Subject: [PATCH 2/2] iio: Documentation: Add ina2xx shunt_resistor attribute documentation
Date: Mon, 17 Jul 2017 01:34:10 +0200 [thread overview]
Message-ID: <2351a045a0564f5bb2af6c652d1fa5e3@rwthex-w2-b.rwth-ad.de> (raw)
In-Reply-To: <20170716233410.22880-1-stefan.bruens@rwth-aachen.de>
The ina2xx driver appeared in the Linux kernel version 4.5, but provided
no documentation. Contrary to other uses of resistance in IIO, ina2xx uses
microohms instead of ohms in the sysfs attribute.
