1* Microchip WILC wireless SDIO device 2 3The wilc1000 chips can be connected via SDIO. The node is used to specifiy 4child node to the SDIO controller that connects the device to the system. 5 6Required properties: 7- compatible : Should be "microchip,wilc1000-spi" 8- irq-gpios : Connect to a host IRQ 9- reg : Slot ID used in the controller 10 11Optional: 12- bus-width : Number of data lines wired up the slot. Default 1 bit. 13- rtc_clk : Clock connected on the rtc clock line. Must be assigned 14 a frequency with assigned-clocks property, and must be 15 connected to a clock provider. 16 17Examples: 18mmc1: mmc@fc000000 { 19 pinctrl-names = "default"; 20 pinctrl-0 = <&pinctrl_mmc1_clk_cmd_dat0 &pinctrl_mmc1_dat1_3>; 21 non-removable; 22 vmmc-supply = <&vcc_mmc1_reg>; 23 vqmmc-supply = <&vcc_3v3_reg>; 24 status = "okay"; 25 26 wilc_sdio@0 { 27 compatible = "microchip,wilc1000-sdio"; 28 irq-gpios = <&pioC 27 0>; 29 clocks = <&pck1>; 30 clock-names = "rtc_clk"; 31 assigned-clocks = <&pck1>; 32 assigned-clock-rates = <32768>; 33 status = "okay"; 34 reg = <0>; 35 bus-width = <4>; 36 } 37 }; 38} 39
