Subject: [PATCH 14/25] phy: sparx5-serdes: add support for branching on chip
|
|
type
|
|
|
|
In preparation for lan969x, add a way to branch out on code that is to
|
|
be executed on either Sparx5 or lan969x. Initially, this is required to
|
|
branch out when checking the SERDES types and SERDES speeds, since the
|
|
handling of these differ on the two platforms. This will also be used by
|
|
the lan969x driver introduced in a subsequent patch.
