[PATCH 3/3] drm/i915: Use the ddi_ports info to kill ugly CNL_WITH_PORT_F.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Now that we have the number of ddi ports information available
let's use it instead of that ugly platform macro.

v2: - Don't override platform info (Jani) But use platform info (Daniel)
    - Don't use ddi_ports when it doesn't make sense (Lucas)
    - Add a comment to let clear that port E is fused off. (Rodrigo)
