In the last stage of deep sleep, software will trigger a Finite State Machine (FSM) to control the hardware procedure, such a board isolation, killing PLLs, removing power, and so on. When the system is waked up by an interrupt, the FSM controls the hardware to complete the early resume procedure. This patch configure the EPU FSM preparing for deep sleep.

config FSL_GUTS bool select SOC_BUS help The global utilities block controls power management, I/O device enabling, power-onreset(POR) configuration monitoring, alternate function selection for multiplexed signals,and clock control. This driver is to manage and access global utilities block. Initially only reading SVR and registering soc device are supported. Other guts accesses, such as reading RCW, should eventually be moved into this driver as well.
config FSL_MC_DPIO tristate "QorIQ DPAA2 DPIO driver" depends on FSL_MC_BUS select SOC_BUS select FSL_GUTS select DIMLIB help Driver for the DPAA2 DPIO object. A DPIO provides queue and buffer management facilities for software to interact with other DPAA2 objects. This driver does not expose the DPIO objects individually, but groups them under a service layer API.
config FSL_SLEEP_FSM bool help This driver configures a hardware FSM (Finite State Machine) for deep sleep. The FSM is used to finish clean-ups at the last stage of system entering deep sleep, and also wakes up system when a wake up event happens.
config DPAA2_CONSOLE tristate "QorIQ DPAA2 console driver" depends on OF && (ARCH_LAYERSCAPE || COMPILE_TEST) default y help Console driver for DPAA2 platforms. Exports 2 char devices, /dev/dpaa2_mc_console and /dev/dpaa2_aiop_console, which can be used to dump the Management Complex and AIOP firmware logs.
config FSL_RCPM bool "Freescale RCPM support" depends on PM_SLEEP && (ARM || ARM64) help The NXP QorIQ Processors based on ARM Core have RCPM module (Run Control and Power Management), which performs all device-level tasks associated with power management, such as wakeup source control. Note that currently this driver will not support PowerPC based QorIQ processor.
config FSL_QIXIS tristate "QIXIS system controller driver" depends on OF select REGMAP_I2C select REGMAP_MMIO default n help Say y here to enable QIXIS system controller api. The qixis driver provides FPGA functions to control system.
