Hi Konrad,

  Did you mean adding the following node:

         typec-mux@42 {
                 compatible = "fcs,fsa4480";
                 reg = <0x42>;

                 interrupts-extended = <&tlmm 2 IRQ_TYPE_LEVEL_LOW>;

                 vcc-supply = <&vreg_bob>;
                 mode-switch;
                 orientation-switch;

                 port {
                         fsa4480_sbu_mux: endpoint {
                                 remote-endpoint = <&pmic_glink_sbu>;
                         };
                 };
         };


and then adding port-2 for pmic_glink ?

Usually for role-switch the port-0/1 defined in this patch are 
sufficient. Also if I added it, I don't have a way to currently test it. 
So skipped this node. I will try and see if I can test it and add it if 
possible.

Regards,
Krishna,
