This is an add-on series to the main SoC Sparx5 series (Message-ID: <20200513125532.24585-1-lars.povlsen@xxxxxxxxxxxxx>). The series add support for Sparx5 on top of the existing ocelot/jaguar2 spi driver. It spins off the existing support for the MSCC platforms into a separate driver, as adding new platforms from the MSCC/Microchip product lines will further complicate (clutter) the original driver. New YAML dt-bindings are provided for the resulting driver. It is expected that the DT patches are to be taken directly by the arm-soc maintainers.
