Subject: [PATCH] drm/i915/cnl: Add slice and subslice information to debugfs.
Git-commit: 1dd7a3e7af70ebdd0cdd937b180726d15a4f0948
Patch-mainline: v4.13-rc6
References: FATE#322643 bsc#1055900
No-fix: 7ea1adf30f82a4c0910524ac06f8f1f26281bb23
A missing part to EU slice power gating is the
debugfs interface. This patch actually should have been
squashed to the initial EU slice power gating one.
V2: Initial patch was merged without this part.
Fixes: c7ae7e9ab207 ("drm/i915/cnl: Configure EU slice power gating.")
