【问题描述】:
我正在使用 yocto rocko / Linux 4.14.24 开发 IMX6QP,并且我正在尝试使用 ADV7513。 我的 CPU 板是karo TX6QP。
尽我所能: DISP0_output (IPU1) -> adv7513_in -> hdmi 连接器
内核配置:
CONFIG_DRM = y
CONFIG_DRM_I2C_ADV7511 = m
dtb: 在 I2C 部分:
hdmi@39 {
compatible = "adi,adv7513";
reg = <0x39>;
interrupt-parent = <&gpio4>;
interrupts = <11 IRQ_TYPE_LEVEL_LOW>;
pd-gpio = <&gpio3 18 GPIO_ACTIVE_HIGH>;
adi,input-depth = <8>;
adi,input-colorspace = "rgb";
adi,input-clock = "1x";
adi,input-style = <1>;
adi,input-justification = "evenly";
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 { /* DISP out */
reg = <0>;
adv7513_in: endpoint {
remote-endpoint = <&ipu1_di0_disp0>;
};
};
port@1 { /* HDMI out */
reg = <1>;
adv7513_out: endpoint {
remote-endpoint = <&hdmi_con>;
};
};
};
};
在主要部分:
hdmi-out0 {
status = "okay";
compatible = "hdmi-connector";
type = "a";
port {
hdmi_con: endpoint {
remote-endpoint = <&adv7513_out>;
};
};
};
ADV7513 未启动,因为它未绑定:从未调用函数“adv7511_bridge_attach”。
如何在 DISP 输出上绑定编码器?
有什么想法吗?
