Subject: [libgpiod][PATCH v3 04/14] bindings: cxx: tests: add tests for bias flags
Date: Mon, 25 Nov 2019 22:31:47 +0800
Message-ID: <20191125143157.26154-5-warthog618@gmail.com> (raw)
In-Reply-To: <20191125143157.26154-1-warthog618@gmail.com>

Extend test coverage over the bias flags in requests and the bias setting
returned by line.bias().
