Davinci SPI controller device bindings

Required properties:
- #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.
- compatible:
- "ti,dm6441-spi" for SPI used similar to that on DM644x SoC family
- "ti,da830-spi" for SPI used similar to that on DA8xx SoC family
- reg: Offset and length of SPI controller register space
- num-cs: Number of chip selects
- ti,davinci-spi-intr-line: interrupt line used to connect the SPI
IP to the interrupt controller within the SoC. Possible values
are 0 and 1. Manual says one of the two possible interrupt
lines can be tied to the interrupt controller. Set this
based on a specifc SoC configuration.
- interrupts: interrupt number mapped to CPU.
- clocks: spi clk phandle

Example of a NOR flash slave device (n25q032) connected to DaVinci
SPI controller device over the SPI bus.

spi0:spi@20BF0000 {
#address-cells = <1>;
#size-cells = <0>;
compatible = "ti,dm6446-spi";
reg = <0x20BF0000 0x1000>;
num-cs = <4>;
ti,davinci-spi-intr-line = <0>;
interrupts = <338>;
clocks = <&clkspi>;

flash: n25q032@0 {
#address-cells = <1>;
#size-cells = <1>;
compatible = "st,m25p32";
spi-max-frequency = <25000000>;
reg = <0>;

partition@0 {
label = "u-boot-spl";
reg = <0x0 0x80000>;
read-only;
};

partition@1 {
label = "test";
reg = <0x80000 0x380000>;
};
};
};
