From 675abeb9fc0e24a25eb5f95a948e3738aef64875 Mon Sep 17 00:00:00 2001 From: Sebastian Reichel Date: Wed, 5 Aug 2020 15:58:17 +0200 Subject: [PATCH] ARM: dts: imx6q-bx50v3: Add IRQ support for internal switch This adds missing interrupt support for the internal Marvell switch, so that the kernel does not have to keep polling the PHYs on the bit-banged MDIO bus all the time.
