    pinctrl: tegra: Move drivers registration to arch_init level · 1e0813ee
    Dmitry Osipenko authored
    There is a bug in regards to deferred probing within the drivers core
    that causes GPIO-driver to suspend after its users. The bug appears if
    GPIO-driver probe is getting deferred, which happens after introducing
    dependency on PINCTRL-driver for the GPIO-driver by defining "gpio-ranges"
    property in device-tree. The bug in the drivers core is old (more than 4
    years now) and is well known, unfortunately there is no easy fix for it.
    The good news is that we can workaround the deferred probe issue by
    changing GPIO / PINCTRL drivers registration order and hence by moving
    PINCTRL driver registration to the arch_init level and GPIO to the
    subsys_init.
