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>;
};
