[Intel-gfx] [PATCH 1/5] drm/i915: Fix DDI port_clock for VGA output

2014-02-27 Thread ville . syrjala
From: Ville Syrjälä On DDI there's no PLL as such to generate the pixel clock for VGA. Instead we derive the pixel clock from the FDI link frequency. So to make .compute_config match what .get_config does, we need to set the port_clock based on the FDI link frequency. Note that we don't even che
