From 1b30dbde8596ca8de2497c2a50d5381dfe62ee8c Mon Sep 17 00:00:00 2001 From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Date: Tue, 9 Dec 2014 00:24:49 +0200 Subject: drm: rcar-du: Add support for external pixel clock The DU uses the module functional clock as the default pixel clock, but supports using an externally supplied pixel clock instead. Support this by adding the external pixel clock to the DT bindings, and selecting the clock automatically at runtime based on the requested mode pixel frequency. The input clock pins to DU channels routing is configurable, but currently hardcoded to connect input clock i to channel i.
