Subject: [RFC PATCH 12/17] dt-bindings: display: bridge: samsung,mipi-dsim: Add i.MX8MM support
Date: Sun,  4 Jul 2021 14:32:25 +0530	[thread overview]
Message-ID: <20210704090230.26489-13-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20210704090230.26489-1-jagan@amarulasolutions.com>

Samsung MIPI DSIM bridge can also be found in i.MX8MM SoC.

Add dt-bingings for it.
