Subject: [PATCH] net: phy: broadcom: add support for BCM54210E
Date: Fri, 27 Jan 2017 11:47:05 +0100 [thread overview]
Message-ID: <20170127104705.25162-1-zajec5@gmail.com> (raw)
From: Rafał Miłecki <rafal@milecki.pl>
It's Broadcom PHY simply described as single-port
RGMII 10/100/1000BASE-T PHY. It requires disabling delay skew and GTXCLK
bits.
