2024-10-15iio: light: vl6180: Add support for Continuous ModeAbhash Jha
Added support for getting continuous readings from vl6180 using triggered buffer approach. The continuous mode can be enabled by enabling the buffer. Also added a trigger and appropriate checks to see that it is used with this device.

2024-10-15iio: light: vl6180: Added Interrupt support for single shot accessAbhash Jha
The interrupts are serviced in the `vl6180_measure` function when the irq_handler signals that the reading is complete. We now can read asynchronously if `client->irq` is set.

The veml7700 contains the same sensor as the veml6030 in a different package with no interrupt line and no pin to select the I2C address. To handle the lack of the interrupt line and profit from the existing support for the veml6030, add a specific iio_chan_spec with no (num_)event_spec(s), and register the device's info from the veml6030_info_no_irq struct.

2024-10-15iio: light: veml6035: fix read_avail in no_irq case for veml6035Javier Carrasco
The iio_info is identical for veml6030 and veml6035. Moreover, veml6035_info_no_irq is missing the initialization of the read_avail member, which is actually a bug if no irq is provided. Instead of adding the missing initialization, remove the device-specific iio_info and use the existing one for the veml6030.

2024-10-10iio: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/iio/ to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in several files.

2024-08-17iio: light: ltr390: Add ALS channel and support for gain and resolutionAbhash Jha
Add new ALS channel and allow reading lux and scale values. Also provide gain and resolution configuration for ALS channel. Add automatic mode switching between the UVS and ALS channel based on which channel is being accessed. The default mode in which the sensor start is ALS mode.

2024-08-17iio: light: noa1305: Fix up integration time look upMarek Vasut
The current code is always iterating over two fields in the noa1305_int_time_available array. Fix iteration limit, which has to be halved to avoid out of bounds access in case the value that is being looked up is not in the array.

2024-08-10iio: light: apds9960: Add proximity and gesture offset calibrationAbhash Jha
Proximity and gesture offset registers perform offset correction to improve cross-talk performance. Added `calibbias` to the proximity and gesture channels. Provided facility to set calibbias based on the channel number.

2024-08-03iio: light: stk3310: add support for stk3013Kaustabh Chakraborty
Add support for Sensortek's STK3013 in the driver. The part bears the product ID 0x31. As seen in [1], Sensortek lists STK3013 as a proximity sensor. But it has been experimentally observed that they do have ambient light sensing capabilities. Furthermore, [2] implements a proximity and ambient light sensor driver for STK3x1x devices, which is also indicative of the fact that these parts are also ambient light sensors.

In order to allow newer devices which are compatible with existing sensors, issuing a warning for an unknown chipid indicates that something has gone wrong with the init process, which isn't ideal. Swap it with a friendlier info message to get things right.

2024-08-03iio: light: ROHM BH1745 colour sensorMudit Sharma
Add support for BH1745, which is an I2C colour sensor with red, green, blue and clear channels. It has a programmable active low interrupt pin. Interrupt occurs when the signal from the selected interrupt source channel crosses set interrupt threshold high or low level. Interrupt source for the device can be configured by enabling the corresponding event. Interrupt latch is always enabled when setting up interrupt. Add myself as the maintainer for this driver in MAINTAINERS.
