| Subject: drm/i915: Fix TV Out refresh rate. |
| |
| From: Rodrigo Vivi <rodrigo.vivi@gmail.com> |
| |
| commit 23bd15ec662344dc10e9918fdd0dbc58bc71526d upstream. |
| |
| TV Out refresh rate was half of the specification for almost all modes. |
| Due to this reason pixel clock was so low for some modes causing flickering screen. |
