SPI Master controller for Netlogic XLP MIPS64 SOCs
|
|
==================================================
|
|
|
|
Currently this SPI controller driver is supported for the following
|
|
Netlogic XLP SoCs:
|
|
XLP832, XLP316, XLP208, XLP980, XLP532
|
|
|
|
Required properties:
|
|
- compatible : Should be "netlogic,xlp832-spi".
|
|
- #address-cells : Number of cells required to define a chip select address
|
|
on the SPI bus.
|
|
- #size-cells : Should be zero.
|
|
- reg : Should contain register location and length.
|
|
- clocks : Phandle of the spi clock
|
|
- interrupts : Interrupt number used by this controller.
|
|
- interrupt-parent : Phandle of the parent interrupt controller.
|
|
|
|
SPI slave nodes must be children of the SPI master node and can contain
|
|
properties described in Documentation/devicetree/bindings/spi/spi-bus.txt.
|
|
|
|
Example:
|
|
|
|
spi: xlp_spi@3a100 {
|
|
compatible = "netlogic,xlp832-spi";
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
reg = <0 0x3a100 0x100>;
|
|
clocks = <&spi_clk>;
|
|
interrupts = <34>;
|
|
interrupt-parent = <&pic>;
|
|
|
|
spi_nor@1 {
|
|
compatible = "spansion,s25sl12801";
|
|
#address-cells = <1>;
|
|
#size-cells = <1>;
|
|
reg = <1>; /* Chip Select */
|
|
spi-max-frequency = <40000000>;
|
|
};
|
|
};
