    NFC: trf7970a: Don't assume CONFIG_PM_RUNTIME is enabled · ceccd6aa
    Mark A. Greer authored
    The current code assumes that CONFIG_PM_RUNTIME
    is always defined so it won't power up the trf7970a
    when it isn't enabled.  Fix this by moving the power
    up/down code from the pm_runtime_resume/suspend
    routines into their own routines and calling the
    power up function from the probe routine.  This
    ensures the device is powered up even when
    CONFIG_PM_RUNTIME is not defined.
    In order to not power on/off a device that is
    already powered on/off, create a new state to
    indicate that the power is off (TRF7970A_ST_PWR_OFF).
