Lets do not degrade this to an arbitrary number. We should use prefixes like '4bit', '100mhz' or combinations thereof for further options. Sascha

The 'x' includes different mux or config. It may be hard to name for all different configs since it's board related. However i don't think it's bad idea for this case. How about pinctrl_usdhc3_3_100mhz and pinctrl_usdhc3_3_200mhz? e.g. pinctrl_usdhc3_3: usdhc3grp-3 { /* default */ fsl,pins = <...>; } pinctrl_usdhc3_3_100mhz: usdhc3grp-3-100mhz { fsl,pins = <...>; } pinctrl_usdhc3_3_200mhz: usdhc3grp-3-200mhz { fsl,pins = <...>; } Regards Dong Aisheng > Sascha > > -- > Pengutronix e.K. | | > Industrial Linux Solutions | http://www.pengutronix.de/ | > Peiner Str. 6-8, 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | > Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 | > > _______________________________________________ > linux-arm-kernel mailing list > linux-arm-kernel@lists.infradead.org > http://lists.infradead.org/mailman/listinfo/linux-arm-kernel -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
