[Intel-gfx] [PATCH v6 12/24] drm/i915/dg1: gmbus pin mapping

Add tables to map the GMBUS pin pairs to GPIO registers and port to DDC. >From spec we have registers GPIO_CTL[1-4], so we should not do the 4->9 mapping as in ICL/TGL. The values for VBT seem wrong in BSpec. For the current boards we actually have a 1:1 mapping. BSpec: 49311, 49945, 20124 Cc: A
