There are three register areas which contain information about the SoC version and revision: - the assist registers contain the SoC's "major version" which encodes the SoC generation and part number. this is available on Meson6, Meson8 and Meson8b SoCs. - the bootrom register contains at least the SoCs "misc version". this is avilable on Meson6, Meson8 and Meson8b - the analog top registers contain information about the SoC revision. this is only available on Meson8 and Meson8b Not much else is currently known about these registers.

Amlogic Meson6/Meson8/Meson8b assist registers:
|
|
-----------------------------------------------
|
|
|
|
The assist registers contain basic information about the SoC,
|
|
for example the encoded SoC part number.
|
|
|
|
Required properties:
|
|
- reg: the register range of the assist registers
|
|
- compatible: should be "amlogic,meson-mx-assist" along with "syscon"
|
|
|
|
|
|
Example:
|
|
|
|
assist: assist@7c00 {
|
|
compatible = "amlogic,meson-mx-assist", "syscon";
|
|
reg = <0x7c00 0x200>;
|
|
};
