1Atmel SPI device
2
3Required properties:
4- compatible : should be "atmel,at91rm9200-spi" or "microchip,sam9x60-spi".
5- reg: Address and length of the register set for the device
6- interrupts: Should contain spi interrupt
7- cs-gpios: chipselects (optional for SPI controller version >= 2 with the
8  Chip Select Active After Transfer feature).
9- clock-names: tuple listing input clock names.
10	Required elements: "spi_clk"
11- clocks: phandles to input clocks.
12
13Optional properties:
14- atmel,fifo-size: maximum number of data the RX and TX FIFOs can store for FIFO
15  capable SPI controllers.
