them appropriately anyway! V2: Clear default mask out of adis16400 as reported by Michael Signed-off-by:

Also includes the inX -> in_voltageX and outX -> out_voltageX conversions. To keep lines short quite a lot of supressing of directories was needed. Signed-off-by:

Jonathan Cameron authored
Also involves changing current inX outX to in_voltageX and out_voltageX V2: squash users of the IIO_CHAN_OUT macro and get rid of it. There are very few of these, so it is easier to fix them. Signed-off-by:

No way iio_device_allocate or iio_device_unregister effected by regulators so copying tricks not needed. This is really about regularizing the layout of drivers. Signed-off-by:

This includes calling iio_free_device as that should only be called before the device has been registered. Also one case of iio_free_device being called on a registered device. This has been pulled out of the reworking attributes patch. Signed-off-by:

These are no longer needed. Requires a few driver updates for places "sysfs.h" should have been present but wasn't. Signed-off-by:

Now the old method is long gone, lets get rid of the _ex and whilst here remove the unused id parameter. Trivial mechanical change, but will break any out of tree drivers using this. V2: rebase V3: rebase Signed-off-by:

Use new simple ida allocation functions to remove some boilerplate code. Also, now we only have one chdev per device we don't need to maintain a separate ida for minor numbers. Just use the devices id. Signed-off-by:

We don't have a use case for these. Two drivers appeared to use them but both report all events on the first. V2: Remove now irrelevant comment. V3: Include fixup for adc/ad7280a.c Signed-off-by:

Now we have combined all chrdevs into one, some bits and bobs are only needed in industrialio-core.c and don't need to be in the core header. Also remove some unused defines. Signed-off-by:

Sorry all, this one is very invasive, though the driver changes are just trivial interface fixes. Not all done yet. V2 - bring the sca3000 with us. V3 - fix ade7758 bugs in conversion. V4 - add ad5933 Signed-off-by:

This no longer has any purpose given all chrdevs are pretty much the same now the event interfaces are done via anon fds Signed-off-by:

Change suggested by Arnd Bergmann. No real reason to have two chrdevs per device. This step merges them into one. Currently this means that events will only work on devices with buffers. THat will be remedied shortly. V2: set name for event attribute groups. Otherwise they all sorts of fun occurs on dynamic channel event attribute creation. Signed-off-by:
