Hi, Rafael, Pavel,
I know you may be busy. Just a gentle ping on this topic. It would be nice
to have your input in this.
Thank you,

In the patch I proposed in this thread the restoring is done in PHY
Hi, Rafael, Pavel,
I recently posted a patch for re-configuring an ethernet PHY on its
.resume() callback as this PHY is in a setup with SAMA7G5 SoC that supports
a power saving mode (called backup). In this power saving mode most of the
SoC devices' power is cut of (except the RAM + its controlle

KSZ9131 is used in setups with SAMA7G5. SAMA7G5 supports a special
power saving mode (backup mode) that cuts the power for almost all
parts of the SoC. The rail powering the ethernet PHY is also cut off.
When resuming, in case the PHY has been configured on probe with
slew rate or DLL settings thes
