Hi,

got another config from mtk which requires changing binding a bit

                       clocks = <&topckgen CLK_TOP_EMMC_416M_SEL>,
                                <&infracfg CLK_INFRA_MSDC_HCK_CK>,
                                <&infracfg CLK_INFRA_MSDC_CK>,
                                <&infracfg CLK_INFRA_MSDC_133M_CK>,
                                 <&infracfg CLK_INFRA_MSDC_66M_CK>;
                       clock-names = "source", "hclk", "source_cg", "bus_clk",
                                     "sys_cg";
in binding:
