+mmc-card / eMMC bindings
+------------------------
+
+This documents describes the devicetree bindings for a mmc-host controller
+child node describing a mmc-card / an eMMC, see "Use of Function subnodes"
+in mmc.txt
+
+Required properties:
+-compatible : Must be "mmc-card"
+-reg : Must be <0>
+
+Optional properties:
+-broken-hpi : Use this to indicate that the mmc-card has a broken hpi
+ implementation, and that hpi should not be used
+
+Example:
+
+&mmc2 {
+ pinctrl-names = "default";
+ pinctrl-0 = <&mmc2_pins_a>;
+ vmmc-supply = <&reg_vcc3v3>;
+ bus-width = <8>;
+ non-removable;
+
+ mmccard: mmccard@0 {
+ reg = <0>;
+ compatible = "mmc-card";
+ broken-hpi;
+ };
+};
