Other Parts Discussed in Thread: TDA2, TVP5158
Hi,
I'm working on custom board with TDA2SX processor,In my board we are using the adv7182 Analog NTSC. I'm facing the issue like below.
root@dra7xx-evm:~# dmesg | grep adv
[ 0.563399] i2c i2c-0: Failed to register i2c client adv7180 at 0x21 (-16)
[ 0.563410] i2c i2c-0: of_i2c: Failure registering /ocp/i2c@48070000/adv7180@21
[ 3.086968] systemd[1]: System time before build time, advancing clock.

The NTSC is connected via i2c1 with slave address as 0x21.
here is my dts information,
&i2c1{
status = "okay";
clock-frequency = <400000>;
adv7180@21 {
compatible = "adi,adv7180";
reg = <0x21>;
status = "okay";
port {
adv7180_1: endpoint{
remore-endpoint=<&vin3a>;
};
};
};
};
&vip1 {
status = "okay";
};
&vin2b {
status = "okay";
endpoint@0 {
slave-mode;
remote-endpoint = <&adv7180_1>;
};
};
Please help me to solve this issue.
Thanks & Regards,
