[RFC PATCH 0/3] allow better control for flushing the hardware fifo

From: Octavian Purdila
Date: Wed Apr 29 2015 - 07:20:01 EST

Hi Jonathan,

The first patch is a small enhancement that makes it easier to add
hwfifo support in drivers.

The other two are adding new ABIs to allow on demand trigger of a
hardware fifo flush operation and to signal when the flush operation
has been completed. The user for this interface is Android's sensor


Octavian Purdila (3):
iio: add hwfifo attributes helpers
iio: allow better control for flushing the hardware fifo
iio: accel: bmc150: add support for hwfifo_flush and flush events
