Subject: [RFC PATCH 2/4] dts: phy: add GPIO number and active state used for phy reset
Date: Tue, 28 Apr 2020 04:16:46 -0700 [thread overview]
Message-ID: <1588072608-7747-3-git-send-email-sagar.kadam@sifive.com> (raw)
In-Reply-To: <1588072608-7747-1-git-send-email-sagar.kadam@sifive.com>
The GEMGXL_RST line on HiFive Unleashed is pulled low and is
using GPIO number 12. Add these reset-gpio details to dt-node
using which the linux phylib can reset the phy.
