From 8b364b41ced2ac8eea9958ea084f10289a85419b Mon Sep 17 00:00:00 2001 From: Matt Roper Date: Wed, 26 Oct 2016 15:51:28 -0700 Subject: [PATCH] drm/i915: Rename for_each_plane -> for_each_universal_plane This macro's name is a bit misleading; it doesn't actually iterate over all planes since it omits the cursor plane. Its only uses are in gen9 code which is using it to iterate over the universal planes (which we treat as primary+sprites); in these cases the legacy cursor registers are programmed independently if necessary. The macro's iterator value (0 for primary plane, spritenum+1 for each secondary plane) also isn't meaningful outside the gen9 context where the hardware considers them to all be "universal" planes that follow this numbering. This is just a renaming/clarification patch with no functional change. However it will make the subsequent patches more clear.
