Martin Blumenstingl aee2828ccb dt-bindings: Amlogic: add documentation for the SoC info register areas
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 bootrom:
--------------------------------------
The bootrom register area can be used to access SoC specific
information, such as the "misc version".
Required properties:
- reg: the register range of the bootrom registers
- compatible: should be "amlogic,meson-mx-bootrom" along with "syscon"
Example:
bootrom: bootrom@d9040000 {
compatible = "amlogic,meson-mx-bootrom", "syscon";
reg = <0xd9040000 0x10000>;
};
