你(们)好
我们使用 SDK 10。
我们希望使用 Linux 为 max96724 + max96717 +相机开发驱动程序。 现在、我们需要为 max96724和 cdns_csi2rx0配置设备树。
&main_i2c1 {
// MAX96724 Deserializer
max96724: gmsl-deserializer@27 {
status = "okay";
compatible = "maxim,max96724";
reg = <0x27>;
#address-cells = <1>;
#size-cells = <0>;
enable-gpios = <&main_gpio0 32 GPIO_ACTIVE_HIGH>;
i2c-alias-pool = <0x40 0x41 0x42 0x43>;
i2c-atr {
#address-cells = <1>;
#size-cells = <0>;
};
// Pipe configuration: bind Link A to Pipe 0
pipe@0 {
reg = <0>;
maxim,link-id = <0>; // Link A
// If maxim,phy-id exists in the base DTS, leaving it out here removes it
};
// Channel configuration: Channel 0 input from Pipe 0, output to PHY1 (corresponding to CSI Port B)
channel@0 {
reg = <0>; // Channel index 0
maxim,pipe-id = <0>; // Data comes from Pipe 0
maxim,phy-id = <1>; // Place maxim,phy-id under the Channel node
ports {
#address-cells = <1>;
#size-cells = <0>;
// Output port connected to CSI2RX
port@0 {
reg = <0>;
max96724_channelB_out: endpoint {
remote-endpoint = <&csi2rx0_in_sensor>;
bus-type = <4>; // CSI2 D-PHY
clock-lanes = <0>;
data-lanes = <1 2 3 4>;
};
};
// Input port
port@1 {
reg = <1>;
endpoint { };
};
};
};
};
};
/* CSI Receiver Configuration */
&cdns_csi2rx0 {
status = "okay";
ports {
#address-cells = <1>;
#size-cells = <0>;
csi0_port0: port@0 {
reg = <0>;
status = "okay";
csi2rx0_in_sensor: endpoint {
remote-endpoint = <&max96724_channelB_out>;
bus-type = <4>; /* CSI2 DPHY */
clock-lanes = <0>;
data-lanes = <1 2 3 4>;
};
};
};
};
但根据日志,它似乎失败了。
