iio: dac: ad5446: Add support for new AD5600 DAC

2019-11-10T15:14:06Z

The AD5600 is a single channel, 16-bit resolution, voltage output digital to analog converter (DAC). The AD5600 uses a 3-wire SPI interface. It is part of the AD5541 family of DACs. The ad5446 IIO driver implements support for some of these DACs (in the AD5441 family), so the change is a simple entry in this driver.

iio: dac: ad7303: replace mlock with own lock

2019-10-15T20:11:07Z

This change replaces indio_dev's mlock with the driver's own lock. The lock is mostly needed to protect state when changing the `dac_cache` info. The lock has been extended to `ad7303_read_raw()`, to make sure that the cache is updated if an SPI-write is already in progress. Signed-off-by: Alexandru Ardelean Signed-off-by: Jonathan Cameron

iio: dac: stm32: add power management support

2019-10-15T20:11:06Z

Add support for runtime PM & sleep. Provide pclk to regmap as registers access doesn't need full power (e.g. regulator). Always restore HFSEL when resuming. It may get lost depending on low power level that has been achieved. Signed-off-by: Fabrice Gasnier Signed-off-by: Jonathan Cameron

iio: dac: ad5380: fix incorrect assignment to val

2019-09-03T17:55:50Z

Currently the pointer val is being incorrectly incremented instead of the value pointed to by val. Fix this by adding in the missing * indirection operator.
