From 1705f22c86fb2654df22169c020d9d4ff193e47b Mon Sep 17 00:00:00 2001 From: Matt Roper Date: Thu, 29 Jul 2021 09:59:54 -0700 Subject: [PATCH] drm/i915/dg2: Update steering tables DG2's replicated register ranges are almost the same at XeHP SDV with the exception of one LNCF sub-range that switches to gslice steering. We can re-use the XeHP SDV mslice steering table and just provide a DG2-specific LNCF steering table.
