Subject: [PATCH 1/6] dt-bindings: display: add Amlogic MIPI DSI Host Controller bindings
Date: Fri, 7 Jan 2022 15:55:10 +0100 [thread overview]
Message-ID: <20220107145515.613009-2-narmstrong@baylibre.com> (raw)
In-Reply-To: <20220107145515.613009-1-narmstrong@baylibre.com>
The Amlogic G12A, G12B & SM1 SoCs embeds a Synopsys DW-MIPI-DSI transceiver (ver 1.21a),
with a custom glue managing the IP resets, clock and data input similar to the DW-HDMI Glue
on the same Amlogic SoCs.
