    ARM: mxs: enable pinctrl dummy states · d1654b80
    Shawn Guo 提交于
    The mxs pinctrl driver will only support DT probe.  That said, the mxs
    device drivers can only get pinctrl state from pinctrl subsystem when
    the drivers get probed from device tree.
    
    Before converting the whole mxs platform support over to device tree,
    we need to enable pinctrl dummy states for those non-DT board files
    to ensure the pinctrl API adopted by mxs device drivers will work for
    both DT and non-DT probe.
    
    Instead of calling pinctrl_provide_dummies() directly in every board
    file, the patch introduces soc specific calls mx23_soc_init() and
    mx28_soc_init() for boards' .init_machine hook to invoke, so that
    any soc specific setup for non-DT boot only can be added there.
