Subject: [PATCH 5/6] drm/i915/power: Convert "i830 power well" code to intel_display
Date: Fri, 6 Sep 2024 17:33:05 +0300 [thread overview]
Message-ID: <20240906143306.15937-6-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20240906143306.15937-1-ville.syrjala@linux.intel.com>
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
struct intel_display will replace struct drm_i915_private as
the main thing for display code. Convert the "i830 power well"
code to use it (as much as possible at this stage).
