[00/19] drm/i915: Refactor the display power domain mappings

Message

Imre Deak Jan. 28, 2022, 11:48 a.m. UTC

This patchset moves the per-platform display power domain->power well
mapping descriptors to a separate file and simplifies them by sharing
descriptor data among port power well instances and platforms where
possible.

The power well and domain names are also sanitized to match the actual
specification terminology. For this the patchset removes the aliasing
among the display power domain enum values, which in turn required
extending the u64 domain mask to a bitmap.

I also pushed the changes to:
