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;
};

};
