Interrupts were added by commit ffe0ab6a9698 ("iio: accel: bma400: Add triggered buffer support"). Support for events was added by commit 961db2da159d ("iio: accel: bma400: Add support for single and double tap events"), among others. The driver now has an interrupt handler pushing IIO events, and event configuration from read_event_config(), write_event_config(), read_event_value(), and write_event_value(). A step count channel was also added by commit d221de60eee3 ("iio: accel: bma400: Add separate channel for step counter"). The power management and sensor time channel TODOs remain unimplemented. Signed-off-by: Marco Chen --- I would like to take on the remaining power management TODO. The driver has bma400_set_power_mode() but neither bus assigns a dev_pm_ops struct. POWER_MODE_LOW is also never entered. I don't have a BMA400 but I would definitely buy one to develop and test on. I also have access to a logic analyzer for testing. Is this a patch that is desirable? drivers/iio/accel/bma400_core.c | 2 -- 1 file changed, 2 deletions(-) diff --git a/drivers/iio/accel/bma400_core.c b/drivers/iio/accel/bma400_core.c index 7e3cff4cca91..6bc64ca87f4b 100644 --- a/drivers/iio/accel/bma400_core.c +++ b/drivers/iio/accel/bma400_core.c @@ -6,8 +6,6 @@ * * TODO: * - Support for power management - * - Support events and interrupts - * - Create channel for step count * - Create channel for sensor time */ -- 2.55.0
