2015-01-30iio: add driver for Freescale MMA9553Irina Tirdea
Add support for Freescale MMA9553L Intelligent Pedometer Platform. The following functionalities are supported: - step counter (counts the number of steps using a HW register) - step detector (generates an iio event at every step the user takes) - activity recognition (rest, walking, jogging, running) - speed - calories - distance To get accurate pedometer results, the user's height, weight and gender need to be configured. The specifications can be downloaded from: http://www.freescale.com/files/sensors/doc/ref_manual/MMA955xLSWRM.pdf http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf Signed-off-by: Irina Tirdea <irina.tirdea@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

2015-01-27iio: accel: mma9551: split driver to expose mma955x apiIrina Tirdea
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.

2015-01-27iio: accel: mma9551: Add runtime pm supportIrina Tirdea
Add support for runtime pm to reduce the power consumed by the device when not used. If CONFIG_PM is not enabled, the device will be powered on at init and only powered off on system suspend. If CONFIG_PM is enabled, runtime pm autosuspend is used: - for raw reads will keep the device on for a specified time - for events it will keep the device on as long as we have at least one event active Signed-off-by: Irina Tirdea <irina.tirdea@intel.com> Reviewed-by: Vlad Dogaru <vlad.dogaru@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-testing Jonathan writes: First round of IIO new drivers, cleanups and functionality for the 3.20 cycle take 2 Updated pull request with Daniel's fix on top for the power management Kconfig changes that had snuck in since last update of the IIO tree worked it's way through from mainline. Original pull message New device support * jsa1212 proxmity / ambient light sensor * SM08500 supported added to the kxcjk-1013 accelerometer driver * KMX61 Accelerometer/Magnetometer. This took a somewhat rocky path being first merged, then reverted for a rewrite after a discussion of how to support additional functionality and finally being merged prior to some last reviews coming in, with resultant follow up patches. * Freescale mma9551l driver (minor follow up warning supression patch). * Semtech SX9500 proximity device driver. * ak8975 gains support for ak09911 and ak09912 and drop the standalone driver for the ak09911. New functionality * Dummy driver gains some virtual registers making it more flexible. * IIO_ACTIVITY channel types, with modifiers running, walking etc. This is to support on chip motion clasifiers. As such it is in the form of a confidence percentage. The only devices so far only do binary decisions but this gives us room when other devices give more nuanced clasification. * IIO_EV_DIR_NONE type for events where there is no obvious direction. First case is step detection. * IIO_STEPS channel type for pedometers. * ENABLE mask element used to control turning on counting types such as the pedometer that need a 'start point'. * INSTANCE event type to support things that happen once. * info element for height calibration (used in various motion estimation algorithms). Note heigh tof use * dummy driver demonstration of the use of all the new bits above. * event monitor support for the new events. * inv_mpu6050 gains an i2c mux to allow bypassing the device to access additional devices connected on the other side of it. Note that in Windows these are handled by firmware on the device and not exposed directly. * inv_mpu6050 gains ACPI enumeration. * inkern interface gains iio_write_channel_raw to allow in kernel users of DAC functionality via a simple wrapper. * Document input current readings in the ABI docs. * Add an error message when we get an out of range error in device tree processing for the in kernel interfaces. Basically a device tree debugging aid. * Add a sanity check that a scan index for a channel is unique during registration. There to help catch bugs as this should never happen in a bug free driver. Cleanups and fixlets A rework of buffer registration from Lars - a precursor to some other upcoming new stuff (a few patches from others rolled in here as well). * Ensure all drivers register the same channels for the device and buffer. * Move buffer registration into the core rather than using the old two step approach. Now we have simple ways of using a unified set channels for both without requiring channels be exposed by both interface, this removes a fair bit of boilerplate. * Stop sca3000 and ad5933 (both in staging) enabling buffer channels by default. It has long be convention in IIO to startup with no channels enabled and leave it up to userspace to say what goes in the buffer. Getting rid of these allows us to drop export of iio_scan_mask_set. * Drop get_bytes_per_datum from iio_buffer_access_funcs as not been used for a while. * Allocate standard buffer attributes in the core rather than in every driver with a buffer. * Make the length attribute read only when a driver is not able to set the length. * Drop the get_length callback for buffers as it is already available in struct iio_buffer. * Drop an unused arguement form iio_kfifo_allocate and add devm allocator for it. * some kconfig entries gain anotation with the resulting module name. * Fix a resulting compile issue in dummy driver due to a stub taking wrong parameters as a result of the above rework. * Fix an off by 2 error in copying the core assigned buffer attributes. Other cleanups, * Trivial space before comma fixups. * ak8975 fixlets - none critical. Rework to allow more device support. * Drop unnecessary sizeof(u8) calls. * bmp280 - refactor the compensation code to reduce copy operations and code length. A second patch futher optimized this and performed some other minor cleanups. * kxcjk-1013 - various power control cleanups to avoid unnecessary enable / disable of device. Make sure it is only controlled at all if CONFIG_PM is enabled. Also som cleanups of error paths. * Small cleanups in adf4530 driver - pointless message and unnecessary braces. * Clarifiy the proximity ABI docs to make it clear it should get bigger as we move futher away. * Drop a misleading comment form industrialio-core.c * Trivial white space cleanups. * sca3000 looses an unused debug function. * Fix char unsigned ordering in ad8366 * Increase the sleep time in ad9523 to make it predictable (value didn't really matter so make it more than 20 msecs) * mxs-lradc touchscreen property cleanups in device tree are fixed to ensure the meet all the 'interesting' documentation. * A couple of cleanups for the staging ad5933 driver to avoid unnecessary conversion to a processed temperature vlaue in kernel and remove platform data form the state structure as not needed after probe. * Fix a wrong scale factor in the docs. Misc * Add IIO include files to the maintainers entry.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging Pull staging driver updates from Greg KH: "Here's the big staging tree pull request for 3.19-rc1. We continued to delete more lines than were added, always a good thing, but not at a huge rate this release, only about 70k lines removed overall mostly from removing the horrid bcm driver. Lots of normal staging driver cleanups and fixes all over the place, well over a thousand of them, the shortlog shows all the horrid details. The "contentious" thing here is the movement of the Android binder code out of staging into the "real" part of the kernel. This is code that has been stable for a few years now and is working as-is in the tens of millions of devices with no issues. Yes, the code is horrid, and the userspace api leaves a lot to be desired, but it's not going to change due to legacy issues that we have no control over. Because so many devices and companies rely on this, and the code is stable, might as well promote it out of staging. This was all discussed at the Linux Plumbers conference, and everyone participating agreed that this was the best way forward. There is work happening to replace the binder code with something new that is happening right now, but I don't expect to see the results of that work for another year at the earliest. If that ever happens, and Android switches over to it, I'll gladly remove this version. As for maintainers, I'll be glad to maintain this code, I've been doing it for the past few years with no problems. I'll send a MAINTAINERS entry for it before 3.19-final is out, still need to talk to the Google developers about if they are willing to help with it or not, last I checked they were, which was good.

2014-09-14iio: accel: kxcjk-1013: add support for kxtj2-1009Daniel Baluta
This patch adds support for KXTJ2-1009 3-axis acceleromenter sensor. KXTJ2-1009 uses the same register definitions as KXCJK-1013. The specification for KXTJ2-1009 can be downloaded from: http://www.kionix.com/sites/default/files/KXTJ2-1009%20Specifications%20Rev%204.pdf Reviewed-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> Signed-off-by: Daniel Baluta <daniel.baluta@intel.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2014-09-13iio: accel: BMC150: add support for other Bosch chipsLaurentiu Palcu
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>

2014-08-30iio: accel: BMC150: fix issues when CONFIG_PM_RUNTIME is not setLaurentiu Palcu
When CONFIG_PM_RUNTIME is not set, the following issues are seen: * warning message at compilation time: warning: 'bmc150_accel_get_startup_times' defined but not used [-Wunused-function] * bmc150_accel_set_power_state() will always fail and reading the accelerometer data is impossible; This occurs because of the call to pm_runtime_put_autosuspend calls __pm_runtime_suspend which returns -ENOSYS.
