IMX7D contains a new version of GPC IP block (GPCv2). It has two
major functions: power management and wakeup source management.
Two drivers were developed to support these functions:
One irqchip driver (irq-imx-gpcv2.c) is to manage
the interrupt wakeup source. One suspend driver (pm-imx7.c) is used
to manage the system power states.
Patch V6:
Clean up the codes (irq-imx-gpcv2.c) according to the review
feedback of Thomas Glx
Use raw_spin_lock in the irq_mask and irq_unmask callbacks
Split the struct definition into two: irqchip and suspend
Unified coding style
Patch V5:
Splitted it into two patches per Thomas Gleixner suggestion.
-- one for irqchip
-- one for suspend
Patch V4:
Splitted the driver into two function drivers: one irqchip driver
for wakeup source management, and one suspend driver for power
state management.
Patch V3:
Added the assemble codes (suspend-imx7.S) for SUSPEND_MEM state.
Supported the SUSPEND_MEM power mode.
Patch V2:
Added the basic driver APIs for power management.
Supported the STANDBY power mode.
Patch V1:
Implemented the driver for IRQ wakeup sources.
