Subject: [PATCH v3 03/23] PCI: endpoint: Introduce configfs entry for configuring EP functions
Date: Thu, 9 Mar 2017 13:27:14 +0530 [thread overview]
Message-ID: <1489046254-19919-4-git-send-email-kishon@ti.com> (raw)
In-Reply-To: <1489046254-19919-1-git-send-email-kishon@ti.com>
Introduce a new configfs entry to configure the EP function (like
configuring the standard configuration header entries) and to
bind the EP function with EP controller.
