Subject: [PATCH v2 1/6] drm/i915/alpm: Move alpm parameters from intel_psr
Date: Fri, 12 Apr 2024 21:22:38 +0530	[thread overview]
Message-ID: <20240412155243.2891996-2-animesh.manna@intel.com> (raw)
In-Reply-To: <20240412155243.2891996-1-animesh.manna@intel.com>

ALPM can be enabled for non psr panel and currenly aplm-params are
encapsulated under intel_psr struct, so moving out to intel_dp struct.
