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:

will send an updated v4...old version was working but i should use the new one.
@Krzysztof can i take your RB here or should i leave it as Patch was changed?
