Add 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. The following differences have been identified: - RAM/EEPROM/SLEEP access opcodes are different - RAM/EEPROM registers are at different offsets - EEPROM emissivity and configuration registers are at different offsets - EEPROM configuration register bits are shuffled around - EEPROM emissivity settings are 14 bit on MLX90615 , 16 bit on MLX90614 - MLX90615 can only ever support one sensor, MLX90614 could support two - FIR filter is set to fixed settings on MLX90615 - IIR filter coefficients are different This patch fills in the MLX90615 specific description and quirk handling. The IIR filter coefficients were provided by Melexis as follows: 0b0000 - Forbidden value 0b0001 - 100% - settling time = refresh rate = 205ms (around 5Hz) 0b0010 - 50% - settling time = 2050ms (around 0.5Hz) 0b0011 - 33% - settling time = 36900ms (around 0.3Hz) 0b0100 - 25% - settling time = 5125ms (around 0.2Hz) 0b0101 - 20% - settling time = 6355ms (around 0.15Hz) 0b0110 - 17% - settling time = 7790ms (around 0.13Hz) 0b0111 - 14% - settling time = 9225ms (around 0.1Hz) 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.

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.

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.

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:

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.
