    pinctrl: Support stopping deferred probe after initcalls · d19c5e79
    Rob Herring authored
    Pinctrl drivers are a common dependency which can prevent a system
    booting even if the default or bootloader configured settings can work.
    If a pinctrl node in DT indicates that the default pin setup can be used
    with the 'pinctrl-use-default' property, then only defer probe until
    initcalls are done. If the deferred probe timeout is enabled or loadable
    modules are disabled, then we'll stop deferring probe regardless of the
    DT property. This gives platforms the option to work without their
    pinctrl driver being enabled.
    
    Dropped the pinctrl specific deferring probe message as the driver core
    can print deferred probe related messages if needed.
