--- Comment #29 from Anssi Hannula anssi@mageia.org ---
Use the driver calculated CTS and N values rather than having hardware generate them. This allows us to use the modeline pixel clock rather than the actual pll clock when setting up the dto for audio. Fixes problems with audio playback rate on certain asics if the pll clock does not match the pixel clock exactly.
Hm, so actual problems were confirmed fixed with this? That seems rather strange, since that would mean the hardware counted the clock cycles wrong for the CTS value... Maybe the HW doesn't do it per-spec, instead calculating CTS in some other way?
