2014-11-15iio: accel: kxcjk-1013: Fix kxcjk10013_set_rangeDaniel Baluta1-0/+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.

Add support for the BMI055 gyroscope sensor. BMI055 is a package consisting of an acceleration sensor and a gyroscope. This patch adds support for the gyroscope only. Spec downloaded from: http://ae-bst.resource.bosch.com/media/products/dokumente/bmi055/BST-BMI055-DS000-06.pdf The BMI055 gyroscope uses the same register definition as BMG160, but does not specify a temp register. However, the temp register seems to be working in the same way as for BMG160, so this patch does not remove the temp channel for BMI055.

2014-09-14iio: adc: at91: don't use the last converted data registerLudovic Desroches1-5/+7
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.

Hence, change this driver to support these chips too: BMI055 - combo chip (accelerometer part is identical to BMC150's) BMA255 - identical to BMC150's accelerometer BMA222E - 8 bit resolution BMA250E - 10 bit resolution BMA280 - 14 bit resolution Additionally: * add bmc150_accel_match_acpi_device() function to check that the device has been enumerated through ACPI; * rename bmc150_accel_acpi_gpio_probe() to bmc150_accel_gpio_probe() since the ACPI matching has been moved to the new function. Also, this will allow for the GPIO matching to be done against a device tree too, not only ACPI tree; * rename bmc150_scale_info struct member 'range' to 'reg_range' to be consistent with the naming convention used elsewhere in the driver and declare it u8, instead of int; * change CONFIG description to list all supported chips; Signed-off-by: Laurentiu Palcu <laurentiu.palcu@intel.com> Acked-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
