From fb9248e202df17cf731c76305f6015bf409179ca Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Tue, 11 Jul 2017 23:42:32 +0300 Subject: [PATCH] drm/i915/hsw, bdw: Add an ID for the global display power well Add an ID for the HSW/BDW global display power well for consistency. The ID is selected so that it can be used to get at the HW request and status flags with the corresponding GEN9+ macros. Unifying the HSW/BDW and GEN9+ versions of these macros and the power well ops using them will be done in follow-up patches. v2: - Rebased on v2 of patch 2.
