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>; }; |
