2021-05-10iio: hid-sensors: select IIO_TRIGGERED_BUFFER under HID_SENSOR_IIO_TRIGGERAlexandru Ardelean1-1/+0
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.

2020-09-03iio: humidity: Add TI HDC20x0 supportEugene Zaikonnikov1-0/+10
Add driver support for HDC2010/2080 series devices and sysfs documentation for their heater element. HDC2010 is an integrated high-accuracy humidity and temperature sensor with very low power consumption. The device includes a resistive heating element. The temperature range is -40C to 125C with 0.2C accuracy. Humidity measurement is 0 to 100% with 2% RH accuracy.

2015-05-10iio: Allow compile test of GPIO consumers if !GPIOLIBGeert Uytterhoeven1-1/+1
The GPIO subsystem provides dummy GPIO consumer functions if GPIOLIB is not enabled. Hence drivers that depend on GPIOLIB, but use GPIO consumer functionality only, can still be compiled if GPIOLIB is not enabled. Relax the dependency on GPIOLIB if COMPILE_TEST is enabled, where appropriate.

2014-10-04IIO: add si7020 driverDavid Barksdale1-0/+10
This patch adds support to the Industrial IO subsystem for the Silicon Labs Si7013/20/21 Relative Humidity and Temperature Sensors. Website: http://www.silabs.com/products/sensors/humidity-sensors/Pages/si7013-20-21.aspx These are i2c devices which measure relative humidity and temperature and all use the same protocol. The Si7013 has an additional input with programmable linearization which is not supported because that's complicated and I didn't need it. Signed-off-by: David Barksdale <dbarksdale@uplogix.com> -- Changes since v1: * Renamed to si7020 and replaced Si701x/2x with Si7013/20/21. * Removed unneeded mutex. * Pre-computed floating-point constant expressions. * Removed address_list and I2C_CLASS_HWMON. Changes since v2: * Return correct raw sensor values. * Rename dev variable to indio_dev. * Issue a software reset command during probe. * Un-broke string literal. Changes since v3: * enum changed to #define Signed-off-by: Jonathan Cameron <jic23@kernel.org>
