Subject: [PATCH AUTOSEL 5.4 18/26] dts: phy: add GPIO number and active state used for phy reset
Date: Tue, 19 Jan 2021 20:26:55 -0500 [thread overview]
Message-ID: <20210120012704.770095-18-sashal@kernel.org> (raw)
In-Reply-To: <20210120012704.770095-1-sashal@kernel.org>
From: Sagar Shrikant Kadam <sagar.kadam@sifive.com>
[ Upstream commit a0fa9d727043da2238432471e85de0bdb8a8df65 ]
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.
