This patch series adds phy support for AM335X platform.
This patch series is based on Generic PHY framework [1].


This series has
- adds dual musb instances support for am335x platform (just for testing)
- adds phy-amxxxx-usb driver used in AMxxxx platforms
- adds dt bindings for the phys
- removes usb-phy and replaced with generic phy apis in glue layer
No, I don't like this all. You did the one thing I tried to avoid while
posting my quick-and-dirty phy driver recently: You duplicated a lot of
code which can be served by the nop driver and added only power
on/power off callbacks.
I wanted to add phy wakeup control also, but currently phy_ops dont have an op
for wkup_ctrl
Kishon, Can we add one?
Since this should be a capability of the PHY, can't we have wkup_ctrl always
enabled if the PHY has such a capability?

No, we cant have wakeup always enabled. Normally we enable it only when we go to low power states and
if the user needs USB a wakeup source.

So how about enable/disable phy wakeup from phy suspend/resume?
or if it needs more user control,
should we implement a sysfs entry to enable wakeup?

Nope, I dont want to create another sysfs entry.

Thanks
Kishon
