From 7323ef2ffab9f25aa92ea786870150baa9db7004 Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Thu, 10 Feb 2022 13:48:10 +0000 Subject: [PATCH] mt7622: bpi-r64: enable using mt7531 switch irq Now that we support link-state-change interrupts, wire up MT7531 IRQ line which is connected to GPIO#53 according to the schematics [1]. As a result, PHY state no longer needs to be polled on that board.
