| 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; |
| }; |
