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;
|
|
};
