iio: light: hid-sensor-als: Add duplicate IIO_LIGHT channel

2016-12-30T17:06:34+00:00

There is one light sensor type defined in the sensor hub specification, which has one Illuminance field. It doesn't distinguish between ambient light sensor or color sensor. Currently it is presented as IIO_INTENSITY channel. There are some user spaces specifically looking for IIO_LIGHT channel. To satisfy such user spaces this change also add a duplicate IIO_LIGHT channel. The units of measurement of Illuminance field is Lux, so it is still compatible to IIO ABI.

iio: light: hid-sensor-als.c: Fix memory leak in probe()

2015-05-17T08:10:05+00:00

'channels' is allocated via kmemdup and it is never freed in the subsequent error paths. Use 'indio_dev->channels' directly instead, so that we avoid such memory leak problem. Signed-off-by: Fabio Estevam Reviewed-by: Srinivas Pandruvada Signed-off-by: Jonathan Cameron

iio: light: hid-sensor-als: Constify platform_device_id

2015-05-10T19:31:46+00:00

The platform_device_id is not modified by the driver and core uses it as const. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Jonathan Cameron

HID: hid-sensor-hub: Extend API for async reads

2015-02-23T14:16:37+00:00

Add additional flag to read in async mode. In this mode the caller will get reply via registered callback for capture_sample. Callbacks can be registered using sensor_hub_register_callback function. The usage id parameter of the capture_sample can be matched with the usage id of the requested attribute. Signed-off-by: Srinivas Pandruvada Acked-by: Jonathan Cameron Signed-off-by: Jiri Kosina

iio: hid-sensor-als: Introduce PM

2015-01-25T22:55:47+00:00

Use common hid sensor iio pm functions. Also the poll time read and wait is part of power up function of hid sensor iio pm function, so remove from the client drivers. Signed-off-by: Srinivas Pandruvada Signed-off-by: Jonathan Cameron

iio: remove .owner field for driver using module_platform_driver

2014-08-26T20:08:38+00:00

This patch removes the .owner field for drivers which use the platform_driver_register api because this is overriden in _platform_driver_register. Signed-off-by: Sanjeev Sharma Signed-off-by: Jonathan Cameron

iio: hid-sensor-als: Fix return values

2014-07-05T10:07:38+00:00

IIO_CHAN_INFO_SAMP_FREQ and IIO_CHAN_INFO_HYSTERESIS cases ignored the actual return values (which could be -EINVAL) and instead returned IIO_VAL_INT_PLUS_MICRO always. Return the actual value obtained from the functions. Both functions return IIO_VAL_INT_PLUS_MICRO upon success. Signed-off-by: Sachin Kamat Cc: Srinivas Pandruvada Signed-off-by: Jonathan Cameron

iio: hid-sensors: ALS: Raw read support

2014-05-05T09:59:51+00:00

Added support for raw reading of channel. If the sensor is powered off, it will turn on for reading value. Signed-off-by: Srinivas Pandruvada Signed-off-by: Jonathan Cameron

iio: hid-sensors: Add API to power on/off

2014-05-05T09:59:49+00:00

Added an API to allow client drivers to turn ON and OFF sensors for quick read. Added data_read as counting varaible instead of boolean, so that sensor is powered off only when last user released it. Signed-off-by: Srinivas Pandruvada Signed-off-by: Jonathan Cameron
