1ARM Freescale DSPI controller 2 3Required properties: 4- compatible : "fsl,vf610-dspi" 5- reg : Offset and length of the register set for the device 6- interrupts : Should contain SPI controller interrupt 7- clocks: from common clock binding: handle to dspi clock. 8- clock-names: from common clock binding: Shall be "dspi". 9- pinctrl-0: pin control group to be used for this controller. 10- pinctrl-names: must contain a "default" entry. 11- spi-num-chipselects : the number of the chipselect signals. 12- bus-num : the slave chip chipselect signal number. 13 14Optional property: 15- big-endian: If present the dspi device's registers are implemented 16 in big endian mode, otherwise in native mode(same with CPU), for more 17 detail please see: Documentation/devicetree/bindings/regmap/regmap.txt. 18 19Example: 20 21dspi0@4002c000 { 22 #address-cells = <1>; 23 #size-cells = <0>; 24 compatible = "fsl,vf610-dspi"; 25 reg = <0x4002c000 0x1000>; 26 interrupts = <0 67 0x04>; 27 clocks = <&clks VF610_CLK_DSPI0>; 28 clock-names = "dspi"; 29 spi-num-chipselects = <5>; 30 bus-num = <0>; 31 pinctrl-names = "default"; 32 pinctrl-0 = <&pinctrl_dspi0_1>; 33 big-endian; 34 status = "okay"; 35 36 sflash: at26df081a@0 { 37 #address-cells = <1>; 38 #size-cells = <1>; 39 compatible = "atmel,at26df081a"; 40 spi-max-frequency = <16000000>; 41 spi-cpol; 42 spi-cpha; 43 reg = <0>; 44 linux,modalias = "m25p80"; 45 modal = "at26df081a"; 46 }; 47}; 48 49 50
