Hello, The first patch adds support for configuring the Sampling frequency (inter-measurement period) of the sensor. The values should be provided in milihertz. The default value for the inter-measurement period for ALS is 10ms or 100000 mHz and for Range is 50ms or 20000 mHz. The second patch adds support for interrupt based single shot reading. We registered an irq_handler that fires everytime the data is ready. And then we read the appropriate value in the `vl6180_measure` routine. The third patch adds support for continuous mode in the sensor by using buffers. We enable the sensor's continuous mode in the buffer_postenable function depending on the `active_scan_mask`. The continuous mode can be disabled by disabling the buffer. Added a trigger to the device for the continuous mode. Also validating that the device uses the internal trigger provided by us. Changes in v2: - Fixed `label followed by a declaration is a C23 extension [-Wc23-extensions]` by moving the guard(mutex)(&data->lock) above the switch statement. - The above error was pointed out during testing by kernel-test-robot Changes in v3: - Fixed race condition related to `reinit_completion` - Used `iio_for_each_active_channel` instead of manually accessing `masklength` - Accepting sampling frequency values in milihertz instead of miliseconds. - Minor code refactoring.
