Content-Type: text/plain; charset=ISO-8859-1 Sender: linux-iio-owner@vger.kernel.org List-Id: linux-iio@vger.kernel.org Hi All, I vaguely recall asking this in response to certain drivers over the years, but what is the usecase for userspace 'resetting' a device via a reset attribute? It's reasonably common in the drivers but not (as I've kept it out) in the abi docs. It is common in some of Analog's inertial sensor drivers but I think turns up in various other places. Jonathan
