From 082ce27ff4215a4863d885a48dc443f66f833818 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Wed, 20 Mar 2019 12:39:19 -0700 Subject: irqchip/bcm: Restore registration print with %pOF It is useful to print which interrupt controllers are registered in the system and which parent IRQ they use, especially given that L2 interrupt controllers do not call request_irq() on their parent interrupt and do not appear under /proc/interrupts for that reason. We used to print the base register address virtual address which had little value, use %pOF to print the path to the Device Tree node which maps to the physical address more easily and is what people need to troubleshoot systems.
