The AD5694/AD5694R/AD5695R/AD5696/AD5696R are a family of 4 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. The AD5671R/AD5675R are similar, except that they have 8 instead of 4 channels. These devices are similar to AD5672R/AD5676/AD5676R and AD5684/AD5684R/AD5684/AD5685R/AD5686/AD5686R, except that they use i2c instead of spi.

In this patch restructures the existing ad5686 driver by adding a module for SPI and a header file, while the baseline module deals with the chip-logic. This is a necessary step, as this driver should support in the future similar devices which differ only in the type of interface used (I2C instead of SPI). Signed-off-by:

This driver acctually supports the AD5685R device and NOT the AD5685, which does not exist. Maintain old id entry in case we have devicetrees out there which are using the wrong name.

This patch adds a new num_channels attribute as part of the ad5686_chip_info struct which replaces the AD5686_DAC_CHANNELS define. This is a necessary step, since this driver should support similar devices which differ only in the number of channels. Signed-off-by:

Added support for the mpu9255 IMU to the mpu6050 driver. The register map is the same as the other chips; the only driver difference is the compatible string and the WHOAMI register value. Signed-off-by:

There is no need to flush fifo and loose all data when the iio buffer is full. Just drop the data by ignoring the error as commonly done in other drivers. Signed-off-by:

According to the latest datasheet, LSM6DSM and LSM6DSL imu sensors export GENMASK(10, 0) for FIFO threshold mask definition. Despite that is not an actual issue since write on fifo_th register is protected by max_fifo_size value, fix fifo_th and fifo_diff register definitions Fixes: 290a6ce1 ("iio: imu: add support to lsm6dsx driver") Signed-off-by:

The events IIO_EV_INFO_VALUE and IIO_EV_INFO_ENABLE currently have a falling and rising direction configured. There does not need to be a separate distinction so this patch changes these to use the either direction.

The hardware supports 16-bit ALS and proximity readings, however the datasheet recommends using the I2C auto increment protocol so that the correct high and low bytes are read even if the integration cycle ends between reading the lower and upper registers. Signed-off-by:
