+* SOCIONEXT Milbeaut SDHCI controller
+
+This file documents differences between the core properties in mmc.txt
+and the properties used by the sdhci_milbeaut driver.
+
+Required properties:
+- compatible: "socionext,milbeaut-m10v-sdhci-3.0"
+- clocks: Must contain an entry for each entry in clock-names. It is a
+ list of phandles and clock-specifier pairs.
+ See ../clocks/clock-bindings.txt for details.
+- clock-names: Should contain the following two entries:
+ "iface" - clock used for sdhci interface
+ "core" - core clock for sdhci controller
+- vmmc-supply: a phandle of a fixed GPIO regulator
+
+Optional properties:
+- fujitsu,cmd-dat-delay-select: boolean property indicating that this host
+ requires the CMD_DAT_DELAY control to be enabled.
+
+Example:
+ sdhci3: mmc@1b010000 {
+ compatible = "socionext,milbeaut-m10v-sdhci-3.0";
+ reg = <0x1b010000 0x10000>;
+ interrupts = <0 265 0x4>;
+ voltage-ranges = <3300 3300>;
+ bus-width = <4>;
+ clocks = <&clk 7>, <&ahb_clk>;
+ clock-names = "core", "iface";
+ cap-sdio-irq;
+ vmmc-supply = <&vcc_sdhci3>;
+ fujitsu,cmd-dat-delay-select;
+ };

Being a fixed GPIO regulator is board specific and outside the scope of
the binding. Otherwise,

I see. I will remove vmmc-supply and send new patch.
