* iio: adc: ad7192: handle regulator voltage error firstAlexandru Ardelean2021-05-131-7/+4
| | | | | | | | | | | | | | | | | | | | | | This change fixes a corner-case, where for a zero regulator value, the driver would exit early, initializing the driver only partially. The driver would be in an unknown state. This change reworks the code to check regulator_voltage() return value for negative (error) first, and return early. This is the more common idiom. Also, this change is removing the 'voltage_uv' variable and using the 'ret' value directly. The only place where 'voltage_uv' is being used is to compute the internal reference voltage, and the type of this variable is 'int' (same are for 'ret'). Using only 'ret' avoids having to assign it on the error path.

* iio: adc: ad7192: Avoid disabling a clock that was never enabled.Jonathan Cameron2021-05-131-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | Found by inspection. If the internal clock source is being used, the driver doesn't call clk_prepare_enable() and as such we should not call clk_disable_unprepare() Use the same condition to protect the disable path as is used on the enable one. Note this will all get simplified when the driver moves over to a full devm_ flow, but that would make backporting the fix harder. Fix obviously predates move out of staging, but backporting will become more complex (and is unlikely to happen), hence that patch is given in the fixes tag. Alexandru's sign off is here because he added this patch into a larger series that Jonathan then applied.

* iio: adc: ad7124: Fix potential overflow due to non sequential channel numbersJonathan Cameron2021-05-131-0/+7
| | | | | | | | | | | | | | | | | | | | | Channel numbering must start at 0 and then not have any holes, or it is possible to overflow the available storage. Note this bug was introduced as part of a fix to ensure we didn't rely on the ordering of child nodes. So we need to support arbitrary ordering but they all need to be there somewhere. Note I hit this when using qemu to test the rest of this series. Arguably this isn't the best fix, but it is probably the most minimal option for backporting etc. Alexandru's sign-off is here because he carried this patch in a larger set that Jonathan then applied.

* | iio: adc: Kconfig: make AD9467 depend on ADI_AXI_ADC symbolAlexandru Ardelean2021-04-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Because a dependency on HAS_IOMEM and OF was added for the ADI AXI ADC driver, this makes the AD9467 driver have some build/dependency issues when OF is disabled (typically on ACPI archs like x86). This is because the selection of the AD9467 enforces the ADI_AXI_ADC symbol which is blocked by the OF (and potentially HAS_IOMEM) being disabled. To fix this, we make the AD9467 driver depend on the ADI_AXI_ADC symbol. The AD9467 driver cannot operate on it's own. It requires the ADI AXI ADC driver to stream data (or some similar IIO interface). So, the fix here is to make the AD9467 symbol depend on the ADI_AXI_ADC symbol. At some point this could become it's own subgroup of high-speed ADCs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These devices are not able to mask the signal used as a data ready interrupt. As such they previously requested the irq then immediately disabled it. Now we can avoid the potential of a spurious interrupt by avoiding the irq being auto enabled in the first place. I'm not sure how this code could have been called with the irq already disabled, so I believe the conditional would always have been true and have removed it.

This includes providing a new directory per buffer that combines what was previously in buffer/ and scan_elements/. Old interfaces still in place for compatiblity. Note immuatable branch for scmi patches to allow for some significant rework going on in that subsystem. Merge required updating to reflect some changes in IIO. Late rebase to fix some wrong fixes tags due to some earlier rebases made necessary by messing up the immutable branch. IIO New Device Support * adi,ad5686 - Add info to support AD5673R and AD5677R * bosch,bmi088 - New driver supporting this accelerometer + gyroscope * cros_ec_mkbp - New driver for this proximity sensor that exposes a 'front' sensor. Very simple switch like device, but driver allows it to share interface with more sophisticated proximity sensors. * iio_scmi - New driver to support ARM SCMI protocol to expose underlying accelerometers and gyroscopes via this firmware interface. * st,st_magn - Add ID for IISMDC magnetometer. * ti,ads131e0 - New driver supporting ads131e04, ads131e06 and ads131e08 24 bit ADCs Counter New Device Support * IRQ or GPIO based counter - New driver for a conceptually simple counter that uses interrupts to perform the count. Features * core - Dual buffer supprt including: Various helpers to centralize handling of bufferer related elements. Document existing and new IOCTLs Register the IIO chrdev only if it can actually be used for anything. Rework attribute group creation in the core (lots of patches) Merge buffer/ and scan_elements/ entries into one list + maintain backwards compatible set. Introduce the internal logic and IOCTL to allow multiple buffers + access to an anon FD per buffer to actually read from it. Tidy up tools/iio/iio_generic_buffer and switch to new interfaces. Update ABI docs. A few follow up fixes, unsuprising as this was a huge bit of rework. - Move common case setting of trig->parent to the core. - Provide an iio_read_channel_processed_scale() to avoid loss of precision from iio_read_channel_processed() then applying integer scale. Use it in ntc_thermistor driver in hwmon. - Allow drivers to specify labels from elsewhere than DT. Use it for bmc150 and kxcjk-1013 labels related to position on 2 in one tablets. - Document label usage for proximity and accelerometer sensors. - Some local variable renames for consistency tools - Add -a parameter to iio_event_monitor to allow autoenabling of events. * acpi_als - Add trigger support for devices that don't support notification method. * adi,ad7124 - Allow more than 8 channels. This is a complex little device, but is capable of supporting up to 16 channels if the share certain configuration settings. * hrtimer-trigger - Support sampling frequency below 1Hz. * mediatek,mt8195-auxadc - Add compatible to binding docs (always also includes mt8173) * st,stm32-adc - Enable timetamps when not using DMA. * vishay,vcnl3020 - Sampling frequency control. Cleanup and minor fixes: * treewide - Use some getter and setter functions instead of opencoding. - Set of fixes for pointless casts in various drivers. - Avoid wrong kernel-doc marking on comment blocks. - Fix various other minor kernel-doc issues shown by W=1 * core - Use a signed temporary for IIO_VAL_FRACTIONAL_LOG2 to avoid odd casts. - Fix IIO_VAL_FRACTIONAL_LOG2 for values between -1.0 and 0.0 - Add unit tests for iio_format_value() * docs - Fix formatting/typos in iio_configfs.rst and buffers.rst - Add documentation of index in buffers.rst - Fix scan element description - Avoid some issues with HTML generation from ABI docs by moving duplicated defintions to more generic files. - Drop reference to long dead mailing list. * 104-quad - Remove left over deprecated IIO counter ABI. * adi,adi-axi-adc - Fix wrong bit of docs. * adi,ad5791 - Typos * adi,ad9834 - Switch to device managed functions in probe. * adi,adis* - Add and use helpers for locking to reduced duplication. * adi,adis16480 - Fix calculation of sampling frequency when using pulse per second input. * adi,adis16475 - Calculate the IMU scaled internal sampling rate and runtime depending on sysfs based configuration rather than getting from DT.

This is not possible to do when using more than 8 channels as AD7124-8 has only 8 configuration registers. To allow the user to use all channels at once the driver will keep in memory configurations for all channels but will program only 8 of them at a time on the device. If multiple channels have the same configuration, only one configuration register will be used. If there are more configurations than available registers only the last 8 used configurations will be allowed to exist on the device in a LRU fashion.

Also, the INDIO_BUFFER_SOFTWARE has been removed from the assignments of 'indio_dev->modes' because it is set by devm_iio_kfifo_buffer_setup().

For this to work, the driver needs to register an IIO_TIMESTAMP channel. Do this. For DMA, it's not as easy, because we don't push the buffers out of stm32_adc_trigger, but out of stm32_adc_dma_buffer_done, which runs in a tasklet scheduled after a DMA completion. Preferably, the DMA controller would copy us the timestamp into that buffer as well. Until this is implemented, restrict timestamping support to only PIO. For low-frequency sampling, PIO is probably good enough.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for Thermal Monitoring part of PMIC5. This part is closely coupled with ADC, using it's channels directly. ADC-TM support generating interrupts on ADC value crossing low or high voltage bounds, which is used to support thermal trip points.
