Device-tree bindings for AST2600 FSI master
|
|
-------------------------------------------
|
|
|
|
The AST2600 contains two identical FSI masters. They share a clock and have a
|
|
separate interrupt line and output pins.
|
|
|
|
Required properties:
|
|
- compatible: "aspeed,ast2600-fsi-master"
|
|
- reg: base address and length
|
|
- clocks: phandle and clock number
|
|
- interrupts: platform dependent interrupt description
|
|
- pinctrl-0: phandle to pinctrl node
|
|
- pinctrl-names: pinctrl state
|
|
|
|
Examples:
|
|
|
|
fsi-master {
|
|
compatible = "aspeed,ast2600-fsi-master", "fsi-master";
|
|
reg = <0x1e79b000 0x94>;
|
|
interrupts = <GIC_SPI 100 IRQ_TYPE_LEVEL_HIGH>;
|
|
pinctrl-names = "default";
|
|
pinctrl-0 = <&pinctrl_fsi1_default>;
|
|
clocks = <&syscon ASPEED_CLK_GATE_FSICLK>;
|
|
};
