Other Parts Discussed in Thread: TDA4VH
Tool/software:
Hi Team,
I want to enable mcan3 and mcan5 on TDA4VH EVM,but got confused by usage of mux1 and mux2.
&main_i2c0 {
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&main_i2c0_pins_default>;

compatible = "ti,tca6416";
reg = <0x20>;

Can you give some insight?
