ARM PL022 SPI controller



Required properties:

- compatible : "arm,pl022", "arm,primecell"

- reg : Offset and length of the register set for the device

- interrupts : Should contain SPI controller interrupt



Optional properties:

- cs-gpios : should specify GPIOs used for chipselects.

  The gpios will be referred to as reg = <index> in the SPI child nodes.

  If unspecified, a single SPI device without a chip select can be used.
