    +Bindings for Hyperbus Memory Controller on TI's K3 family of SoCs
    +
    +Required properties:
    +- compatible : "ti,am654-hbmc" for AM654 SoC
    +- reg : Two entries:
    + First entry pointed to the register space of HBMC controller
    + Second entry pointing to the memory map region dedicated for
    + MMIO access to attached flash devices
    +- ranges : Address range allocated for each Chipselect in the MMIO space
    +
    +Example:
    + hbmc: hbmc@47034000 {
    + compatible = "ti,am654-hbmc";
    + reg = <0x0 0x47034000 0x0 0x100>,
    + <0x5 0x00000000 0x1 0x0000000>;
    + power-domains = <&k3_pds 55>;
    + #address-cells = <1>;
    + #size-cells = <1>;
    + ranges = <0x0 0x5 0x00000000 0x4000000>, /* CS0 - 64MB */
    + <0x1 0x5 0x04000000 0x4000000>; /* CS1 - 64MB
    +
    + /* Slave flash node */
    + flash@0{
    + compatible = "cypress,hyperflash";
    + reg = <0x0 0x4000000>;
