1* CSR SiRFprimaII Serial Peripheral Interface
2
3Required properties:
4- compatible : Should be "sirf,prima2-spi"
5- reg : Offset and length of the register set for the device
6- interrupts : Should contain SPI interrupt
7- resets: phandle to the reset controller asserting this device in
8          reset
9  See ../reset/reset.txt for details.
10- dmas : Must contain an entry for each entry in clock-names.
11  See ../dma/dma.txt for details.
12- dma-names : Must include the following entries:
13  - rx
14  - tx
15- clocks : Must contain an entry for each entry in clock-names.
16  See ../clocks/clock-bindings.txt for details.

18- #address-cells: Number of cells required to define a chip select
19                  address on the SPI bus. Should be set to 1.
20- #size-cells:    Should be zero.
21
22Optional properties:
23- spi-max-frequency: Specifies maximum SPI clock frequency,
24                     Units - Hz. Definition as per
25                     Documentation/devicetree/bindings/spi/spi-bus.txt
26- cs-gpios:     should specify GPIOs used for chipselects.
