2014-10-25iio:humidity:si7020: cleanup read_raw and probeHartmut Knaack1-5/+3
When reading temperature or humidity values, a shift of two bits to the right needs to be applied, and only for the humidity channel a mask of the lower 12 bits needs to be applied. This reduces code repetition. During probe, i2c_set_clientdata() was used, although its counterpart was not, so drop it.

2014-10-25iio: inkern: Add of_xlate function to struct iio_infoIvan T. Ivanov2-5/+36
When #iio-cells is greater than '0', the driver could provide a custom of_xlate function that reads the *args* and returns the appropriate index in registered IIO channels array. Add simple translation function, suitable for the most 1:1 mapped channels in IIO chips, and use it when driver did not provide custom implementation. Signed-off-by: Ivan T.

2014-10-04IIO: add si7020 driverDavid Barksdale3-0/+174
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.

Older Rockchip SoCs, at least the rk3066, used a slightly modified saradc for temperature measurements. This so called tsadc does not contain any active parts like temperature interrupts and only supports polling the current temperature. The returned voltage can then be converted by a suitable thermal driver to and actual temperature and used for thermal handling.
