iio: light: Add gain-time-scale helpers Some light sensors can adjust both the HW-gain and integration time. There are cases where adjusting the integration time has similar impact to the scale of the reported values as gain setting has. IIO users do typically expect to handle scale by a single writable 'scale' entry. Driver should then adjust the gain/time accordingly. It however is difficult for a driver to know whether it should change gain or integration time to meet the requested scale. Usually it is preferred to have longer integration time which usually improves accuracy, but there may be use-cases where long measurement times can be an issue. Thus it can be preferable to allow also changing the integration time - but mitigate the scale impact by also changing the gain underneath. Eg, if integration time change doubles the measured values, the driver can reduce the HW-gain to half. The theory of the computations of gain-time-scale is simple. However, some people (undersigned) got that implemented wrong for more than once. Add some gain-time-scale helpers in order to not dublicate errors in all drivers needing these computations.

iio: Kconfig: Provide title for IIO_TRIGGERED_EVENT symbol 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.

iio:cdc:ad7150: Move driver out of staging. 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:trigger:sysfs Move out of staging. This simple driver is rather useful. No issues about its interface have been raised for some time hence the proposal to move it out of staging. Signed-off-by: Jonathan Cameron <jic23@kernel.org>

iio: position: Add support for Azoteq IQS624/625 angle sensors This patch adds support for the Azoteq IQS624 and IQS625 angular position sensors, capable of reporting the angle of a rotating shaft down to 1 and 10 degrees of accuracy, respectively. This patch also introduces a home for linear and angular position sensors. Unlike resolvers, they are typically contactless and use the Hall effect.
