Subject: [RFC 1/3] drm/i915/alpm: Move alpm parameters from intel_psr
Date: Mon,  4 Mar 2024 13:13:01 +0530	[thread overview]
Message-ID: <20240304074303.202882-2-animesh.manna@intel.com> (raw)
In-Reply-To: <20240304074303.202882-1-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.
