Subject: [Intel-gfx] [v9 10/12] drm/i915/lspcon: Create separate infoframe_enabled helper
Date: Tue,  3 Nov 2020 20:58:32 +0530	[thread overview]
Message-ID: <20201103152834.12727-11-uma.shankar@intel.com> (raw)
In-Reply-To: <20201103152834.12727-1-uma.shankar@intel.com>

Lspcon has Infoframes as well as DIP for HDR metadata(DRM Infoframe).
Create a separate mechanism for lspcon compared to HDMI in order to
address the same and ensure future scalability.
