[PATCH v2 17/41] drm/connector: Add pixel clock to cmdline mode

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
