Subject: [PATCH 7/8] net: pcs: airoha: add support for optional xfi reset line
|
|
|
|
On Airoha AN7583 there is a dedicated reset line for the PON XFI Serdes.
|
|
This is needed to permit changing the WAN sel register or the system
|
|
will stall on accessing the XFI register.
|
|
|
|
Add support for this optional dedicated reset to permit correct
|
|
configuration of the PON Serdes.
