Subject: [PATCH 0/3] drm/msm: Use device graph to parse connected panels
Date: Mon, 22 Jun 2015 20:24:18 +0530 [thread overview]
Message-ID: <1434984861-22948-1-git-send-email-architt@codeaurora.org> (raw)
drm/msm currently relies on phandles/child nodes to get data about
connected panels to LVDS and DSI. This method has known limitations.
Use device graphs in DT to represent the connections between the encoder
outputs and the panels. Use of_graph helpers in the driver to get the
panel device node.
The usage of device graphs should also simplify management in dual dsi
mode. I haven't tried this out yet, though.
Archit Taneja (3):
drm/msm: dsi host: add missing of_node_put()
drm/msm: dsi host: Use device graph parsing to parse connected panel
drm/msm: mdp4 lvds: get panel node via of graph parsing
