-Bindings for HyperBus Memory Controller (HBMC) 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 translation from offset within CS to allocated MMIO
- space in SoC
-
-Optional properties:
-- mux-controls : phandle to the multiplexer that controls selection of
- HBMC vs OSPI inside Flash SubSystem (FSS). Default is OSPI,
- if property is absent.
- See Documentation/devicetree/bindings/mux/reg-mux.yaml
- for mmio-mux binding details
-
-Example:
-
- system-controller@47000000 {
- compatible = "syscon", "simple-mfd";
- reg = <0x0 0x47000000 0x0 0x100>;
- #address-cells = <2>;
- #size-cells = <2>;
- ranges;
-
- hbmc_mux: multiplexer {
- compatible = "mmio-mux";
- #mux-control-cells = <1>;
- mux-reg-masks = <0x4 0x2>; /* 0: reg 0x4, bit 1 */
- };
- };
-
- hbmc: hyperbus@47034000 {
- compatible = "ti,am654-hbmc";
- reg = <0x0 0x47034000 0x0 0x100>,
- <0x5 0x00000000 0x1 0x0000000>;
- power-domains = <&k3_pds 55>;
- #address-cells = <2>;
- #size-cells = <1>;
- ranges = <0x0 0x0 0x5 0x00000000 0x4000000>, /* CS0 - 64MB */
- <0x1 0x0 0x5 0x04000000 0x4000000>; /* CS1 - 64MB */
- mux-controls = <&hbmc_mux 0>;
-
- /* Slave flash node */
- flash@0,0 {
- compatible = "cypress,hyperflash", "cfi-flash";
- reg = <0x0 0x0 0x4000000>;
- };
- };
