Please add something like:
Optional. Should be set if the number
of sample times is larger than one.

Please add something like:
Mandatory if num_sample_times is larger than 1.
If set, number of entries must match
num_sample_times.
> + * @sample_set_masks: All the set_masks for the possible sample times.
Please add something like:
Mandatory if num_sample_times is larger than 1.
If set, number of entries must match
num_sample_times.
> + * @sample_clr_mask: Clear mask to set the default sample time.
Please add something like:
* @resolutions: List of resolutions associated with sample
times.
Optional. Should be set if num_sample_times is
larger than 1, and if the resolution changes
with sample times. If set, number of entries
must match num_sample_times.
