Subject: [PATCH v10 1/2] dt-bindings: drm/bridge: anx7625: MIPI to DP transmitter binding
Date: Wed, 6 May 2020 15:04:20 +0800 [thread overview]
Message-ID: <b720f7d2c5338813d31b7f715f59ca68c367d5a8.1588747998.git.xji@analogixsemi.com> (raw)
In-Reply-To: <cover.1588747998.git.xji@analogixsemi.com>
The ANX7625 is an ultra-low power 4K Mobile HD Transmitter designed
for portable device. It converts MIPI to DisplayPort 1.3 4K.
You can add support to your board with binding.
Example:
anx7625_bridge: encoder@58 {
compatible = "analogix,anx7625";
reg = <0x58>;
status = "okay";
enable-gpios = <&pio 45 GPIO_ACTIVE_HIGH>;
reset-gpios = <&pio 73 GPIO_ACTIVE_HIGH>;
ports {
#address-cells = <1>;
#size-cells = <0>;
mipi2dp_bridge_in: port@0 {
reg = <0>;
anx7625_in: endpoint {
remote-endpoint = <&mipi_dsi>;
};
};
mipi2dp_bridge_out: port@1 {
reg = <1>;
anx7625_out: endpoint {
remote-endpoint = <&panel_in>;
};
};
};
};
