Subject: [RFC/PATCH 0/1] Quadrature Encoder Support
Date: Mon,  9 Sep 2019 15:16:04 +0300	[thread overview]
Message-ID: <20190909121605.92008-1-felipe.balbi@linux.intel.com> (raw)

Hi,

Here's a simple RFC for Intel's Quadrature Encoder. Let me make it clear
that I don't mean we should the following patch as is, rather I'd like
to open the discussion to, perhaps, extending Industrial Automation
Framework with support for Quadrature Encoders.

Let me know if you think IIO would be correct place for such devices,
then I can start reworking the driver to provide an IIO-compliant
interface.

I'm thinking we would need standard sysfs files for configuring the QEP
into single-shot QEP mode or buffered Capture mode, configure thresholds
and other details.

Cheers
