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.

Fix the following sparse warnings: CHECK drivers/iio/adc/stm32-dfsdm-adc.c symbol 'stm32_dfsdm_get_buff_cb' was not declared. Should it be static? symbol 'stm32_dfsdm_release_buff_cb' was not declared. Should it be static? BTW, move interrupt.h to sort headers alphabetically. Signed-off-by:

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 CALIBBIAS and INT_TIME masks in tsl2x7x_write_raw did not have any range checking in place so this patch adds the appropriate range checking. The defines TSL2X7X_ALS_GAIN_TRIM_{MIN,MAX} are also introduced by this patch. Signed-off-by: -
Brian Masney authored
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.

This patch turns the chip off if IIO device registration fails so that the error handling mirrors the device remove to make review easier in preparation for moving this driver out of staging.

Adds the ability to run the Mag3110 in continuous mode to speed up the sampling rate. Depending on the sampling rate requested the device can be put in or out of continuous mode automatically. Shifting out of continuous mode requires a potential 1 / ODR wait which is also implemented. Modified the sleep method when data is not ready to allow for sampling > 50sps to work. Signed-off-by:

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:

The MMAL and V4L2 buffers had been disassociated, and linked on demand. Seeing as both are finite and low in number, and we now have the same number of each, link them for the duration. This removes the complexity of maintaining lists as the struct mmal_buffer context comes back from the VPU, so we can directly link back to the relevant V4L2 buffer. Signed-off-by:
