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;
};
