Amlogic MesonX device tree bindings
-------------------------------------------

Work in progress statement:

Device tree files and bindings applying to Amlogic SoCs and boards are
considered "unstable". Any Amlogic device tree binding may change at
any time. Be sure to use a device tree binary and a kernel image
generated from the same source tree.

Please refer to Documentation/devicetree/bindings/ABI.txt for a definition of a
stable binding/ABI.

Amlogic Meson Firmware registers Interface
------------------------------------------

The Meson SoCs have a register bank with status and data shared with the
secure firmware.

Required properties:
 - compatible: For Meson GX SoCs, must be "amlogic,meson-gx-ao-secure", "syscon"

Properties should indentify components of this register interface :

Meson GX SoC Information
------------------------
A firmware register encodes the SoC type, package and revision information on
the Meson GX SoCs.
If present, the following property should be added :

Optional properties:
  - amlogic,has-chip-id: If present, the interface gives the current SoC version.

Example
-------

ao-secure@140 {
	compatible = "amlogic,meson-gx-ao-secure", "syscon";
	reg = <0x0 0x140 0x0 0x140>;
	amlogic,has-chip-id;
};
