Subject: [PATCH] net/phy: Inphi IN112525_s03 retimer updates
|
||
|
|
|
||
|
|
The retimer doesn't get probed in linux due to the fact that it's a
|
||
|
|
non-standard clause-45 device. Hardcoding the phyid in device-tree
|
||
|
|
and adding custom routines for registry read/write operations
|
||
|
|
solves the issue.
