adv7513 on imx6

Question asked by beal romain on Oct 23, 2018

Hi,

I am working on IMX6QP with yocto rocko / Linux 4.14.24 and I am trying to use the ADV7513.

 

On my hard :

DISP0_output (IPU1) -> adv7513_in -> hdmi connector

 

Kernel

CONFIG_DRM = y

CONFIG_DRM_I2C_ADV7511 = m

 

dtb

In I2C section :

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>;
};
};
};
};

 

In main section : 

hdmi-out0 {

status = "okay";
compatible = "hdmi-connector";
type = "a";

port {
hdmi_con: endpoint {
remote-endpoint = <&adv7513_out>;
};
};
};

 

The ADV7513 does not up because it is not binded : the function "adv7511_bridge_attach" is never called.

What can I do to bind the encoder on DISP output ?

 

Any idea?

Romain
