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 v7: Move most of the macros and definitions into relating source files Replace the spinlock_t with the struct raw_spinlock in imx_gpcv2_irq Code clean up
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.
