From 983f37ee08acb60435744f1b1e2afea2d2a09c48 Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Wed, 19 Apr 2023 20:16:29 +0100 Subject: [PATCH] arm64: dts: mt7622: handle interrupts from MT7531 switch on BPI-R64 Since commit ba751e28d442 ("net: dsa: mt7530: add interrupt support") the mt7530 driver can act as an interrupt controller. Wire up irq line of the MT7531 switch on the BananaPi BPi-R64 board, so the status of the PHYs of the five 1000Base-T ports doesn't need to be polled any more.
