Hi Kieran, Thank you for the patch. On Thursday, 15 February 2018 10:38:22 EET Kieran Bingham wrote:
From: Kieran Bingham <kieran.bingham@ideasonboard.com> Provide a device node for the ADV7511 as found on the Draak D3 platform. The ADV7511 is connected to the DU through a parallel mux chip, and is configurable in hardware whether it is connected to LVDS0 or LVDS1. Connect through to LVDS0 as a default implementation.
You need to model the LVDS decoder in DT too. I know that no driver and no DT bindings are available at the moment, and I'm aware that this patch enables the HDMI output on the Draak board, but I don't think it's upstreamable as-is.
