iio: light: Added AMS tsl2591 driver implementation

2021-05-17T12:49:06Z

Driver implementation for AMS/TAOS tsl2591 ambient light sensor. This driver supports configuration via device tree and sysfs. Supported channels for raw infrared light intensity, raw combined light intensity and illuminance in lux. The driver additionally supports iio events on lower and upper thresholds. This is a very-high sensitivity light-to-digital converter that transforms light intensity into a digital signal.

iio: light: as73211: New driver

2020-09-03T18:40:40Z

Support for AMS AS73211 JENCOLOR(R) Digital XYZ Sensor. This driver has no built-in trigger. In order for making triggered measurements, an external (software) trigger driver like iio-trig-hrtimer or iio-trig-sysfs is required. The sensor supports single and continuous measurement modes. The latter is not used by design as this would require tight timing synchronization between hardware and driver without much benefit.

iio: light: Add support for Azoteq IQS621/622 ambient light sensors

2020-03-27T08:25:56Z

This patch adds support for the Azoteq IQS621 and IQS622 ambient light sensors, both of which can report a four-bit representation of ambient light intensity. The IQS621 can additionally report illuminace directly in units of lux, while the IQS622 can report a four-bit representation of infrared light intensity. Furthermore, the IQS622 can report a unitless measurement of a target's proximity to the device. Signed-off-by: Jeff LaBundy Reviewed-by: Jonathan Cameron Signed-off-by: Lee Jones

iio: light: add Dyna-Image AL3010 driver

Based on: - 3320A in-kernel driver - https://www.spinics.net/lists/linux-iio/msg25145.html - https://lore.kernel.org/patchwork/patch/684179/ I decided to keep it aside of AL3320A due to different approach and much simpler design of 3010.

iio: light: Add a driver for Sharp GP2AP002x00F

2020-02-14T12:08:19Z

This driver handles two different Sharp sensors that have been proposed for merging to the mainline kernel over the years, and already has a limited proximity-only driver in the input subsystem. These components are completely different from the confusingly similarly named Sharp GP2AP020A00F, for which we have a driver in drivers/iio/light/gp2ap020a00f.c The two components GP2AP002A00F and GP2AP002S00F are distinctively different but similar: they share the same set of registers but differ slightly in the I2C protocol. Instead of the approach by the previous input driver, we create a combined IIO proximity and light sensor driver. The plan is to merge this driver and delete the input driver. The pieces for the driver are picked all over the place after researching and grepping through a few different vendor trees and driver submissions. We merge it under the light sensors because: - It has similarities with the Capella CM3605 light sensor and proximity driver which is there. - It is related to the GP2AP020A00F driver which is also there. This driver was tested with the Samsung GT-S7710 mobile phone which has the GP2AP002S00F proximity sensor mounted. The suspend/resume cycle will disable the interrupt from the sensor. If someone would desire to use this interrupt for wakeup, the driver will need modifications.
