Convert the Renesas Serial Communication Interface ((H)SCI(F)(A|B)) Device Tree binding documentation to json-schema. Split the bindings in 5 files, one per major type, to ease expressing constraints. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Rob Herring <robh@kernel.org>
