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: hid-sensors: select IIO_TRIGGERED_BUFFER under HID_SENSOR_IIO_TRIGGER

2021-05-10T13:01:48Z

During commit 067fda1c065ff ("iio: hid-sensors: move triggered buffer setup into hid_sensor_setup_trigger"), the iio_triggered_buffer_{setup,cleanup}() functions got moved under the hid-sensor-trigger module. The above change works fine, if any of the sensors get built. However, when only the common hid-sensor-trigger module gets built (and none of the drivers), then the IIO_TRIGGERED_BUFFER symbol isn't selected/enforced. Previously, each driver would enforce/select the IIO_TRIGGERED_BUFFER symbol. With this change the HID_SENSOR_IIO_TRIGGER (for the hid-sensor-trigger module) will enforce that IIO_TRIGGERED_BUFFER gets selected. All HID sensor drivers select the HID_SENSOR_IIO_TRIGGER symbol. So, this change removes the IIO_TRIGGERED_BUFFER enforcement from each driver.

iio: light: fix kconfig dependency bug for VCNL4035

2020-11-08T15:43:44Z

When VCNL4035 is enabled and IIO_BUFFER is disabled, it results in the following Kbuild warning: WARNING: unmet direct dependencies detected for IIO_TRIGGERED_BUFFER Depends on [n]: IIO [=y] && IIO_BUFFER [=n] Selected by [y]: - VCNL4035 [=y] && IIO [=y] && I2C [=y] The reason is that VCNL4035 selects IIO_TRIGGERED_BUFFER without depending on or selecting IIO_BUFFER while IIO_TRIGGERED_BUFFER depends on IIO_BUFFER. This can also fail building the kernel. Honor the kconfig dependency to remove unmet direct dependency warnings and avoid any potential build failures.

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: vcnl4000: Add buffer support for VCNL4010/20.

2020-05-03T13:53:57Z

The VCNL4010 and VCNL4020 chips are able to raise interrupts on data ready. Use it to provide triggered buffer support for proximity data. Those two chips also provide ambient light data. However, they are sampled at different rate than proximity data. As this is not handled by the IIO framework for now, and the sample frequencies of ambient light data are very low, do add buffer support for them.

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
