Subject: drm/i915/bdw: Broadwell has a max port clock of 300Mhz on HDMI
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e3c3357863db7cb8e847b3adff5b6be94cecde82;p=linux-beck.git

drm/i915/bdw: Broadwell has a max port clock of 300Mhz on HDMI

Just like HSW.

This means we can scan out a mode with a 300Mhz pixel clock with a depth
of 24 bits, but only a 200Mhz one with a 36bits depth.
