Well, such a feature doesn't exist yet. But, I envisaged extending the existing: pmx = pinmux_get() pinmux_enable(pmx) ... pinmux_disable(pmx) pinmux_put(pmx) to something like: pmx = pinmux_get(active) pinmux_enable(pmx) ... pinmux_switch(suspend) ... pinmux_switch(active) ... pinmux_disable(pmx) pinmux_put(pmx) (I think LinusW proposed an alternative a while back last time we talked about this) This has received only limited discussion though, and there are probably many gotchas to think through; I imagine any such feature is a way off. -- nvpublic -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
