2015-12-13ARM: dts: Use OF graph for DP to panel connection in exynos5800-peach-piJavier Martinez Canillas1-1/+14
The DT binding for the Exynos DRM Display Port (DP) driver isn't consistent since it uses a phandle to describe the connection between the DP port and the display panel but uses the OF graph ports and endpoints to describe the connection betwen the DP port, a bridge chip and the panel. The Exynos DP driver and the DT binding have been changed to allow also to describe the DP port to panel connection using ports / endpoints (OF graph) so this patch changes the Exynos5800 Peach Pi DT to make it consistent with the Exynos5420 Peach Pit that has a eDP to LVDS chip and uses OF graph too.

2015-12-13dt-bindings: exynos-dp: update ports node binding for panelInki Dae1-4/+37
This patch updates a ports node binding for panel. With this, dp node can have a ports node which describes a remote endpoint node that can be connected to panel or bridge node. Changelog v2: - remove unnecessary properties and numbering. - update description about eDP device.

2015-12-13drm/exynos: dp: add of_graph dt binding support for panelInki Dae1-1/+20
This patch adds of_graph dt binding support for panel device and also keeps the backward compatibility. i.e., The dts file for Exynos5800 based peach pi board has a panel property so we need to keep the backward compatibility. Changelog v3: - bind only one of two nodes outbound - panel or bridge. Changelog v2: - return -EINVAL if getting a port node failed.
