-* Amlogic Meson6, Meson8 and Meson8b SDIO/MMC controller
-
-The highspeed MMC host controller on Amlogic SoCs provides an interface
-for MMC, SD, SDIO and SDHC types of memory cards.
-
-Supported maximum speeds are the ones of the eMMC standard 4.41 as well
-as the speed of SD standard 2.0.
-
-The hardware provides an internal "mux" which allows up to three slots
-to be controlled. Only one slot can be accessed at a time.
-
-Required properties:
- - compatible : must be one of
-	- "amlogic,meson8-sdio"
-	- "amlogic,meson8b-sdio"
-	along with the generic "amlogic,meson-mx-sdio"
- - reg : mmc controller base registers
- - interrupts : mmc controller interrupt
- - #address-cells : must be 1
- - size-cells : must be 0
- - clocks : phandle to clock providers
- - clock-names : must contain "core" and "clkin"
-
-Required child nodes:
-A node for each slot provided by the MMC controller is required.
-NOTE: due to a driver limitation currently only one slot (= child node)
-      is supported!
-
-Required properties on each child node (= slot):
- - compatible : must be "mmc-slot" (see mmc.txt within this directory)
- - reg : the slot (or "port") ID
-
-Optional properties on each child node (= slot):
- - bus-width : must be 1 or 4 (8-bit bus is not supported)
- - for cd and all other additional generic mmc parameters
-   please refer to mmc.txt within this directory
-
-Examples:
-	mmc@c1108c20 {
-		compatible = "amlogic,meson8-sdio", "amlogic,meson-mx-sdio";
-		reg = <0xc1108c20 0x20>;
-		interrupts = <0 28 1>;
-		#address-cells = <1>;
-		#size-cells = <0>;
-		clocks = <&clkc CLKID_SDIO>, <&clkc CLKID_CLK81>;
-		clock-names = "core", "clkin";
-
-		slot@1 {
-			compatible = "mmc-slot";
-			reg = <1>;
-
-			bus-width = <4>;
-		};
-	};
