[PATCH 0/2] arm64: dts: meson: g12a: add secure monitor and efuse

[Jerome Brunet]

This patchset adds the secure monitor and efuse to the g12a SoC family.
These are sent together because the secure monitor is required for the
efuse driver to work properly. This is probably something the bindings
should show but it was not designed that way when the secure monitor was
introduced ... something to look at someday.
