    pinctrl/pinconfig: add debug interface · 6f9e41f4
    Laurent Meunier authored
    This update adds a debugfs interface to modify a pin configuration
    for a given state in the pinctrl map. This allows to modify the
    configuration for a non-active state, typically sleep state.
    This configuration is not applied right away, but only when the state
    will be entered.
    
    This solution is mandated for us by HW validation: in order
    to test and verify several pin configurations during sleep without
    recompiling the software.
