From 9a4259e59694136add708608fce861a1beff9635 Mon Sep 17 00:00:00 2001 From: Kieran Bingham Date: Wed, 9 Mar 2022 19:06:31 +0000 Subject: [PATCH] arm64: dts: renesas: falcon-cpu: Use INTC_EX for SN65DSI86 The INTC block is a better choice for handling the interrupts on the V3U as the INTC will always be powered, while the GPIO block may be de-clocked if not in use. Further more, it may be likely to have a lower power consumption as it does not need to drive the pins. Switch the interrupt parent and interrupts definition from gpio1 to irq0 on intc_ex, and configure the PFC accordingly.
