dt-bindings: mmc: socionext,milbeaut-m10v-sdhci-3.0: convert to DT schema 



Convert SOCIONEXT Milbeaut SDHCI controller binding to YAML format.
Add a new property "voltage-ranges" to resolve dt_check errors.

* 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



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;

		fujitsu,cmd-dat-delay-select;

	};

description:

  The SOCIONEXT Milbeaut SDHCI controller is a specialized SD Host

  Controller found in some of Socionext's Milbeaut image processing SoCs.

  It features a dedicated "bridge controller." This bridge controller

  implements special functions like reset control, clock management for

  various SDR modes (SDR12, SDR25, SDR50) and physical pin property settings.
