Sometimes it's useful to stream samples forever, such as when stress-testing a driver overnight to check for memory leaks or other issues. When the program receives a signal, it will gracefully cleanup, so it is still safe to terminate at any time. Add support for specifying a negative -c option, meaning that we should loop forever. To do so, we need to use a long long (instead of just long) for num_loops so that current code specifying num_loops greater than UNSIGNED_LONG_MAX doesn't break. Signed-off-by:

I announced the intent to drop some of these meter drivers on the IIO list last cycle. This device is obsolete and not easily obtained. No one has come forward with suitable test hardware and the driver would need a lot of work to move out of staging. As such I am dropping it. We can always bring it back again if a user / tester emerges in the future. Signed-off-by: -

A scaling factor of approximately 2 * Pi / (2^12 -1) is added, to scale the 12-bits angular position to radians. A return type of IIO_VAL_INT_PLUS_NANO is used, so that the scale of both the angle channel and angular velocity channel has 7 significant digits. Signed-off-by:

The sysfs iio ABI states radians per second is expected as the unit for angular velocity, but the 12-bit angular velocity register has revolution per seconds as its unit. So a scaling factor of approximately 2 * Pi is added to the angular velocity channel. Signed-off-by:

The AD5681R/AD5682R/AD5683/AD5683R are a family of one channel DACs with 12-bit, 14-bit and 16-bit precision respectively. The devices have either no built-in reference, or built-in 2.5V reference. These devices are similar to AD5691R/AD5692R/AD5693/AD5693R except with a few notable differences: * they use the SPI interface instead of I2C * in the write control register, DB18 and DB17 are used for setting the power mode, while DB16 is the REF bit. This is why a new regmap type was defined and checked accordingly. * the shift register is 24 bits wide, the first four bits are the command bits followed by the data bits. As the data comprises of 20-bit, 18-bit or 16-bit input code, this means that 4 LSB bits are don't care. This is why the data needs to be shifted on the left with four bits. Therefore, AD5683_REGMAP is checked inside a switch case in the ad5686_spi_write() function. On the other hand, similar devices such as AD5693R family, have the 4 MSB command bits followed by 4 don't care bits.

These devices are pretty similar to AD5671R/AD5675R and AD5694/AD5694R/AD5695R/AD5696/AD5696R, except that they have one channel. Another difference is that they use a write control register(addr 0x04) for setting the power down modes and the internal reference instead of separate registers for each function.

The times reported by the in_illuminance_integration_time_available sysfs attribute are actually in milliseconds, not microseconds. This patch corrects the times with the correct unit. The fixes tag is inaccurate as the issue existed when the driver was still in staging. However, lots of changes occured before it graduated so this is as a good a point as any for backports.

Move the tsl2772 driver out of staging and into mainline. Signed-off-by:
-
Brian Masney authored
This patch renames this driver from tsl2x7x to tsl2772 since it is highly likely that additional devices will be added to this driver that do not match that wildcard. The tsl2772 driver name was selected since that is currently the device with the most features that are supported by this driver. This patch also adds Brian Masney's copyright to tsl2772.h for all of the work that has been done to move this driver out of staging. Signed-off-by:

The thresh periods assumed an integration time of 3ms. This patch adds support for the correct integration time (2.72ms or 2.73ms). The code had the ALS filter values as going up to 15, however the values actually went up to 60 since the values scaled in increments of 5 once the persistence value went above 3. Signed-off-by:

Make the sysfs attributes in_proximity0_calibscale_available, and in_intensity0_{calibscale,integration_time}_available be created using info_mask_separate_available on the channel configuration. The driver assumed that the ALS increment was 2.72 ms, and the upper range was 696 ms. Some other supported devices use 2.73 ms - 699 ms. This patch adds support for the multiple ranges.

Prior to this loop, we check if fifo_count < bytes_per_datum and bail if so. This means that when we hit the loop, we know that fifo_count >= bytes_per_datum, so the check is unneeded and we can turn the loop into a do-while for a slight performance improvement. Signed-off-by:
