From 4a4064ad79699ee41b74c12fa4f9f960a5bf9b2d Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Tue, 21 Jul 2020 02:29:52 +0300 Subject: drm/i915/tgl: Make sure TC-cold is blocked before enabling TC AUX power wells MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The dependency between power wells is determined by the ordering of the power well list: when enabling the power wells for a domain, this happens walking the power well list forward, while disabling them happens in the reverse direction. Accordingly a power well on the list must follow any other power well it depends on. Since the TC AUX power wells depend on TC-cold being blocked, move the TC-cold off power well before all AUX power wells.
