Re: [PATCH net-next v6] net: phy: intel-xway: Add RGMII internal delay configuration

Martin,

I've got some boards with the GPY111 phy on them and I'm finding that
modifying XWAY_MDIO_MIICTRL to change the skew has no effect unless I
do a soft reset (BCMR_RESET) first. I don't see anything in the
datasheet which specifies this to be the case so I'm interested it
what you have found. Are you sure adjusting the skews like this
without a soft (or hard pin based) reset actually works?

Best regards,

Tim

Hello Tim,

yes, you are right. It is not applied immediately. The link needs to be
toggled to get this settings active. But my experience shows that this
would be done in the further boot process anyway e.g. by restarting the
autonegotiation etc.

Hi Martin

Have you verified this? Maybe try NFS root, so the kernel is the one
up'ing the interface, before user space exists.
