Re: [PATCH v14 28/38] phy: core: add notifier infrastructure

Some PHY devices with multiple ports (e.g. USB3 and DP) require a reset

problem, as the consumer device will run into undefined behavior.

With the new PHY notifier API introduced in this patch, the consumer
driver can hook into reset events coming from a PHY device to handle the
PHY going down gracefully.

Hmmm how will phy get notified for these events. Typically there is a
separate hotplug mechanism to take care of cable changes.

Looking at implementation of this, It seems to me there is checked on
power-on, so maybe notifier maynot be right one... ?
