From 0e308efe232afdec35d508f5dfae52f03d50efca Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Mon, 14 Nov 2022 14:00:31 +0100 Subject: [PATCH] drm/connector: Add pixel clock to cmdline mode MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit We'll need to get the pixel clock to generate proper display modes for all the current named modes. Let's add it to struct drm_cmdline_mode and fill it when parsing the named mode.
