Subject: [PATCH] ARM: dts: add phy-reset property for rk3066a-rayeager emac
Date: Tue,  7 Nov 2017 10:49:19 +0800	[thread overview]
Message-ID: <1510022959-19440-1-git-send-email-zyw@rock-chips.com> (raw)

The ethernet phy of rk3066a-rayeager has a reset pin, it controlled by
GPIO1_D6, this pin should be pull down then pull up to reset the phy.
Add a phy-reset property in emac, make the phy can be reset when emac
power on.
