2021-08-15iio: ltc2983: fix device probeNuno Sá1-16/+14
There is no reason to assume that the IRQ rising edge (indicating that the device start up phase is done) will happen after we request the IRQ. If the device is already up by the time we request it, the call to 'wait_for_completion_timeout()' will timeout and we will fail the device probe even though there's nothing wrong. Fix it by just polling the status register until we get the indication that the device is up and running. As a side effect of this fix, requesting the IRQ is also moved to after the setup function.

2021-07-19iio: temperature: tmp006: make sure the chip is powered up in probeAlexandru Ardelean1-11/+22
When the device is probed, there's no guarantee that the device is not in power-down mode. This can happen if the driver is unregistered and re-probed. To make sure this doesn't happen, the value of the TMP006_CONFIG register (which is read in the probe function and stored in the device's private data) is being checked to see if the MOD bits have the correct value. This is a fix for a somewhat-rare corner case. As it stands, this doesn't look like a high priority to go into the Fixes route.

This change converts the driver to register via devm_iio_device_register(). For the tmp006_powerdown() hook, this uses a devm_add_action() hook to put the device in powerdown mode when it's unregistered. With these changes, the remove hook can be removed. The i2c_set_clientdata() call is staying around as the private data is used in the PM routines.

2021-05-10iio: hid-sensors: select IIO_TRIGGERED_BUFFER under HID_SENSOR_IIO_TRIGGERAlexandru Ardelean1-1/+0
During commit 067fda1c065ff ("iio: hid-sensors: move triggered buffer setup into hid_sensor_setup_trigger"), the iio_triggered_buffer_{setup,cleanup}() functions got moved under the hid-sensor-trigger module. The above change works fine, if any of the sensors get built. However, when only the common hid-sensor-trigger module gets built (and none of the drivers), then the IIO_TRIGGERED_BUFFER symbol isn't selected/enforced. Previously, each driver would enforce/select the IIO_TRIGGERED_BUFFER symbol. With this change the HID_SENSOR_IIO_TRIGGER (for the hid-sensor-trigger module) will enforce that IIO_TRIGGERED_BUFFER gets selected. All HID sensor drivers select the HID_SENSOR_IIO_TRIGGER symbol. So, this change removes the IIO_TRIGGERED_BUFFER enforcement from each driver.

Jonathan writes: 1st set of IIO/counter device support, features and cleanup in the 5.13 cycle Big set in here from Alexandru Ardelean enabling multiple buffer support. 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.

2021-03-25iio: temperature: tmp007: use device-managed functions in probeAlexandru Ardelean1-21/+15
This change converts the driver to use device-managed functions in the probe function. The power-down call is handled now via a devm_add_action_or_reset() hook, and then devm_iio_device_register() can be used to register the IIO device. The final aim here would be for IIO to export only the device-managed functions of it's API. That's a long way to go and this a small step in that direction.

For some time the market wants medical grade accuracy in medical range, while still retaining the declared accuracy outside of the medical range within the same sensor. That is why we created extended calibration which is automatically switched to when object temperature is too high. This patch also introduces the object_ambient_temperature variable which is needed for more accurate calculation of the object infra-red footprint as sensor's ambient temperature might be totally different than what the ambient temperature is at object and that is why we can have some more errors which can be eliminated. Currently this temperature is fixed at 25, but the interface to adjust it by user (with external sensor or just IR measurement of the other object which acts as ambient), will be introduced in another commit.

2020-06-14iio: Remove superfluous of_node assignmentsLars-Peter Clausen1-1/+0
If a driver does not assign an of_node to a IIO device to IIO core will automatically assign the of_node of the parent device. This automatic assignment is done in the iio_device_register() function. There is a fair amount of drivers that currently manually assign the of_node of the IIO device. All but 4 of them can make use of the automatic assignment though. The exceptions are: * mxs-lradc-adc: Which uses the of_node of the parent of the parent. * stm32-dfsdm-adc, stm32-adc and stm32-dac: Which reference the of_node assigned to the IIO device before iio_device_register() is called. All other drivers are updated to use automatic assignment. This reduces the amount of boilerplate code involved in setting up the IIO device. The patch has mostly been auto-generated with the following semantic patch // <smpl> @exists@ expression indio_dev; expression parent; @@ indio_dev = \(devm_iio_device_alloc\|iio_device_alloc\)(&parent, ...) ... -indio_dev->dev.of_node = parent.of_node; @exists@ expression indio_dev; expression parent; @@ indio_dev = \(devm_iio_device_alloc\|iio_device_alloc\)(parent, ...) ... -indio_dev->dev.of_node = parent->of_node; // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>

This semantic patch also removes some comments like '/* Establish that the iio_dev is a child of the i2c device */' But this is is only done in case where the block is left empty. The patch does not seem to cover all cases. It looks like in some cases a different variable is used in some cases to assign the parent, but it points to the same reference. In other cases, the block covered by ... may be just too big to be covered by the semantic patch. However, this looks pretty good as well, as it does cover a big bulk of the drivers that should remove the parent assignment.

2020-05-10iio: hid-sensors: move triggered buffer setup into hid_sensor_setup_triggerAlexandru Ardelean1-9/+3
The main intent here is to get rid of the iio_buffer_set_attrs() helper, or at least rework it's usage a bit. The problem with that helper is that it needs a pointer to the buffer, which makes supporting multiple buffers per IIO device a bit more cumbersome. The hid_sensor_setup_trigger() is pretty much used in the same way: - iio_triggered_buffer_setup() gets called before - then hid_sensor_setup_trigger() and hid_sensor_setup_batch_mode() gets called which may attach some fifo attributes This change merges the 2 together under the hid_sensor_setup_trigger() function. Only the &iio_pollfunc_store_time is passed to all devices, so it's not even required to pass it explicitly outside of the common hid_sensor_setup_trigger() function. Moving the devm_iio_triggered_buffer_setup/cleanup() calls into the common place code can help the rework of the buffer code, since it is in one place. One detail of the change is that there are 2 drivers that use devm_iio_triggered_buffer_setup(). That function gets implicitly replaced with iio_triggered_buffer_setup()/cleanup(), but since all drivers call both hid_sensor_setup_trigger9) & hid_sensor_remove_trigger() trigger, the iio_triggered_buffer_cleanup() piggy backs on the hid_sensor_remove_trigger() call, which should cover the cleanup.

2019-11-23iio: maxim_thermocouple: add thermocouple_type sysfs attributeAndrea Merello1-3/+41
We added a sysfs ABI for getting/setting the type of a thermocouple. This driver supports chips that support specific fixed thermocouple types; we cannot set it, but still we can add this sysfs attribute in RO mode to read-back the thermocouple type. This driver supports actually several chips: - max6675 - max31855[k/j/n/s/t/e/r]asa family Max6675 supports only K-type thermocouples, so we can just report that. Each chip in max31855 family supports just one specific thermocouple type (in the obvious way: i.e. max31855jasa supports J-type). This driver did accept a generic SPI ID and OF compatible "max31855" which does not give any clue about which chip is really involved (and unfortunately it seems we have no way to detect it). This patch introduces a new set of, more specific, SPI IDs and OF compatible strings to better match the chip type. The old, generic, "max31855" binding is kept for compatibility reasons, but this patch aims to deprecate it, so, should we hit it, a warning is spit. In such case the reported thermocouple type in sysfs is '?', because we have no way to know. Regarding the implementation: the thermocouple type information is stored in the driver private data and I've kept only two maxim_thermocouple_chip types in order to avoid a lot of duplications (seven chip types with just a different thermocouple type). RFT because I have no real HW to test this.

2019-11-23iio: max31856: add support for runtime-configuring the thermocouple typeAndrea Merello1-1/+40
The sensor support various thermocouple types (e.g. J, K, N, ...). The driver allows to configure this parameter using a DT property. This is useful when i.e. the thermocouple is physically tied to the sensor and it is usually not removed, or when it is at least known in advance which sensor will be connected to the circuit. However, if the user can randomly connect any kind of thermocouples (i.e. the device exposes a connector, and the user is free to connect its own sensors), it would be more appropriate to provide a mechanism to dynamically switch from one thermocouple type to another. This can be i.e. handled in userspace by a GUI, a configuration file or a program that detects the thermocouple type by reading a GPIO, or a eeprom on the probe, or whatever. This patch adds a IIO attribute that can be used to override, at run-time, the DT-provided setting (which serves as default).

This sensor can perform samples averaging in hardware, but currently the driver leaves this setting alone (default is no averaging). This patch binds this HW setting to the "oversampling_ratio" IIO attribute and allows the user to set the averaging as desired (the HW supports averaging of 2, 5, 8 or 16 samples; in-between values are rounded up).

2019-11-23iio: max31856: add option for setting mains filter rejection frequencyAndrea Merello1-0/+50
This sensor has an embedded notch filter for reducing interferences caused by the power mains. This filter can be tuned to reject either 50Hz or 60Hz (and harmonics). Currently the said setting is left alone (the sensor defaults to 60Hz). This patch introduces a IIO attribute that allows the user to set the said filter to the desired frequency. NOTE: this has been intentionally not tied to any DT property to allow the configuration of this setting from userspace, e.g. with a GUI or by reading a configuration file, or maybe reading a GPIO tied to a physical switch or accessing some device that can autodetect the line frequency.

Register EE_VERSION contains mixture of calibration information and DSP version. So far, because calibrations were definite, the driver compatibility depended on whole contents, but in the newer production process the calibration part changes. Because of that, value in EE_VERSION will be changed and to avoid that calibration value is same as DSP version the MSB in calibration part was fixed to 1. That means existing calibrations (medical and consumer) will now have hex values (bits 8 to 15) of 83 and 84 respectively. Driver compatibility should be based only on DSP version part of the EE_VERSION (bits 0 to 7) register.
