Ok, is it good idea to add the flag to struct mma_chip_info like below?

* @mma_scales: scale factors for converting
register values
* to m/s^2; 3 modes: 2g, 4g, 8g; 2 integers
* per mode: m/s^2 and micro m/s^2
+ * @transient_supported: flag indicating whether chip support
transient
+ * event, as not all chips support
transient event
*/
struct mma_chip_info {
u8 chip_id;
const struct iio_chan_spec *channels;
int num_channels;
const int mma_scales[3][2];
+ bool transient_supported;
};

ok sure.

Thanks,
