Ville Syrjälä 7f1052a8fa drm/i915: Update CDCLK_FREQ register on BDW after changing cdclk frequency ... Update CDCLK_FREQ on BDW after changing the cdclk frequency. Not sure if this is a late addition to the spec, or if I simply overlooked this step when writing the original code. This is what Bspec has to say about CDCLK_FREQ: "Program this field to the CD clock frequency minus one. This is used to generate a divided down clock for miscellaneous timers in display." And the "Broadwell Sequences for Changing CD Clock Frequency" section clarifies this further: "For CD clock 337.5 MHz, program 337 decimal. For CD clock 450 MHz, program 449 decimal. For CD clock 540 MHz, program 539 decimal. For CD clock 675 MHz, program 674 decimal."
