[PATCH 0/3] soc: amlogic: Add Meson6/8/8b SoC Information driver

[Martin Blumenstingl]

The 32-bit Amlogic SoC have some registers which contain some information
the SoC's major and version, as well as a "major version".
This patchset adds support for this register decoding and exposing with the
SoC bus infrastructure, with dt-bindings and DT node.

This is inspired by Neil's Meson GX socinfo driver, see [0]

All information was taken from Amlogic's 3.10 GPL kernel sources because
the public S805 datasheet from Hardkernel does not contain any relevant
information for these register blocks.
