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.

v3: - replace PHY_MODE_* with PHY_INTERFACE_MODE_*
|
||
|
|
- replace rgmii_mode_name() with phy_modes[]
|
||
|
|
|
||
|
|
v2: - utilize phy_interface_mode_is_rgmii()
