Subject: [PATCH v4 13/16] platform/x86: intel_cht_int33fe: Provide software nodes for the devices
Date: Wed, 22 May 2019 13:51:10 +0300 [thread overview]
Message-ID: <20190522105113.11153-14-heikki.krogerus@linux.intel.com> (raw)
In-Reply-To: <20190522105113.11153-1-heikki.krogerus@linux.intel.com>
Software nodes provide two features that we will need later.
1) Software nodes can have references to other software nodes.
2) Software nodes can exist before a device entry is created.
