Subject: [PATCH 2/2] ARM: dts: owl-s500-roseapplepi: Add ethernet support
Date: Mon, 28 Jun 2021 12:58:17 +0530 [thread overview]
Message-ID: <20210628072817.8269-3-mani@kernel.org> (raw)
In-Reply-To: <20210628072817.8269-1-mani@kernel.org>
From: Cristian Ciocaltea <cristian.ciocaltea@gmail.com>
Add pinctrl configuration for enabling the Ethernet MAC on RoseapplePi
SBC. Additionally, provide the necessary properties for the generic S500
ethernet node in order to setup PHY and MDIO.
