Caninos Loucos Labrador is a Brazilian project of open System on Modules and
Base Boards based on Lemaker Guitar. Is an initiative of LSI-TEC a non-profit
organization.
The Labrador SoM v2 is based on Actions Semi S500 processor with 16GB eMMC and
2GB RAM.
This series adds the initial work for device tree files and also adds the
vendor-prefix for the Caninos program. The work was based on the Andreas Färber
device trees for Lemaker Guitar, thanks Andreas.
Tested on my Caninos Labrador v2, only earlycon serial output is available for
now, using the fake clock. I have already worked on something here to add the
clocks and pinctrl nodes to owl-s500.dtsi, but I would like to first add the
initial device tree files and then work on the other patches calmly.
BR,
Matheus Castello

A title here would be helpful like how you added for the SoM below.
