Subject: [PATCH] staging: octeon: sgmii to honor disabled dt node status
|
|
|
|
With this patch, sgmii interface device tree node could be disabled and
|
|
that disabled interface will not be unnecessarily initialized.
|
|
|
|
It solves the problem with Octeon boards that have 8 sgmii or more ports
|
|
initialized but have nothing connected to them.
|
