Hi,

I haven't found any information regarding support for nested i2c muxes.
Is the below device tree supported by the current driver ?

&i2c0 {
        status = "okay";
        clock-frequency = <400000>;
        pinctrl-names = "default";
        pinctrl-0 = <&pinctrl_i2c0_default>;

        i2cswitch@74 {
                compatible = "nxp,pca9548";
                #address-cells = <1>;
                #size-cells = <0>;
                reg = <0x74>;

                i2c@0 {
                        #address-cells = <1>;
                        #size-cells = <0>;
                        reg = <0>;
                        si570: clock-generator@5d {
                                #clock-cells = <0>;
                                compatible = "silabs,si570";
                                temperature-stability = <50>;
                                reg = <0x5d>;
                                factory-fout = <156250000>;
                                clock-frequency = <148500000>;
                        };
                };

                i2c@2 {
                        #address-cells = <1>;
                        #size-cells = <0>;
                        reg = <5>;
                        i2cswitch_hpc@74 {
                                         compatible = "nxp,pca9548";
                                         #address-cells = <1>;
                                         #size-cells = <0>;
                                         reg = <0x74>;
                                         hpc_caribou_sources_enable@76  {
                                                                       
compatible= "nxp,pca9539";
                                                                       
#address-cells = <1>;
                                                                       
#size-cells = <0>;
                                                                       
reg = <0x76>;
                                         };
                        };

                };

        };

};

With such tree I am getting error

[2.173385] i2c i2c-2: of_i2c: invalid addr=0 on
/amba/i2c@e0004000/i2cswitch@74/i2c@2/i2cswitch_hpc@74
