Subject: [PATCH v2] arm64: allwinner: h6: orangepi-one-plus: Add Ethernet support
Date: Fri, 3 May 2019 17:29:28 +0530 [thread overview]
Message-ID: <20190503115928.27662-1-jagan@amarulasolutions.com> (raw)
Add Ethernet support for orangepi-one-plus board,
- Ethernet port connected via RTL8211E PHY
- PHY suppiled with
GMAC-2V5, fixed regulator with GMAC_EN pin via PD6
GMAC-3V, which is supplied by VCC3V3-MAC via aldo2
- RGMII-RESET pin connected via PD14
Signed-off-by: Jagan Teki <jagan@amarulasolutions.com>
