Subject: [PATCH 4/8] net: pcs: airoha: add PCS driver for Airoha AN7581 SoC
|
|
|
|
Add PCS driver for Airoha AN7581 SoC for ethernet SERDES and permit usage of
|
|
external PHY or connected SFP cage. Supported modes are USXGMII,
|
|
10G-BASER, 2500BASE-X, 1000BASE-X and SGMII.
|
|
|
|
The driver probe and register the various needed registers and expose
|
|
the pcs_create and pcs_destroy symbol to make them usable by the Airoha
|
|
Ethernet driver.
