1Amlogic MesonX device tree bindings
2-------------------------------------------
3
4Work in progress statement:
5
6Device tree files and bindings applying to Amlogic SoCs and boards are
7considered "unstable". Any Amlogic device tree binding may change at
8any time. Be sure to use a device tree binary and a kernel image
9generated from the same source tree.
10
11Please refer to Documentation/devicetree/bindings/ABI.txt for a definition of a
12stable binding/ABI.

113Amlogic Meson Firmware registers Interface
114------------------------------------------
115
116The Meson SoCs have a register bank with status and data shared with the
117secure firmware.
118
119Required properties:
120 - compatible: For Meson GX SoCs, must be "amlogic,meson-gx-ao-secure", "syscon"
121
122Properties should indentify components of this register interface :
123
124Meson GX SoC Information
125------------------------
126A firmware register encodes the SoC type, package and revision information on
127the Meson GX SoCs.
128If present, the following property should be added :
129
130Optional properties:
131 - amlogic,has-chip-id: If present, the interface gives the current SoC version.
132
