The CSR SiRF prima2/atlas platforms are getting removed, so this driver
is no longer needed.

* CSR SiRFprimaII Serial Peripheral Interface



Required properties:

- compatible : Should be "sirf,prima2-spi", "sirf,prima2-usp"

               or "sirf,atlas7-usp"

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

- interrupts : Should contain SPI interrupt

- resets: phandle to the reset controller asserting this device in

          reset

  See ../reset/reset.txt for details.

- dmas : Must contain an entry for each entry in clock-names.

  See ../dma/dma.txt for details.

- dma-names : Must include the following entries:

  - rx

  - tx

- clocks : Must contain an entry for each entry in clock-names.

  See ../clocks/clock-bindings.txt for details.



- #address-cells: Number of cells required to define a chip select

                  address on the SPI bus. Should be set to 1.

- #size-cells:    Should be zero.



Optional properties:

- spi-max-frequency: Specifies maximum SPI clock frequency,

                     Units - Hz. Definition as per

                     Documentation/devicetree/bindings/spi/spi-bus.txt

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



Example:



spi0: spi@b00d0000 {

	compatible = "sirf,prima2-spi";

	reg = <0xb00d0000 0x10000>;

	interrupts = <15>;

	dmas = <&dmac1 9>,

		<&dmac1 4>;

	dma-names = "rx", "tx";

	#address-cells = <1>;

	#size-cells = <0>;

	clocks = <&clks 19>;

	resets = <&rstc 26>;

};
