Browse Source 
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>;
};
