* iio: accel: bmc150: set low default thresholdsSrinivas Pandruvada2014-11-161-2/+2
| | | | | | | | Set the threshold to low by default. With this thresholds any movement on the device with this sensor will generate event. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

* iio: accel: kxcjk-1013: Fix kxcjk10013_set_rangeDaniel Baluta2014-11-151-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, we get the new GSEL bits by OR-ing the old values with the new ones. This only works first time when the old values are 0. Startup: * GSEL0 = 0, GSEL1 = 0 Set range to 4G: (GSEL0 = 1, GSEL1 = 0) * GSEL0 = 0 | 1 = 1 * GSEL1 = 0 | 0 = 0 * correct Change range to 2G: (GSEL0 = 0, GSEL1 = 0) * GSEL0 = 1 | 0 = 1 * GSEL1 = 0 | 0 = 0 * wrong, GSEL0 should be 0 This has the nice effect that we can use the full scale range, exported in in_accel_scale_available.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If touchscreen mode is enabled and a conversion is requested on another channel, the result in the last converted data register can be a touchscreen relative value. Starting a conversion involves to do a conversion for all active channel. It starts with ADC channels and ends with touchscreen channels. Then if ADC_LCD register is not read quickly, its content may be a touchscreen conversion. To remove this temporal constraint, the conversion value is taken from the channel data register.

* | iio: sensors-core: st: Check st_sensors_set_drdy_int_pin()'s return valueLee Jones2014-08-301-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | Value from st_sensors_set_drdy_int_pin() is assigned to err here, but that stored value is not used before it is overwritten. To fix this we're enforcing a check on st_sensors_set_drdy_int_pin()'s return value and if it's an error, we're returning right away.

* | iio: adc: rockchip_saradc: remove unused variable in probeHeiko Stübner2014-08-301-1/+0
| | | | | | | | | | | | | | | | | | The rate variable in the probe function of the saradc is a remnant of a previous patch iteration. It is unused and thus produces a compile time warning. Therefore remove it. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
