Hello,
these three patches make sure that there's an explicit dependency from the GPIO chip in Tegra SoCs to the corresponding pinctrl device, without having duplicated gpio ranges.
By having an explicit dependency, we can do things such as probing the pinctrl device before the GPIO chip device to avoid deferred probes.
Thanks,
Tomeu
