Subject: [PATCH v2 04/18] drivers/fsi: Add slave definition
Date: Thu, 12 Jan 2017 16:25:28 -0600 [thread overview]
Message-ID: <1484259928-79186-1-git-send-email-christopher.lee.bostic@gmail.com> (raw)
From: Jeremy Kerr <jk@ozlabs.org>
Add the initial fsi slave device, which is private to the core code.
This will be a child of the master, and parent to endpoint devices.
