Can you please use the same clock order as specified in the dt-bindings?
This means that "pclk_cg" goes before "axi_cg".

				 <&msdc_top CLK_MSDC_TOP_P_MSDC0>,
				 <&msdc_top CLK_MSDC_TOP_AHB2AXI_BRG_AXI>,
				 <&msdc_top CLK_MSDC_TOP_AXI>;
		clock-names = "source", "hclk", "source_cg", "sys_cg",
			      "pclk_cg", "axi_cg", "ahb_cg";

same here please.
