Subject: [PATCH 2/2] regmap: use debugfs even when no device
Date: Tue, 23 Jan 2018 16:53:43 -0600 [thread overview]
Message-ID: <1516748023-17235-3-git-send-email-david@lechnology.com> (raw)
In-Reply-To: <1516748023-17235-1-git-send-email-david@lechnology.com>
This registers regmaps with debugfs even when they do not have an
associated device. For example, this is common for syscon regmaps.
