[PATCH v2 03/19] drm/i915: Move the i915_power_well_regs struct into i915_power_well_ops

Imre Deak imre.deak at intel.com
Fri Jan 28 01:08:33 UTC 2022


Move the i915_power_well_regs struct into i915_power_well_ops. Most of
the power wells use the same ops/regs combination, so this saves some
space and also simplifies the platform power domain->power well
definitions.
