cool, with v2 of patch 1 v2 of patch 2 patch 3 display works properly here on cnl. On Mon, Jul 10, 2017 at 6:02 AM, wrote: > From: Ville Syrjälä > > Follow the GLK path when computing cdclk and related limits. CNL > pipes also produce two pixels per clock, so that's what we should > really us

From: Ville Syrjälä Follow the GLK path when computing cdclk and related limits. CNL pipes also produce two pixels per clock, so that's what we should really use. However for the purposes of pixel rate calculations we will assume one pixel per clock to keep the voltage higher, at least until the
