As part of the general cleanup of indio_dev->mlock, this change replaces it with a local lock. The lock protect the state of the device from potential concurrent writes. The device is configured via a sequence of SPI writes, and this lock is meant to prevent the start of another sequence before another one has finished. This is part of a bigger cleanup.

As part of the general cleanup of indio_dev->mlock, this change replaces it with a local lock on the device's state from potential concurrent write accesses from userspace. The write operation requires an SPI write, then toggling of a GPIO, so the lock aims to protect the sanity of the entire sequence of operation. This is part of a bigger cleanup.

As part of the general cleanup of indio_dev->mlock, this change replaces it with a local lock. The lock protects against potential races when reading the CR reg and then updating, so that the state of pm_runtime is consistent between the two operations. This is part of a bigger cleanup.

Provide a way for continuous data capture by setting up buffer support. The data ready signal exposed at the SYNC pin of the ADXRS290 is exploited as a hardware interrupt which triggers to fill the buffer. Triggered buffer setup was tested with both hardware trigger (DATA_RDY) and software triggers (sysfs-trig & hrtimer). Signed-off-by:

We found some sensors which are much slower (20% at room temperature) than nominal. According to the data sheet, up to 27% is possible. Now I add 33% to the nominal time out, hopefully this is enough. Signed-off-by:

Since object temperature might be different than the sensor temperature the infrared sensors should provide an interface to inject ambient temperature. This was in past done via write to ambient temperature interface (in_temp_ambient_raw), but I think most people did not know about it. This solution introduces a new iio type of the CALIBAMBIENT which is hopefully more descriptive and more explicit about the purpose and capabilities of the sensors. Signed-off-by:

On one board I found that: probe of 5-0028 returned 1 after 259547 usecs While some of this time is attributable to the pile of i2c transfers that we do at probe time, the lion's share (over 200 ms) is sitting waiting in the polling loop in sx9310_init_compensation() waiting for the hardware to indicate that it's done. There's no reason to block probe of all other devices on our probe. Turn on async probe. Signed-off-by:

The driver is quite likely used only on ACPI based platforms and rarely build with CONFIG_ACPI=n. Even though, the few dozens of bytes is better than ugly ifdeffery and inclusion of heavy header. As a result, replace acpi.h with mod_devicetable.h. Signed-off-by:

A transfer may fall shorter than the bytes in the block. This information is available in the residue from the DMA engine, so we can compute actual `bytes_used` with that by subtracting the residue. Signed-off-by:

Simple binding so easy to convert. Dropped the stated value of maximum spi bus frequency as it does not seem to correspond to the datasheet. The value of 200kHz is the max sampling frequency of the ADC, not the clock frequency of the SPI bus. Added #io-channel-cells to allow use as a provider of channels to other devices via the consumer binding. Signed-off-by:

By default, if all three channels (x, y, z) are enabled, sample sets of concurrent 3-axis data is stored in the FIFO. This patch adds the option to configure the FIFO to store peak acceleration (x, y and z) of every over-threshold event. When pushing to iio buffer we push only enabled axis data. Currently the driver configures adxl372 to work in loop mode. The inactivity and activity timings decide how fast the chip will loop through the awake and waiting states and the thresholds on x,y,z axis decide when activity or inactivity will be detected. This patch adds standard events sysfs entries for the inactivity and activity timings: thresh_falling_period/thresh_rising_period and for the in_accel_x_thresh_falling/rising_value. Signed-off-by:

For some time the market wants medical grade accuracy in medical range, while still retaining the declared accuracy outside of the medical range within the same sensor. That is why we created extended calibration which is automatically switched to when object temperature is too high. This patch also introduces the object_ambient_temperature variable which is needed for more accurate calculation of the object infra-red footprint as sensor's ambient temperature might be totally different than what the ambient temperature is at object and that is why we can have some more errors which can be eliminated. Currently this temperature is fixed at 25, but the interface to adjust it by user (with external sensor or just IR measurement of the other object which acts as ambient), will be introduced in another commit.
