Subject: [PATCH 01/24] drm/bridge: allow optionally specifying an .owner device
Date: Fri, 27 Apr 2018 00:31:16 +0200 [thread overview]
Message-ID: <20180426223139.16740-2-peda@axentia.se> (raw)
In-Reply-To: <20180426223139.16740-1-peda@axentia.se>
Bridge drivers can now (temporarily, in a transition phase) select if
they want to provide a full owner or keep just providing an of_node.
By providing a full owner device, the bridge drivers no longer need
to provide an of_node since that node is available via the owner
device.
When all bridge drivers provide an owner device, that will become
mandatory and the .of_node member will be removed.
