All 4 interrupts INTA, INTB, INTC, INTD share the same interrupt line connected to the GIC in the system. This is now modeled by using its own IRQ domain. Also update all relevant devicetree files to adapt to the new model. This patch set is based on Linux-5.4. Changes from v2: - Addressed Lorenzo's comments - Corrected INTx to PIN mapping. Changes from v1: - Addressed Rob, Lorenzo, Arnd's comments - Used child node for interrupt controller. - Addressed Andy Shevchenko's comments - Replaced while loop with do-while.
