From c32835ccfe683e8d97c4b68cb7d38a3009e72411 Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Thu, 10 Feb 2022 14:12:45 +0000 Subject: [PATCH] mt7622: linksys-e8450: enable using mt7531 switch irq Turns out the MT7531 switch IRQ line is connected to GPIO#53 just like on the BPi-R64, so this seems to be part of the reference design and will probably apply to most MT7622+MT7531 boards.
