It's not scalable and there's no actual guarantee it'll produce the desired result. Instead, if one device depends on another, it should do so explicitly. In other words, the device that relies on a particular pinctrl setting should have a pinctrl state defined, that references the pin controller, which then triggers deferred probe until the pin controller is initialized. Since we initialize the whole pinctrl setup in one go in a state associated with the pin controller, rather than as separate states associated with each device, you'll need to have the leaf devices reference an empty pinctrl state defined in the desired pin controller. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
