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.
