2021-05-17iio: gyro: fxa21002c: Balance runtime pm + use pm_runtime_resume_and_get().Jonathan Cameron1-10/+1
In both the probe() error path and remove() pm_runtime_put_noidle() is called which will decrement the runtime pm reference count. However, there is no matching function to have raised the reference count. Not this isn't a fix as the runtime pm core will stop the reference count going negative anyway. An alternative would have been to raise the count in these paths, but it is not clear why that would be necessary. Whilst we are here replace some boilerplate with pm_runtime_resume_and_get() Found using coccicheck script under review at: https://lore.kernel.org/lkml/20210427141946.2478411-1-Julia.Lawall@inria.fr/ Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Reviewed-by: Rui Miguel Silva <rui.silva@linaro.org> Reviewed-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Link: https://lore.kernel.org/r/20210509113354.660190-2-jic23@kernel.org
2021-05-17iio: accel: kxcjk-1013: Add support for KX023-1025Stephan Gerhold1-0/+93
The KX023-1025 accelerometer [1] seems to be some mixture of KXCJK and KXTF9. It has the motion interrupt functionality from KXCJK but also the tap detection from KXTF9, and a lot more functionality. The configuration register map seems fairly different at first, but actually all register bits used by the kxcjk-1013 driver are available at the same bit positions on KX023-1025. It's just quite misleading because: 1. The registers have entirely different names and are at different addresses, but the bits are mostly named the same (and mean the same). 2. There are many more registers and bits used that are reserved on KXCJK to enable additional functionality. Ignoring all additionally available functionality for now, the KX023 works just fine after setting up the struct with the correct register addresses. The only difference that needs to be handled additionally is that the KX023 supports two configurable interrupt lines (INT1/2). For now only INT1 is supported so we route all interrupts used by the driver there.

2021-05-17iio: accel: kxcjk-1013: Refactor configuration registers into structStephan Gerhold1-42/+82
Most Kionix accelerometers seem to use fairly consistent register bits, but the register addresses are not necessarily the same. This is already partially the case for the KXTF9 (added in commit 1540d0106bcb ("iio: accel: kxcjk1013: add support for KXTF9")), which has some registers at different addresses. However, it's even much worse for the KX023-1025. All register bits used by the kxcjk-1013 driver seem to be fully compatible with KX023, but it has most registers at totally different addresses. In preparation to add support for KX023-1025, move the fixed register addresses into a struct so we can change them for KX023 more easily.

We can utilize separate drivers for accelerometer and magnetometer, so here is the glue driver to enable LSM9DS0 IMU support. The idea was suggested by Crestez Dan Leonard in [1]. The proposed change was sent as RFC due to race condition concerns, which are indeed possible.

2021-05-17iio: adc: add ADC driver for the TI TSC2046 controllerOleksij Rempel4-0/+735
Basically the TI TSC2046 touchscreen controller is 8 channel ADC optimized for the touchscreen use case. By implementing it as an IIO ADC device, we can make use of resistive-adc-touch and iio-hwmon drivers. Polled readings are currently not implemented to keep this patch small, so iio-hwmon will not work out of the box for now. So far, this driver was tested with a custom version of resistive-adc-touch driver, since it needs to be extended to make use of Z1 and Z2 channels. The X/Y are working without additional changes.

channel properties Settling time and over sampling is a typical challenge for different IIO ADC devices. So, introduce channel specific settling-time-us and oversampling-ratio properties to cover this use case.

2021-05-17iio: Documentation: move incompatible ABI to obsoleteMauro Carvalho Chehab2-82/+182
Commit 63cd35f34d2e ("iio: Documentation: update definitions for bufferY and scan_elements") updated iio documentation in order to point to the newly per-buffer API, as it is now possible to support multi buffers. While the previous ABI will be kept forever, the best is for applications to use the 5.11+ ABI. So, move the legacy one ABI/obsolete. This fixes an issue with scripts/get_abi.pl, that doesn't accept two different Kernel version support for the same API set.

Sensor has support for both i2c and serial communication interfaces. Both offer very similar set of features. Minor differences don't impact overall functionality like doing measurements, etc. Support for i2c have already been added, this patch adds support for the latter ie. serial interface.
