mma8452_set_freefall_mode can return -ve value in case if i2c_smbus_read_byte_data fails. This function is called from mma8452_probe, and returning -ve value from probe indicates probe failure. Need to call iio_triggered_buffer_cleanup & iio_trigger_cleanup in this case. Signed-off-by:

The tree has been in the same location for a long time. Putting it in MAINTAINERS makes it easy for those new to, or less familiar with IIO to find the correct tree to base patches on. Mostly basing on staging-next is fine as well unless working on a very active driver. Signed-off-by: -

Retire this venerable driver as the basic support is now in the generic st-sensors accelerometer driver. There are a few missing features in the new driver: * Threshold events. * Access to the calibration adjustment registers (patch shortly) In exchange it brings a cleaner and more maintainable code base that actually gets tested more than once every few years. I'll actually be suprised if anyone other than me has a board with one of these on that is running an up to date kernel. Signed-off-by: -

Time to finally kill off the venerable (it was one of my first drivers) lis3l02dq driver in favour of adding support in the st sensors framework. This does loose us the event support that driver always had, but I think that will reappear at some point and in the meantime the maintenance advantages of dropping the 'special' driver for this one part outweigh the issues. It's worth noting this part is ancient and I may well be the only person who still has any on hardware running recent kernels. It has a few 'quirks'. - No WAI register so that just became optional. - A BDU option that really does block updates. Completely. Whatever you do, you don't get any more data with it set. It is documented the same as more modern parts but I presume they are actually clearing for updates after a read of both bytes! - Fixed scale. - It's too quick. Even at slowest rate (280Hz) I can't read out fast enough on my board (stargate 2) to beat new data coming in. Linus' repeat read patch doesn't help in this case. It just means I get 10 readings before dying... So in reality this will get used with software triggers only unless someone has this long out of production device on a quick board. Signed-off-by:

This patch adds support for MCP454x, MCP456x, MCP464x and MCP466x parts. The main difference with currently supported parts (MCP453x and alike) is the addition of a non-volatile memory in order to recall the wiper setting at power-on. This feature is currently not supported and only the volatile memory is used to set the wiper. Signed-off-by:

The filter frequency and sample rate have a fixed relationship. Only the filter frequency is unique, however. Currently the driver ignores the filter settings for 32 Hz and 64 Hz. This patch adds the necessary callbacks to be able to configure and read the filter setting from sysfs. Signed-off-by:

The calibration data is described as coming from an E2PROM and that means it does not change. Just read it once at probe time and store it in the device state container. Also toss the calibration data into the entropy pool since it is device unique. Reviewed-by:

The PM280 has an internal standby-mode, but to really save power we should shut the sensor down and disconnect the power. With the proper .pm hooks we can enable both runtime and system power management of the sensor. We use the *force callbacks from the system PM hooks. When the sensor comes back we always reconfigure it to make sure it is ready to roll as expected. Cc: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by:

The first version of this sensor, BMP085, supports sending an End-of-Conversion (EOC) interrupt. Add code to support this using a completion, in a similar vein as drivers/misc/bmp085.c does. Make sure to check that we are given a rising edge, because the EOC line goes from low-to-high when the conversion is ready. Signed-off-by:

This patch mimics the SPI functionality found in the misc driver in drivers/misc/bh085-spi.c to make it possible to reuse the existing BMP280/BMP180/BMP085 driver with all clients of the other driver. The adoption is straight-forward since like the other driver, it is a simple matter of using regmap. This driver is also so obviously inspired/copied from the old misc driver in drivers/misc/bmp085.c that I just took the liberty to add in the authors of the other drivers + self in the core driver file. The MISC driver also supports a variant named "BMP181" so include that here to be complete in comparison to the old driver. The bus mapping code for SPI was written by Akinobu Mita. Signed-off-by:

This creates a separate BMP280_I2C Kconfig entry that gets selected by BMP280 for I2C transport. As we currently only support I2C transport there is not much practical change other than getting a separate object file (or module) for the I2C driver part. The old Kconfig symbol BMP280 will still select the stuff we need so that oldconfig and old defconfigs works fine. Tested-by:

This splits the BMP280 driver in three logical parts: the core driver bmp280-core that only operated on a struct device * and a struct regmap *, the regmap driver bmp280-regmap that can be shared between I2C and other transports and the I2C module driver bmp280-i2c. Cleverly bake all functionality into a single object bmp280.o so that we still get the same module binary built for the device in the end, without any fuzz exporting symbols to the left and right.

The BMP085/BMP180/BMP280 is supplied with two power sources: VDDA (analog power) and VDDD (digital power). As these may come from regulators (as on the APQ8060 Dragonboard) we need the driver to attempt to fetch and enable these regulators. We FAIL if we cannot: boards should either define: - Proper regulators if present - Define fixed regulators if power is hardwired to the component - Rely on dummy regulators (will be present on all DT systems and any boardfile system that calls regulator_has_full_constraints().
