Well, there is gpio-feature and gpio-pmf right now. I suspect you can get things working by adding some overrides to ftr_gpio_init(). I guess you want something like get_gpio("keywest-gpio1", NULL, &lineout_mute_gpio, &lineout_mute_gpio_activestate); on the PowerMac4,3, and something else for the headphone ... But frankly, it's been so long that it's not all making perfect sense to me right now. If you send me a tarball of /proc/device-tree/ maybe I can take a look -- just looked at my collection and I don't have that one. johannes _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
