ipg clock is the IMX6UL_CLK_IPG, for PGC, the arm PGC is available and can also be added to fix the dtbs_check issue.

pgc {
        #address-cells = <1>;
        #size-cells = <0>;

        power-domain at 0 {
                reg = <0>;
                #power-domain-cells = <0>;
        };
};

You will submit a fix or need NXP to do that?
