STMicroelectronics SSC (SPI) Controller
---------------------------------------
Required properties:
- compatible : "st,comms-ssc4-spi"
- reg : Offset and length of the device's register set
- interrupts : The interrupt specifier
- clock-names : Must contain "ssc"
- clocks : Must contain an entry for each name in clock-names
See ../clk/*
- pinctrl-names : Uses "default", can use "sleep" if provided
See ../pinctrl/pinctrl-bindings.txt
Optional properties:
- cs-gpios : List of GPIO chip selects
See ../spi/spi-bus.txt
Child nodes represent devices on the SPI bus
See ../spi/spi-bus.txt
Example:
spi@9840000 {
compatible = "st,comms-ssc4-spi";
reg = <0x9840000 0x110>;
interrupts = <GIC_SPI 112 IRQ_TYPE_LEVEL_HIGH>;
clocks = <&clk_s_c0_flexgen CLK_EXT2F_A9>;
clock-names = "ssc";
pinctrl-0 = <&pinctrl_spi0_default>;
pinctrl-names = "default";
cs-gpios = <&pio17 5 0>;
#address-cells = <1>;
#size-cells = <0>;
st95hf@0{
compatible = "st,st95hf";
reg = <0>;
spi-max-frequency = <1000000>;
interrupts = <2 IRQ_TYPE_EDGE_FALLING>;
};
};
