+* Cavium Octeon & ThunderX MMC controller
+
+The highspeed MMC host controller on Caviums SoCs provides an interface
+for MMC and SD types of memory cards.
+
+Supported maximum speeds are the ones of the eMMC standard 4.41 as well
+as the speed of SD standard 4.0. Only 3.3 Volt is supported.
+
+Required properties:
+ - compatible : should be one of:
+ cavium,octeon-6130-mmc
+ cavium,octeon-6130-mmc-slot
+ cavium,octeon-7890-mmc
+ cavium,octeon-7890-mmc-slot
+ cavium,thunder-8190-mmc
+ cavium,thunder-8190-mmc-slot
+ cavium,thunder-8390-mmc
+ cavium,thunder-8390-mmc-slot
+ - reg : mmc controller base registers
+ - clocks : phandle
+
+Optional properties:
+ - for cd, bus-width and additional generic mmc parameters
+ please refer to mmc.txt within this directory
+ - cavium,cmd-clk-skew : number of coprocessor clocks before sampling command
+ - cavium,dat-clk-skew : number of coprocessor clocks before sampling data
+
+Deprecated properties:
+- spi-max-frequency : use max-frequency instead
+- cavium,bus-max-width : use bus-width instead
+
+Examples:
+ mmc_1_4: mmc@1,4 {
+ compatible = "cavium,thunder-8390-mmc";
+ reg = <0x0c00 0 0 0 0>; /* DEVFN = 0x0c (1:4) */
+ #address-cells = <1>;
+ #size-cells = <0>;
+ clocks = <&sclk>;
+
+ mmc-slot@0 {
+ compatible = "cavium,thunder-8390-mmc-slot";
+ reg = <0>;
+ voltage-ranges = <3300 3300>;
+ vmmc-supply = <&mmc_supply_3v3>;
+ max-frequency = <42000000>;
+ bus-width = <4>;
+ cap-sd-highspeed;
+ };
+
+ mmc-slot@1 {
+ compatible = "cavium,thunder-8390-mmc-slot";
+ reg = <1>;
+ voltage-ranges = <3300 3300>;
+ vmmc-supply = <&mmc_supply_3v3>;
+ max-frequency = <42000000>;
+ bus-width = <8>;
+ cap-mmc-highspeed;
+ non-removable;
+ };
+ };
