2015-04-07Merge 4.0-rc7 into staging-nextGreg Kroah-Hartman1-1/+1
We want those fixes (iio primarily) into the -next branch to help with merge and testing issues. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2015-03-07iio: fix drivers that check buffer->scan_maskOctavian Purdila1-1/+1
If the in-kernel push interface is used we may have a different masks on the device buffer and the kernel buffer and in this case the device should generate data for the reunion of the buffers, which is available at indio_dev->active_scan_mask. Compiled tested only except for bmc150-accel which was tested at runtime with the hardware.

2015-02-22iio: improve usage of gpiod APIUwe Kleine-König1-5/+1
Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions) which appeared in v3.17-rc1, the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for outputs.

2014-12-04iio / PM: Replace CONFIG_PM_RUNTIME with CONFIG_PMRafael J. Wysocki1-2/+2
After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks depending on CONFIG_PM_RUNTIME may now be changed to depend on CONFIG_PM. Replace CONFIG_PM_RUNTIME with CONFIG_PM everywhere under drivers/iio/. Signed-off-by: Rafael J.

2014-11-16iio: gyro: bmg160: Send x, y and z motion separatelySrinivas Pandruvada1-2/+19
This chip is capable to identify motion across x, y and z axes. So send different events. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2014-11-16iio: gyro: bmg160: Don't let interrupt mode to be open drainSrinivas Pandruvada1-0/+16
Change the mode to push/pull type instead of open drain as some platforms fails to drive the GPIO pin with open drain. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2014-11-16iio: gyro: bmg160: Error handling when mode set failsSrinivas Pandruvada1-1/+13
When mode set fails due to some transient failures, it will atleast reset the state of runtime usage count and also let the runtime suspend retry from the driver framework. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2014-09-14iio: gyro: bmi055 gyro sensor driverIrina Tirdea1-12/+27
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: gyro: bmg160: only set power state if PM_RUNTIME is definedIrina Tirdea1-0/+2
When CONFIG_PM_RUNTIME is not defined and bmg160 tries to power off the device, bmg160_set_power_state will call pm_runtime_put_autosuspend, which is not implemented (wil return -ENOSYS). Only call bmg160_set_power_state when CONFIG_PM_RUNTIME is defined.
