Subject: [PATCH v4 02/23] drivers/fsi: Add slave definition
Date: Wed, 29 Mar 2017 12:43:19 -0500 [thread overview]
Message-ID: <20170329174340.89109-3-cbostic@linux.vnet.ibm.com> (raw)
In-Reply-To: <20170329174340.89109-1-cbostic@linux.vnet.ibm.com>
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.
