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-binding.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>;

};
