Revert "iio: hid-sensor-als: Add light color temperature support"

2023-12-19T07:08:20Z

This reverts commit 5f05285df691b1e82108eead7165feae238c95ef. This commit assumes that every HID descriptor for ALS sensor has presence of usage id ID HID_USAGE_SENSOR_LIGHT_COLOR_TEMPERATURE. When the above usage id is absent, driver probe fails. This breaks ALS sensor functionality on many platforms. Till we have a good solution, revert this commit.

iio: hid-sensor-als: Add light chromaticity support

2023-09-24T12:31:33Z

In most cases, ambient color sensors also support the x and y light colors, which represent the coordinates on the CIE 1931 chromaticity diagram. Thus, add light chromaticity x and y.

HID: hid-sensor-custom: Allow more custom iio sensors

2022-12-20T14:24:57Z

The known LUID table for established/known custom HID sensors was limited to sensors with "INTEL" as manufacturer. But some vendors such as Lenovo also include fairly standard iio sensors (e.g. ambient light) in their custom sensors. Expand the known custom sensors table by a tag used for the platform device name and match sensors based on the LUID as well as optionally on model and manufacturer properties.

iio: Add relative sensitivity support

Some hid sensors may use relative sensitivity such as als sensor. This patch adds relative sensitivity checking for all hid sensors. Signed-off-by: Ye Xiang Acked-by: Jiri Kosina Link: https://lore.kernel.org/r/20210207070048.23935-2-xiang.ye@intel.com Signed-off-by: Jonathan Cameron

HID: hid-sensor-custom: Add custom sensor iio support

2021-01-22T08:52:02Z

Currently custom sensors properties are not decoded and it is up to user space to interpret. Some manufacturers already standardized the meaning of some custom sensors. They can be presented as a proper IIO sensor. We can identify these sensors based on manufacturer and serial number property in the report. This change is identifying hinge sensor when the manufacturer is "INTEL". This creates a platform device so that a sensor driver can be loaded to process these sensors.

iio: hid-sensor-hub: Implement batch mode

2017-05-16T18:44:01Z

HID sensor hubs using Integrated Senor Hub (ISH) has added capability to support batch mode. This allows host processor to go to sleep for extended duration, while the sensor hub is storing samples in its internal buffers. 'Commit f4f4673b7535 ("iio: add support for hardware fifo")' implements feature in IIO core to implement such feature. This feature is used in bmc150-accel-core.c to implement batch mode. This implementation allows software device buffer watermark to be used as a hint to adjust hardware FIFO. But HID sensor hubs don't allow to change internal buffer size of FIFOs. Instead an additional usage id to set "maximum report latency" is defined. This allows host to go to sleep upto this latency period without getting any report. Since there is no ABI to set this latency, a new attribute "hwfifo_timeout" is added so that user mode can specify a latency. This change checks presence of usage id to get/set maximum report latency and if present, it will expose hwfifo_timeout. Signed-off-by: Srinivas Pandruvada Signed-off-by: Jonathan Cameron

iio: hid-sensor-rotation: Add geomagnetic orientation sensor hid support.

2017-05-07T11:22:33Z

Geomagnetic orientation(AM) sensor is one kind of orientation 6dof sensor. It gives the device rotation in respect to the earth center and the magnetic north. The sensor is implemented through use of an accelerometer and magnetometer do not use gyroscope. It is a standard HID sensor. More information can be found in: http://www.usb.org/developers/hidpage/HUTRR59_-_Usages_for_Wearables.pdf Geomagnetic orientation(AM) sensor and dev rotation sensor have same channel and share channel usage id. So the most of the code for relative orientation sensor can be reused. Signed-off-by: Song Hongyan Signed-off-by: Jonathan Cameron
