+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>;
+               };
+       };
