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 Meson8 and Meson8b "analog top" registers:
|
|
--------------------------------------------------
|
|
|
|
The analog top registers contain information about the so-called
|
|
"metal revision" (which encodes the "minor version") of the SoC.
|
|
|
|
Required properties:
|
|
- reg: the register range of the analog top registers
|
|
- compatible: depending on the SoC this should be one of:
|
|
- "amlogic,meson8-analog-top"
|
|
- "amlogic,meson8b-analog-top"
|
|
along with "syscon"
|
|
|
|
|
|
Example:
|
|
|
|
analog_top: analog-top@81a8 {
|
|
compatible = "amlogic,meson8-analog-top", "syscon";
|
|
reg = <0x81a8 0x14>;
|
|
};
