FXOS8700CQ is a small, low-power, 3-axis linear accelerometer and 3-axis magnetometer combined into a single package. The device features a selectable I2C or point-to-point SPI serial interface with 14-bit accelerometer and 16-bit magnetometer ADC resolution along with smart-embedded functions. FXOS8700CQ has dynamically selectable accelerationfull-scale ranges of ±2 g/±4 g/±8 g and a fixed magnetic measurement range of ±1200 μT. Output data rates (ODR) from 1.563 Hz to 800 Hz are selectable by the user for each sensor. Interleaved magnetic and acceleration data is available at ODR rates of up to 400 Hz. FXOS8700CQ is available in a plastic QFN package and it is guaranteed to operate over the extended temperature range of –40 °C to +85 °C.

The count_read and count_write callbacks are simplified to pass val as unsigned long rather than as an opaque data structure. The opaque counter_count_read_value and counter_count_write_value structures, counter_count_value_type enum, and relevant counter_count_read_value_set and counter_count_write_value_get functions, are removed as they are no longer used.

The AB8500 GPADC driver is indeed a "general purpose ADC" driver, and while the IIO subsystem did not exist when the driver was first merged, it is never too late to clean things up and move it to the right place. Nowadays IIO provides the right abstractions and interfaces to do generic ADC work in the kernel. We have to cut a bunch of debugfs luggage to make this transition swift, but all these files to is read out the raw values of the ADC and the IIO subsystem already has a standard sysfs ABI for doing exactly this: no debugfs is needed.

This is a new driver for the ST-Ericsson AB8500 GPADC, which replaces the old driver in drivers/mfd/ab8500-gpadc.c and thus gets rid of another necessarily different custom driver from the times before IIO existed. The AB8500 GPADC can convert 10 different channels and these are used for monitoring voltages in the U8500 chipset, some are used for battery charging, some for temperature monitoring. As this is very core functionality that a lot of drivers depend on and was formerly compiled in with the AB8500 core driver, we deafault it to 'y' in Kconfig: it can be compiled out but it is really not advisible: the platform can for example overheat if we do.

Immutable branch being merged in. Created as this also involves moving some dependencies around, outside of the counter subsystem. It's possible it will want to be pulled into other trees.

This adds a new counter driver for the Texas Instruments Enhanced Quadrature Encoder Pulse (eQEP) module. Only very basic functionality is currently implemented - only enough to be able to read the position. The actual device has many more features which can be added to the driver on an as-needed basis. It is not possible to read the QEPA/B signal values in hardware, so that feature is omitted. The TI_PWMSS kernel option is selected in Kconfig to enable the parent bus, which is needed for power management. Signed-off-by:

The TI PWMSS driver is a simple bus driver for providing power power management for the PWM peripherals on TI AM33xx SoCs, namely eCAP, eHRPWM and eQEP. The eQEP is a counter rather than a PWM, so it does not make sense to have the bus driver in the PWM subsystem since the PWMSS is not exclusive to PWM devices. Signed-off-by:

This change replaces indio_dev's mlock with the driver's own lock. The lock is mostly needed to protect state when changing the `dac_cache` info. The lock has been extended to `ad7303_read_raw()`, to make sure that the cache is updated if an SPI-write is already in progress. Signed-off-by:

On LSM6DSO/LSM6DSR/LSM6DSOX/ASM330LHH and ISH330DHCX devices it is possible to trim the hardware timestamp resolution through the FREQ_FINE[7:0] bits of the INTERNAL_FREQ_FINE register, which contains the difference in percentage of the effective ODR (and timestamp rate) with respect to the typical value. The formula for calculating the effective ODR reported in the application notes has been linearized to the first order to simplify the calculation (pls. see note on source code). This change may be useful in the outcome of CTS tests regarding the SingleSensorTests and the SensorTest#testSensorTimeStamps for high ODRs Signed-off-by:
