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.

2018-05-20iio:dac:ad5686: Add AD5681R/AD5682R/AD5683/AD5683R supportStefan Popa3-8/+74
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.

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.

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.

For historical reasons, the number of buffers passed to the VPU over MMAL did not match that passed from V4L2. That is a silly situation as the driver has to duplicate serialisation and other functions that have already been implemented in V4L2/videobuf2. As we had more V4L2 buffers than MMAL ones, the MMAL buffer headers were returned to the VPU immediately on being filled, which is now invalid. Match the number of buffers notified in queue_setup with that used in MMAL. Return buffers only when we get them from V4L2.
