[PATCH 5.4 33/86] dts: phy: add GPIO number and active state used for phy reset

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Date: 2021-01-26 08:46:39
Also in: lkml
Subsystem: risc-v architecture, risc-v misc soc support, the rest · Maintainers: Paul Walmsley, Palmer Dabbelt, Albert Ou, Conor Dooley, Linus Torvalds

From: Sagar Shrikant Kadam <redacted>

[ 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.
