- supplay timestamp when sample data is added to the buffer
- do trigger pooling in top half instead threaded IRQ
- refactor external/internal voltage reference logic
- make everything device managed by using devm_add_action_or_reset
- make data rate runtime controllable insted DT parameter
- use generic ADC channel binding for DT channel configuration
- replace global PGA gain with PGA gain per channel
- add support for channel input selection(muliplexer)
- don't use validate_device in iio_trigger_ops struct
- drop the unneceseary return ret;
- minor changes on defines
