This does not work properly. You need to declare parent like this:
assigned-clocks = <&clk_s_d0_quadfs 0>, <&clk_s_d0_flexgen CLK_PCM_0>;
assigned-clock-parents = <0>, <&clk_s_d0_quadfs 0>;

assigned-clocks = <&clk_s_d0_quadfs 1>, <&clk_s_d0_flexgen CLK_PCM_1>;
assigned-clock-parents = <0>, <&clk_s_d0_quadfs 1>;
