You can use the label to specify the type, e.g. I would suggest to use something like: mcp2515can: can@0 { ... > + compatible = "microchip,mcp2515"; > + pinctrl-names = "default"; > + pinctrl-0 = <&pinctrl_can_int>; > + reg = <0>; > + clocks = <&clk16m>; > + spi-max-frequency = <10000000>; > + interrupt-parent = <&gpio2>; The interrupt line of the MCP2515 is connected to SODIMM 73, which is PORT1[11] on Vybrid. My recent renaming of the GPIO's has been merged already: https://lkml.org/lkml/2015/1/16/419 Hence, this should be updated to gpio1. > + interrupts = <11 GPIO_ACTIVE_LOW>; > + }; > +}; > + > &esdhc1 { > pinctrl-names = "default"; > pinctrl-0 = <&pinctrl_esdhc1>; > @@ -94,3 +115,13 @@ > &usbh1 { > vbus-supply = <&usbh_vbus_reg>; > }; > + > +&iomuxc { > + vf610-colibri { > + pinctrl_can_int: can_int { > + fsl,pins = < > + VF610_PAD_PTB21__GPIO_43 0x22ed > + >; > + }; > + }; > +}; > diff --git a/arch/arm/boot/dts/vf-colibri.dtsi > b/arch/arm/boot/dts/vf-colibri.dtsi > index 5c2b732..fbef082 100644 > --- a/arch/arm/boot/dts/vf-colibri.dtsi > +++ b/arch/arm/boot/dts/vf-colibri.dtsi > @@ -23,6 +23,12 @@ > status = "okay"; > }; > > +&dspi1 { > + bus-num = <1>; > + pinctrl-names = "default"; > + pinctrl-0 = <&pinctrl_dspi1>; > +}; > + > &edma0 { > status = "okay"; > }; > @@ -107,6 +113,15 @@ > >; > }; > > + pinctrl_dspi1: dspi1grp { > + fsl,pins = < > + VF610_PAD_PTD5__DSPI1_CS0 0x33e2 > + VF610_PAD_PTD6__DSPI1_SIN 0x33e1 > + VF610_PAD_PTD7__DSPI1_SOUT 0x33e2 > + VF610_PAD_PTD8__DSPI1_SCK 0x33e2 > + >; > + }; > + > pinctrl_esdhc1: esdhc1grp { > fsl,pins = < > VF610_PAD_PTA24__ESDHC1_CLK 0x31ef The rest looks good, thx. -- Stefan -- To unsubscribe from this list: send the line "unsubscribe linux-spi" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
