From 75e39688f350f63dc916c1b9d01c973a3a7bf5c8 Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Mon, 6 Aug 2018 12:58:39 +0300 Subject: [PATCH] drm/i915/ddi: Use power well CTL IDX instead of ID Similarly to the previous patch use a separate request/status HW flag index defined right after the corresponding control registers instead of depending for this on the power well IDs. Since the set of control/status registers varies among the different power wells (on a single platform), also add a new i915_power_well_registers struct that we populate and assign to each DDI power well as needed. Also clarify a bit the code comment describing the function and layout of the control registers. This also fixes a problem on ICL, where we incorrectly read the KVMR control register in hsw_power_well_requesters() even for DDI and AUX power wells. v2: - Clarify platform range tags in code comments. (Paulo) - Fix line over 80 chars checkpatch warning.
