+Device Tree Bindings for the Arasan SDHCI Controller
+
+ The bindings follow the mmc[1], clock[2] and interrupt[3] bindings. Only
+ deviations are documented here.
+
+ [1] Documentation/devicetree/bindings/mmc/mmc.txt
+ [2] Documentation/devicetree/bindings/clock/clock-bindings.txt
+ [3] Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
+
+Required Properties:
+ - compatible: Compatibility string. Must be 'arasan,sdhci-8.9a'
+ - reg: From mmc bindings: Register location and length.
+ - clocks: From clock bindings: Handles to clock inputs.
+ - clock-names: From clock bindings: Tuple including "clk_xin" and "clk_ahb"
+ - interrupts: Interrupt specifier
+ - interrupt-parent: Phandle for the interrupt controller that services
+ interrupts for this device.
+
+Example:
+ sdhci@e0100000 {
+ compatible = "arasan,sdhci-8.9a";
+ reg = <0xe0100000 0x1000>;
+ clock-names = "clk_xin", "clk_ahb";
+ clocks = <&clkc 21>, <&clkc 32>;
+ interrupt-parent = <&gic>;
+ interrupts = <0 24 4>;
+ } ;
