+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>;
+ };
+ };
