iio:proximity:sx9360: Add sx9360 support

2022-01-23T18:03:33Z

A simplified version of SX9324, it only have one pin and 2 phases (aka channels). Only one event is presented. Signed-off-by: Gwendal Grignou Reviewed-by: Stephen Boyd Link: https://lore.kernel.org/r/20220101203800.290387-2-gwendal@chromium.org Signed-off-by: Jonathan Cameron

iio:proximity:sx9324: Add SX9324 support

2022-01-23T18:03:33Z

Semtech SAR sensor SX9324 is an evolution of the SX9310: It has 4 phases that can be configured to capture and process data from any of 3 CS pins and provide independent detection: proximity, table proximity or body proximity.

iio:proximity:sx9310: Extract common Semtech sensor logic

2022-01-23T18:03:33Z

Before adding new Semtech sensors, move common logic to all Semtech SAR sensor in its own file: - interface with IIO subsystem, - interrupt management, - channel access conrol, - event processing. The change adds a bidirectional interface between sx93xx and sx_common. The change is quite mechanical, as the impacted functions are moved and renamed.

iio: proximity: Add a ChromeOS EC MKBP proximity driver

2021-03-25T19:13:50Z

Add support for a ChromeOS EC proximity driver that exposes a "front" proximity sensor via the IIO subsystem. The EC decides when front proximity is near and sets an MKBP switch 'EC_MKBP_FRONT_PROXIMITY' to notify the kernel of proximity. Similarly, when proximity detects something far away it sets the switch bit to 0. For now this driver exposes a single sensor, but it could be expanded in the future via more MKBP bits if desired.

iio: proximity: Add driver support for vcnl3020 proximity sensor

2020-05-21T18:12:42Z

Proximity sensor driver based on light/vcnl4000.c code. For now supports only the single on-demand measurement. The VCNL3020 is a fully integrated proximity sensor. Fully integrated means that the infrared emitter is included in the package. It has 16-bit resolution. It includes a signal processing IC and features standard I2C communication interface. It features an interrupt function. Datasheet: http://www.vishay.com/docs/84150/vcnl3020.pdf Signed-off-by: Ivan Mikhaylov Reviewed-by: Andy Shevchenko Signed-off-by: Jonathan Cameron

Add SEMTECH SX9310/9311 driver. The device has the following entry points: Usual frequency: - sampling_frequency - sampling_frequency_available Instant reading of current values for different sensors: - in_proximity0_raw - in_proximity1_raw - in_proximity2_raw - in_proximity3_comb_raw and associated events in events/ Signed-off-by: Gwendal Grignou Signed-off-by: Enrico Granata Signed-off-by: Daniel Campello Signed-off-by: Jonathan Cameron

iio: ping: add parallax ping sensors

2019-12-01T10:23:04Z

Add support for parallax ping and laser ping sensors with just one pin for trigger and echo signal. This driver is based on srf04. In contrast to it it's necessary to change direction of the pin and to request the irq just for the period when the echo is rising and falling. Because this adds a lot of cases there is this individual driver for handling this type of sensors. Add a new configuration variable CONFIG_PING to Kconfig and Makefile. Julia reported an issue with failing to unlock a mutex in some error paths. Signed-off-by: Andreas Klinger Reported-by: kbuild test robot Reported-by: Julia Lawall Signed-off-by: Jonathan Cameron

iio: proximity: Add driver support for ST's VL53L0X ToF ranging sensor.

2018-09-22T15:42:56Z

This driver was originally written by ST in 2016 as a misc input device driver, and hasn't been maintained for a long time. I grabbed some code from it's API and reformed it into an iio proximity device driver. This version of driver uses i2c bus to talk to the sensor and polling for measuring completes, so no irq line is needed. It can be tested with reading from /sys/bus/iio/devices/iio:deviceX/in_distance_input Signed-off-by: Song Qiang Reviewed-by: Rob Herring Signed-off-by: Jonathan Cameron
