Subject: [PATCH v3 05/18] drivers/fsi: Add slave definition
Date: Wed, 1 Feb 2017 10:53:45 -0600 [thread overview]
Message-ID: <20170201165358.45415-6-cbostic@linux.vnet.ibm.com> (raw)
In-Reply-To: <20170201165358.45415-1-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.
