Factor out all the differences between MLX90614 and other similar chips into a structure which describes the chip and allows abstracting out the differences from the driver code. No functional change. This patch moves all the RAM and EEPROM IO opcodes into the descriptor structure and combines them, instead of combining the opcode and offset in macros. Acked-by:

Document support for MLX90615 Infra Red Thermometer, which seems to be the predecesor of MLX90614 . There are significant differences in the register layout compared to MLX90614, but the functionality of the device is virtually identical. Acked-by:

Andreas Klinger authored
Honeywell mprls0025pa is a pressure sensor series. There are many different models with different pressure ranges, units and transfer functions. The range and transfer function need to be set up in the dt. Therefore new properties honeywell,pmin-pascal, honeywell,pmax-pascal, honeywell,transfer-function are introduced. Add dt-bindings.

After commit b8a1a4cd ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f4 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

The Invensense ICM-20600 is a 6-axis MotionTracking device that combines a 3-axis gyroscope and an 3-axis accelerometer. It is very similar to the ICM20602 imu which is already supported by the mpu6050 driver. The main difference is that the ICM-20600 has a different WHOAMI value. Signed-off-by:

Set the read_label() callback to return a friendly name provided in DT (firmware), in order to make in_{therm,voltage}X_label attributes show up in sysfs for userspace to consume a channel name. This is particularly useful for custom thermistors being attached to otherwise generically named GPIOs, where the name is known by the board DT. If the channel name isn't set in DT, use the datasheet_name hardcoded in the driver instead. Note that this doesn't fall back to fwnode_get_name() as that provides suboptimally readable names, with an @xx address suffix from board DT.

Marijn Suijten authored
Since the migration to fwnode_get_name in commit 4f47a236 ("iio: adc: qcom-spmi-adc5: convert to device properties") the resulting adc5_channel_prop::channel_name (renamed from datasheet_name in the previous patch) - which is propagated into iio_chan_spec::extend_name - was containing the DT node name including @xx suffix if a "label" property is not present, while adc5_channels::datasheet_name was thus far set by the macros but always remained unread. Put it to use instead of using a confusing name containing @xx in sysfs filenames (again, when "label" is not set). Signed-off-by:

iio_chan_spec::datasheet_name expects a channel/pin name on the hardware part, i.e. from its datasheet, instead of a friendly name from DT which typically describes the use of said channel. GPIO channels are commonly specialized in QCOM board DTS based on what a - typically thermistor - is connected to. Also rename adc5_channel_prop::datasheet_name to channel_name to that effect.

Marijn Suijten authored
As mentioned and discussed in [1] extend_name should not be used for full channel labels (and most drivers seem to only use it to express a short type of a channel) as this affects sysfs filenames, while the label name is supposed to be extracted from the *_label sysfs file instead. This appears to have been unclear to some drivers as extend_name is also used when read_label is unset, achieving an initial goal of providing sensible names in *_label sysfs files without noticing that sysfs filenames are (negatively and likely unintentionally) affected as well. Point readers of iio_chan_spec::extend_name to iio_info::read_label by mentioning deprecation and side-effects of this field.

Devices which may take a while to initialize during probe and which have no strong reason to probe synchronously can request asynchronous probing as default probe strategy. This can speed-up start times on some platforms. The KX022A gets probe delayed for at least two reasons. It enables the supply regulator, (which is likely to have ramp-up delay if it was disabled) and additionally it delays while the sensor itself is initializing. Changing to asynchronous probing may cause problems. Some of which are discussed in: https://lore.kernel.org/all/06db017f-e985-4434-8d1d-02ca2100cca0@sirena.org.uk/ Enable asynchronous probing for KX022A. Signed-off-by:

If the async probing appears to be an issue we can switch easily back to synchronous (or better yet, fix the actual problem). Enable asynchronous probing for BU27034. Signed-off-by:

As discussed in [1] it is more convenient to use a generic `channel` node name for ADC channels while storing a friendly - board-specific instead of PMIC-specific - name in the label, if/when desired to overwrite the channel description already contained (but previously unused) in the driver [2]. The same `channel` node name pattern has also been set in iio/adc/adc.yaml, but this generic binding is not inherited as base for qcom,spmi-vadc bindings due to not having any other generic elements in common, besides the node name rule and reg property. Replace the .* name pattern with the `channel` literal, but leave the label property optional for bindings to choose to fall back a channel label hardcoded in the driver [2] instead.

This driver uses the continuous mode of the chip and integration time can be configured through sysfs. The constants for calculating lux value differs between packaging so it uses different compatible string for the two versions "ti,opt4001-picostar" and "ti,opt4001-sot-5x3" since the device id is the same.
