#define FSL_POWER_DRIVER_VERSION   (MAKE_VERSION(2, 0, 1))

#define LOWPOWER_HWWAKE_FORCED   (1UL << 0)

Force peripheral clocking to stay on during deep-sleep mode.

#define LOWPOWER_HWWAKE_PERIPHERALS   (1UL << 1)

Any Flexcomm FIFO reaching the level specified by its own TXLVL will cause \ peripheral clocking to wake up temporarily while the related status is asserted

#define LOWPOWER_HWWAKE_DMIC   (1UL << 2)

DMIC being busy will cause peripheral clocking to remain running until DMIC \ completes. Used in conjonction with LOWPOWER_HWWAKE_PERIPHERALS

#define LOWPOWER_HWWAKE_SDMA0   (1UL << 3)

DMA0 being busy will cause peripheral clocking to remain running until DMA \ completes. Used in conjonction with LOWPOWER_HWWAKE_PERIPHERALS or LOWPOWER_HWWAKE_DAC
