-Required properties:
-- #address-cells: see spi-bus.txt
-- #size-cells: see spi-bus.txt
-- compatible: should be "energymicro,efm32-spi"
-- reg: Offset and length of the register set for the controller
-- interrupts: pair specifying rx and tx irq
-- clocks: phandle to the spi clock
-- cs-gpios: see spi-bus.txt
-
-Recommended properties :
-- energymicro,location: Value to write to the ROUTE register's LOCATION
