    4 This documents describes the devicetree bindings for a mmc-host controller
    5 child node describing a mmc-card / an eMMC, see "Use of Function subnodes"

    8 Required properties:
    9 -compatible : Must be "mmc-card"
   10 -reg        : Must be <0>
   11 
   12 Optional properties:
   13 -broken-hpi : Use this to indicate that the mmc-card has a broken hpi
   14               implementation, and that hpi should not be used
   15 
   16 Example:
   17 
   18 &mmc2 {
   19         pinctrl-names = "default";
   20         pinctrl-0 = <&mmc2_pins_a>;
   21         vmmc-supply = <&reg_vcc3v3>;
   22         bus-width = <8>;
   23         non-removable;
   24 
   25         mmccard: mmccard@0 {
   26                 reg = <0>;
   27                 compatible = "mmc-card";
   28                 broken-hpi;
   29         };
