Subject: [Intel-gfx] [PATCH v3 11/16] drm/hdcp: Max MST content streams
Date: Thu, 22 Oct 2020 14:25:47 +0530 [thread overview]
Message-ID: <20201022085552.18353-12-anshuman.gupta@intel.com> (raw)
In-Reply-To: <20201022085552.18353-1-anshuman.gupta@intel.com>
Let's define Maximum MST content streams up to four
generically which can be supported by modern display
controllers.
