* iio: accel: fix Kconfig warningLinus Walleij2017-01-231-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 762227721fe6225be5b6d233ef681aea5871f5f3 "iio: accel: st_accel: handle deprecated bindings" attempted to be smart and let users use the old I2C driver and the new SPI driver, or the old SPI driver and the new I2C driver in combination for the LIS3LV02, and put the restrictions on the I2C and SPI subdrivers not not be combined with the old subdrivers. This doesn't work since the IIO ST accel top-level component selects the I2C and SPI subdrivers, resulting in the following Kconfig noise: warning: (IIO_ST_ACCEL_3AXIS) selects IIO_ST_ACCEL_I2C_3AXIS which has unmet direct dependencies (IIO && !SENSORS_LIS3_I2C && IIO_ST_ACCEL_3AXIS && IIO_ST_SENSORS_I2C) warning: (IIO_ST_ACCEL_3AXIS) selects IIO_ST_ACCEL_SPI_3AXIS which has unmet direct dependencies (IIO && !SENSORS_LIS3_SPI && IIO_ST_ACCEL_3AXIS && IIO_ST_SENSORS_SPI) (...) This fixes the issue by putting the dependencies directly in the top-level component instead, so that it never gets to select its unselectable subcomponent.

* iio: accel: st_accel: handle deprecated bindingsLinus Walleij2017-01-101-0/+2
| | | | | | | | | | | | | | | | | | | The earlier deployed LIS3LV02DL driver had already defined a few DT bindings that need to be supported by the new more generic driver and listed as compatible but deprecated bindings in the documentation. After this we can start to activate the new driver with the old systems where applicable. As part of this enablement: make us depend on the old drivers not being in use so we don't get a kernel with two competing drivers.

* iio: accel: kxsd9: Add triggered buffer handlingLinus Walleij2016-09-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As is custom with all modern sensors, add a clever burst mode that will just stream out values from the sensor and provide it to userspace to do the proper offsetting and scaling. This is the result when tested with an HRTimer trigger: $ generic_buffer -a -c 10 -n kxsd9 -t foo /sys/bus/iio/devices/iio:device1 foo 0.371318 0.718680 9.869872 1795.000000 97545896129 -0.586922 0.179670 9.378775 2398.000000 97555864721 -0.299450 0.179670 10.348992 2672.000000 97565874055 0.371318 0.335384 11.103606 2816.000000 97575883240 0.179670 0.574944 10.540640 2847.000000 97585862351 0.335384 0.754614 9.953718 2840.000000 97595872425 0.179670 0.754614 10.732288 2879.000000 97605882351 0.000000 0.754614 10.348992 2872.000000 97615891832 -0.730658 0.574944 9.570422 2831.000000 97625871536 0.000000 1.137910 10.732288 2872.000000 97635881610 Columns shown are x, y, z acceleration, so a positive acceleration of ~9.81 (shaky due to bad calibration) along the z axis. The fourth column is the AUX IN which is floating on this system, it seems to float up to the 2.85V VDD voltage. To be able to cleanup the triggered buffer, we need to add .remove() callbacks to the I2C and SPI subdrivers and call back into an exported .remove() callback in the core.

We export the common probe and add a local header file for the functionality shared between the main driver and the transport driver.

This set comprises those not dependent on patches in the 4.5 merge cycle. A second set will follow shortly with ones that are. * core in kernel interfaces - fix a possible NULL dereference that is a theoretical possibility via odd usage of iio_channel_release. Pretty much a hardening of the interface, but observed in the wild with the twl4030_charger driver. * acpi-als - report the data as processed as it is in lux. This fixes a wrong use of the IIO ABI. However, old _raw version retained to avoid breaking any userspace in the wild that is relying on that (none known but it doesn't hurt us much to retain it) * ade7753 - fix some error handling to avoid use of unitialized data. * ltr501 - use a signed return type for ltr501_match_samp_freq so as to allow returning of an error code. * mcp4725 - set name field of struct iio_dev to ensure the sysfs name attribute doesn't give NULL. * mpl115 - temperature offset sign is wrong. * stk8ba50 - IIO_TRIGGER dependency added * ti_am335x_adc - Label buffer as a software buffer. It's actually a hybrid of a true hardware buffer feeding a kfifo, but the meaning of these fields has changed a little recently and in this case it should be labeled a software buffer ensure it is allowed to use the kfifo. * vf610_adc - HAS_IOMEM dependency

| | | | | | | | | | | | | | Freescale has the MMA955xL family of devices that use the same communication protocol (based on i2c messages): http://www.freescale.com/files/sensors/doc/data_sheet/MMA955xL.pdf. To support more devices from this family, we need to split the mma9551 driver so we can export the common functions that will be used by other mma955x drivers.

| | | | | | | | | | | | | | | Add support for Freescale MMA9551L Intelligent Motion-Sensing Platform. The driver supports raw reads for acceleration and inclination, as well as configuring inclination rate-of-change events. The events can be used similarly to an Android sensor Tilt event.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The following chips are either similar or have only the resolution different. 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>
