* iio:cdc:ad7150: Move driver out of staging.Jonathan Cameron2021-04-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | This capacitance to digital converter (CDC) driver is compliant with the IIO ABI. Note, not all features supported (e.g. window event modes) but the driver should be in a useful functional state. The cleanup was done against QEMU emulation of the device rather than actual hardware. Whilst this was a bit of an experiment, it made it easy to confirm that the driver remained in a consistent working state through the various refactors. If it worked in the first place, it should still be working after this cleanup. Given some IIO drivers require expensive hardware setups, (not particularly true with this one) the use of QEMU may provide a viable way forward for providing testing during code changes where previously we'd had to rely on sharp eyes and crossed fingers. Note, no explicit MAINTAINERS entry as it will be covered by the generic catch-alls for ADI and IIO drivers which are sufficient.

* iio: Add basic unit test for iio_format_value()Lars-Peter Clausen2021-03-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IIO core provides a function to do formatting of fixedpoint numbers. In the past there have been some issues with the implementation of the function where for example negative numbers were not handled correctly. Introduce a basic unit test based on kunit that tests the function and ensures that the generated output matches the expected output. This gives us some confidence that future modifications to the function implementation will not break ABI compatibility. To run the unit tests follow the kunit documentation and add CONFIG_IIO=y CONFIG_IIO_TEST_FORMAT=y to the .kunitconfig and run > ./tools/testing/kunit/kunit.py run Configuring KUnit Kernel ...

* iio: Kconfig: Provide title for IIO_TRIGGERED_EVENT symbolAlexandru Ardelean2020-09-291-1/+1
| | | | | | | | | | | | | | | | | | | For some embedded systems, a workflow involving external kernel modules that implement IIO devices is more practical than working with in-tree sources. Kconfig symbols without any titles do not show up in menuconfig, and as such are more difficult to configure granularly, as they need to be selected by potentially unused/un-needed drivers. Albeit, the IIO_TRIGGERED_EVENT is used by a single mainline driver, this could allow for some out-of-tree drivers to use this kmod. This change adds a title to the IIO_TRIGGERED_EVENT Kconfig symbol.

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.

* iio: afe: rescale: new driverPeter Rosin2018-04-281-0/+1
| | | | | | | | | | | | | | | If an ADC channel measures the midpoint of a voltage divider, the interesting voltage is often the voltage over the full resistance. E.g. if the full voltage is too big for the ADC to handle. Likewise, if an ADC channel measures the voltage across a shunt resistor, with or without amplification, the interesting value is often the current through the resistor. This driver solves these problems by allowing to linearly scale a channel and/or by allowing changes to the type of the channel.

| | | | | | | | | | | | | | | | | | | | | The ACCES 104-QUAD-8 is a general purpose quadrature encoder counter/interface board. The 104-QUAD-8 is capable of monitoring the outputs of eight encoders via four on-board LSI/CSI LS7266R1 24-bit dual-axis quadrature counter chips. Core functions handled by the LS7266R1, such as direction and total count, are available. Performing a write to a counter's IIO_CHAN_INFO_RAW sets the counter and also clears the counter's respective error flag. Although the counters have a 25-bit range, only the lower 24 bits may be set, either directly or via a counter's preset attribute. Interrupts are not supported by this driver. This driver adds IIO support for the ACCES 104-QUAD-8 and ACCES 104-QUAD-4. The base port addresses for the devices may be configured via the base array module parameter.

* Revert "iio: add configuration option for debug support"Greg Kroah-Hartman2013-08-051-7/+0
| | | | | | | | | | | | | This reverts commit 98a5e9e99d05e9b6a14778b85631b55e8e349990. IIO, like the rest of the kernel, should rely on dynamic debugging, not have a special config option for it. That way, no user has to rebuild their kernel to have debug messages, which is a good thing, let's not revert back to the bad old days of the 2000's.
