Most functions on da850 are available only on one physical pin. So every board that needs that functionality needs to setup the pinmux the same way. This was the idea behind adding pinmux to da850.dtsi rather than repeating it for every board. Even though the pinctrl entries are there in da850.dtsi, the pinmux registers wont be touched unless the status is set to "okay" for that device in board .dts file. The only care that needs to be taken is that the pins listed in da850.dtsi need to be the minimum required for achieving that functionality. If a board needs more than what is populated in da850.dtsi then it can define its own pinctrl entries overriding that coming from da850.dtsi Thanks, Sekhar -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
