Currently, none of the upstream Qualcomm DT files have the display device nodes populated, even when the DT binding documents are upstream.
I am not aware of all the issues with the bindings which has prevented it from getting merged, but 2 properties "connectors" (maintains a list of all the external interfaces (DSI, HDMI etc)) and "gpus" (list of GPU devices) seem like the ones that can't be merged.
This patch set aligns with the graph bindings to describe the connection between the display controller block (MDP) and the external encoder interfaces.
This is similar to the graph bindings used by some of the drivers (imx, rockchip), but not exactly the same. These drivers expect a top level "display-subsytem" DT node which lists down the display interface ports to be used. Our implementation just parses the interface ports in the MDP node as is, and add the components that are needed. I've Cc-ed Heiko and Philipp in case they had any comments on this.
The 'gpu' property is removed in a hack-ish way. The driver contains a list of all the compatible strings for gpus, and searches the entire OF firmware for a matching node. Once we know what's the right way to link the gpu and display nodes together (if needed at all) we can add the required binding.
The rest of the changes are minor cleanups and fixes to prepare the driver and binding documents before we really start adding the display nodes.
