From d9fcdc8d1f8e7b12111bb410abc4c27c411aa5d9 Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Mon, 6 Aug 2018 12:58:42 +0300 Subject: [PATCH] drm/i915: Use existing power well IDs where possible There is no need for separate IDs for power wells on a new platform with the same functionality as an other power well on a previous platform, we can just reuse the ID from the previous platform. This is only possible after the previous patches where we removed dependence on the actual enum values. This also fixes a problem on ICL where in assert_can_enable_dc5/9() we would've failed to look up the PW#2 power well. v2: - Keep an ID assigned for the ICL PW#2 power well too.
