-* Allwinner sunxi MMC controller
-
-The highspeed MMC host controller on Allwinner SoCs provides an interface
-for MMC, SD and SDIO types of memory cards.
-
-Supported maximum speeds are the ones of the eMMC standard 4.5 as well
-as the speed of SD standard 3.0.
-Absolute maximum transfer rate is 200MB/s
-
-Required properties:
- - compatible : "allwinner,sun4i-a10-mmc" or "allwinner,sun5i-a13-mmc"
- - reg : mmc controller base registers
- - clocks : a list with 2 phandle + clock specifier pairs
- - clock-names : must contain "ahb" and "mmc"
- - interrupts : mmc controller interrupt
-
-Optional properties:
- - resets : phandle + reset specifier pair
- - reset-names : must contain "ahb"
- - for cd, bus-width and additional generic mmc parameters
-   please refer to mmc.txt within this directory
-
-Examples:
-       - Within .dtsi:
-       mmc0: mmc@01c0f000 {
-               compatible = "allwinner,sun5i-a13-mmc";
-               reg = <0x01c0f000 0x1000>;
-               clocks = <&ahb_gates 8>, <&mmc0_clk>;
-               clock-names = "ahb", "mod";
-               interrupts = <0 32 4>;
-               status = "disabled";
-       };
-
-       - Within dts:
-       mmc0: mmc@01c0f000 {
-               pinctrl-names = "default", "default";
-               pinctrl-0 = <&mmc0_pins_a>;
-               pinctrl-1 = <&mmc0_cd_pin_reference_design>;
-               bus-width = <4>;
-               cd-gpios = <&pio 7 1 0>; /* PH1 */
-               cd-inverted;
-               status = "okay";
-       };
