David, Daniel,
I'll need a word from you regarding this patch. It's needed in patch 22/23 in this series. vop2_crtc_atomic_enable() needs to control the mux which routes the display output to the different encoders. Which encoder is used is described in the of_graph port, so I need a way to identify the encoder in the device tree.

Add a device node to drm_encoder which corresponds with the port node in the DT description of the encoder. This allows drivers to find the of_graph link between a crtc and an encoder.
