1 Amlogic MesonX device tree bindings
2 -------------------------------------------
4 Work in progress statement:
6 Device tree files and bindings applying to Amlogic SoCs and boards are
7 considered "unstable". Any Amlogic device tree binding may change at
8 any time. Be sure to use a device tree binary and a kernel image
9 generated from the same source tree.

114 The Meson SoCs have a register bank with status and data shared with the
118 - compatible: For Meson GX SoCs, must be "amlogic,meson-gx-ao-secure", "syscon"
120 Properties should indentify components of this register interface :
122 Meson GX SoC Information
