This series adds some additional features to the mma8452 accelerometer driver * debugfs register access * transient threshold events * highpass filter * interrupt driven sampling (trigger) Attributes are added to the core for: * highpass filter for readings * both high and lowpass filters for events In addition a latent bug in the device initialisation is fixed. V5 changes: * Moved event highpass filter event attribute declaration from patch 4 to 6 (to be with the implementation code) * Added a validate_device function to prevent use of trigger with other devices The first three patches have already been applied to -next but have been resent, unchanged, in this series to keep it all together. -- To unsubscribe from this list: send the line "unsubscribe linux-iio" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
