From 0a49f0d1958440f7928047433c983eece05a3723 Mon Sep 17 00:00:00 2001

Subject: [PATCH 3/3] net: ibm: emac: support RGMII-[RX|TX]ID phymode
The RGMII spec allows compliance for devices that implement an internal
delay on TXC and/or RXC inside the transmitter. This patch adds the
necessary RGMII_[RX|TX]ID mode code to handle such PHYs with the
emac driver.
Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
---
v3: - replace PHY_MODE_* with PHY_INTERFACE_MODE_*
- replace rgmii_mode_name() with phy_modes[]
v2: - utilize phy_interface_mode_is_rgmii()
