Subject: [PATCH 05/16] net: dsa: mt7530: refactor SGMII PCS creation
|
|
|
|
Instead of macro templates use a dedidated function and allocated
|
|
regmap_config when creating the regmaps for the pcs-mtk-lynxi
|
|
instances.
|
|
This is in preparation to switching to use unlocked regmap accessors
|
|
and have regmap's locking API handle locking for us.
