[PATCH 00/10] spi: Adding support for Microchip Sparx5 SoC

[Lars Povlsen]

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.
