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 :

|
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;
|
|
};
