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 |
|
|
|
Optional properties: |
|
- cfam-reset-gpios: GPIO for CFAM reset |
|
|
|
- fsi-routing-gpios: GPIO for setting the FSI mux (internal or cabled) |
|
- fsi-mux-gpios: GPIO for detecting the desired FSI mux 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>; |
|
|
|
fsi-routing-gpios = <&gpio0 ASPEED_GPIO(Q, 7) GPIO_ACTIVE_HIGH>; |
|
fsi-mux-gpios = <&gpio0 ASPEED_GPIO(B, 0) GPIO_ACTIVE_HIGH>; |
|
|
|
cfam-reset-gpios = <&gpio0 ASPEED_GPIO(Q, 0) GPIO_ACTIVE_LOW>; |
|
};
