As discussed previously on the group under the
"Controlling device power management from terminal" thread the mlx90632
sensor provides measurement capabilities under sleep_step mode. This
series runtime suspends the unused chip to sleep step mode to save power
but in case of continuous sequential reading it switches to continuous
mode for faster readouts. This value is hardcoded to
MLX90632_MEAS_MAX_TIME (with some buffer) and not user configurable.
The sensor runtime suspension is set to MLX90632_SLEEP_DELAY_MS which is
hardcoded to 3 times as much as MEAS_MAX_TIME.
Changes in v2:
- apply review comments from Andy Shevchenko
Crt Mori (3):
iio: temperature: mlx90632 Add runtime powermanagement modes
iio: temperature: mlx90632 Read sampling frequency
iio: temperature: mlx90632 Change return value of sensor measurement
