Subject: [PATCHv1] ARM: dts/imx6q-bx50v3: Add IRQ support for internal switch
Date:   Wed,  5 Aug 2020 15:58:17 +0200
Message-Id: <20200805135817.391409-1-sebastian.reichel@collabora.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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.
