Subject: [PATCH] net: phy: marvell: add SFP support for 88E1510
|
|
|
|
Add support for SFP cages connected to the Marvell 88E1512 transceiver.
|
|
88E1512 supports for SGMII/1000Base-X/100Base-FX media type with RGMII
|
|
on system interface. Configure PHY to appropriate mode depending on the
|
|
type of SFP inserted. On SFP removal configure PHY to the RGMII-copper
|
|
mode so RJ-45 port can still work.
