In general, the use of a wildcard compatible string is discouraged over the use of a more descriptive compatible string. So you should find out what is the first chip that is compatible, and use that compatible string as long as that compatibility remains. > + > +Optional properties: > + - brcm,drive-strength : drive strength used for SDIO pins on device. > + (default = 6mA). It would not hurt if you did specify the unit of the "brcm,drive-strength" property here. Also, if the default is 6, maybe the example below should be fixed to reflect that so people do not think that writing 4 to a register = 6 mA. > + - interrupt-parent : the phandle for the interrupt controller to which the > + device interrupts are connected. > + - interrupts : specifies attributes for the out-of-band interrupt > (host-wake). > + When not specified the device will use in-band SDIO interrupts. > + - interrupt-names : name of the out-of-band interrupt, which must be set > + to "host-wake". > + > +Example: > + > +bcm4335 { > + compatible = "brcm,bcm43xx-fmac"; > + brcm,drive-strength = <4>; > + interrupt-parent = <&gpx2>; > + interrupts = <5 IRQ_TYPE_LEVEL_HIGH>; > + interrupt-names = "host-wake"; > +}; > -- > 2.0.0 > > > _______________________________________________ > linux-arm-kernel mailing list > linux-arm-ker...@lists.infradead.org > http://lists.infradead.org/mailman/listinfo/linux-arm-kernel -- Florian -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
