Document that the hardware supports falling edge, rising edge, level low, and level high interrupt types, rather than just rising edge. The language used is the same as that in st_lsm6dsx.txt. Signed-off-by:

Currently, we support only rising edge interrupts, and in fact we assume that the interrupt we're given is rising edge (and things won't work if it's not). However, the device supports rising edge, falling edge, level low, and level high interrupts. Empirically, on my system, switching to level interrupts has fixed a problem I had with significant (~40%) interrupt loss with edge interrupts. This issue is likely related to the SoC I'm using (Allwinner H3), but being able to switch the interrupt type is still a very useful workaround. I tested this with each interrupt type and verified correct behavior in a logic analyzer. Add support for these interrupt types while also eliminating the error case of the device tree and driver using different interrupt types. Signed-off-by:

Rewrite set_power_itg. Failing when turning power off is no more decreasing the counter now and sleeping only happens when effectively turning the chip on. Fix also usage in init function (setting power on one time is sufficient to ensure chip is effectively on). Signed-off-by:

Use 'devm_iio_kfifo_allocate()' instead of 'iio_kfifo_allocate()' in order to simplify code and avoid a memory leak in an error path in 'sca3000_probe()'. A call to 'sca3000_unconfigure_ring()' was missing. Sent via the next merge window as unimportant bug and there are other patches dependent on it. Signed-off-by:

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 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:
