AST2700 interrupt controller(INTC) provides hardware interrupt interfaces
to interrupt of processors PSP, SSP and TSP. In INTC, each interrupt of
INT 128 to INT136 combines 32 interrupts.
Introduce a new aspeed_intc class with instance_init and realize handlers.
So far, this model only supports GICINT128 to GICINT136.
It creates 9 GICINT or-gates to connect 32 interrupts sources
from GICINT128 to GICINT136 as IRQ GPIO-OUTPUT pins.
Then, this model registers IRQ handler with its IRQ GPIO-INPUT pins which
connect to GICINT or-gates. And creates 9 GICINT IRQ GPIO-OUTPUT pins which
connect to GIC device with GIC IRQ 128 to 136.
If one interrupt source from GICINT128 to GICINT136
set irq, the OR-GATE irq callback function is called and set irq to INTC by
OR-GATE GPIO-OUTPUT pins. Then, the INTC irq callback function is called and
set irq to GIC by its GICINT IRQ GPIO-OUTPUT pins. Finally, the GIC irq
callback function is called and set irq to CPUs and
CPUs execute Interrupt Service Routine (ISR).
