[PATCH 04/12] drm/mgag200: Split PLL setup into compute and update functions

2021-07-05 Thread Thomas Zimmermann
The _set_plls() functions compute a pixel clock's PLL values and program the hardware accordingly. This happens during atomic commits. For atomic modesetting, it's better to separate computation and programming from each other. This will allow to compute the PLL value during atomic checks and catc
